155-500: The machines were not a part of the Apple Macintosh line of computers; they were designed to run IBM 's AIX operating system and their ROM specifically prevented booting the classic Mac OS . This makes them the last non-Macintosh desktop computers made by Apple to date. The 500/132, 700/150, and 700/200 sold in the U.S. market for $ 11,000, $ 15,000 and $ 19,000, respectively. Apple Network Servers are not to be confused with

310-636: A Mach kernel and BSD foundations, a virtualization layer for old Mac OS apps (codenamed Blue Box), and an implementation of NeXTSTEP APIs called OpenStep (codenamed Yellow Box). Apple open-sourced the core of Rhapsody as the Darwin operating system. After several developer previews, Apple also introduced the Carbon API, which provided a way for developers to more easily make their apps native to Mac OS X without rewriting them in Yellow Box. Mac OS X

465-462: A PowerPC 604 CPU clocked at 132 MHz, and the ANS 700/150 has the same family CPU but clocked at 150 MHz. Both have a L1 cache of 32 kB. The ANS 700/200 features the more advanced PowerPC 604e clocked at 200 MHz, with an L1 cache of 64 kB. The L2 cache of the ANS is mounted on a SIMM , with a standard size of 512 kB for the 500 and 1 MB for the 700s. Any ANS may have

620-517: A Primetime Emmy . In the 2000s, Apple continued to use successful marketing campaigns to promote the Mac line, including the Switch and Get a Mac campaigns. Apple's focus on design and build quality has helped establish the Mac as a high-end, premium brand. The company's emphasis on creating iconic and visually appealing designs for its computers has given them a "human face" and made them stand out in

775-520: A store-within-a-store that would better showcase Macs and their software and peripherals. According to Apple, the Mac's share of computer sales in those stores went from 3% to 14%. In November, the online Apple Store launched with built-to-order Mac configurations without a middleman. When Tim Cook was hired as chief operations officer in March 1998, he closed Apple's inefficient factories and outsourced Mac production to Taiwan. Within months, he rolled out

930-522: A "masterpiece." Before the Macintosh, high-tech marketing catered to industry insiders rather than consumers, so journalists covered technology like the "steel or automobiles" industries, with articles written for a highly technical audience. The Macintosh launch event pioneered event marketing techniques that have since become "widely emulated" in Silicon Valley , by creating a mystique about

1085-523: A 0.5 μm CMOS process with four levels of interconnect. The die was 85 mm large drawing 2.2 W at 80 MHz. The 603 architecture is the direct ancestor to the PowerPC 750 architecture, marketed by Apple as the PowerPC "G3". The 603 was intended to be used for portable Apple Macintosh computers but could not run 68K emulation software with performance Apple considered adequate, due to

1240-470: A DAT tape streamer can be added to the free slots. Optionally, the ANS 700 also supports redundant and hot-swappable power supply units and an internal drive rack for two further fixed hard drives. The case is large and heavy, at a height of 24.5 in (62 cm), a width of 16.5 in (42 cm), a depth of 18 in (46 cm) and a weight of over 80 lb (36 kg), with exact weight depending on hardware configuration. That means that while it

1395-540: A L2 cache that may have a capacity of 128  MB , and more powerful branch and load/store units that had more buffers, the 620 was very powerful. The branch history table was also larger and could dispatch more instructions so that the processor can handle out-of-order execution more efficiently than the 604. The floating-point unit was also enhanced compared to the 604. With a faster fetch cycle and support for several key instructions in hardware (like sqrt) made it, combined with faster and wider data buses, more efficient than

1550-460: A Mac program, HyperCard , whose cards store any information—text, image, audio, video—with the memex -like ability to semantically link cards together. HyperCard was released in 1987 and bundled with every Macintosh. In the late 1980s, Jean-Louis Gassée , a Sculley protégé who had succeeded Jobs as head of the Macintosh division, made the Mac more expandable and powerful to appeal to tech enthusiasts and enterprise customers. This strategy led to

1705-685: A bridge chip). The bus later evolved into the GX bus of the POWER4 , and later GX+ and GX++ in POWER5 and POWER6 respectively. The GX bus is also used in IBM's z10 and z196 System z mainframes. The PowerPC 602 was a stripped-down version of PowerPC 603, specially made for game consoles by Motorola and IBM, introduced in February 1995. It has smaller L1 caches (4 KB instruction and 4 KB data),

1860-558: A crowded market. Apple has long made product placements in high-profile movies and television shows to showcase Mac computers, like Mission: Impossible , Legally Blonde , and Sex and the City . Apple is known for not allowing producers to show villains using Apple products. Its own shows produced for the Apple TV+ streaming service feature prominent use of MacBooks. The Mac is known for its highly loyal customer base. In 2022,

2015-504: A die measuring 74 mm . The 601+ design was remapped from CMOS-4s to CMOS-5x by an IBM-only team. To avoid time-to-market delays from design tool changes and commonizing fab groundrules, both the 601 and 601+ were designed with IBM EDA tools on IBM systems and were fabricated in IBM-only facilities. The PowerPC 603 was the first processor implementing the complete 32-bit PowerPC Architecture as specified. Introduced in 1994, it

2170-569: A display cutout incorporating a 1080p webcam. The Mac Studio with M2 Max and M2 Ultra chips and the Mac Pro with M2 Ultra chip was unveiled at WWDC 2023, and the Intel-based Mac Pro was discontinued on the same day, completing the Mac transition to Apple silicon chips. The Mac Studio was received positively as a modest upgrade over the previous generation, albeit similarly priced PCs could be equipped with faster GPUs. However,

2325-468: A dual primary power configuration (independent primary power, possibly, and desirably, from different power panels, one possibly backed up by an uninterruptible power supply ) by removing the IEC input power connector and physically and electrically connecting two input power cordsets, one to each of the redundant PSUs. However, this modification very likely invalidates the machine's UL Listing. Nevertheless, such

2480-427: A four-stage pipeline and five execution units: integer unit, floating-point unit, branch prediction unit , load/store unit and a system registry unit. It has separate 8 KB L1 caches for instructions and data and a 32/64 bit 60x memory bus, reaching up to 120 MHz at 3.8 V. The 603 core did not have hardware support for SMP . The PowerPC 603 had 1.6 million transistors and was fabricated by IBM and Motorola in

2635-454: A last-ditch attempt to fend off Windows, Apple yielded and started a Macintosh clone program, which allowed other manufacturers to make System 7 computers. However, this only cannibalized the sales of Apple's higher-margin machines. Meanwhile, Windows 95 was an instant hit with customers. Apple was struggling financially as its attempts to produce a System 7 successor had all failed with Taligent, Star Trek , and Copland , and its hardware

2790-445: A lower energy consumption. The die was 47 mm small manufactured on a 0.25 μm CMOS process with five levels of interconnect, and drew 6 W at 250 MHz. It operated at speeds between 250 and 400 MHz and supported a memory bus up to 100 MHz. While Apple dropped the 604ev in 1998 in favor for the PowerPC 750 , IBM kept using it in entry-level models of its RS/6000 computers for several years. The PowerPC 620

2945-402: A magnetic latch that secures the lid elegantly. The design language of consumer Macs shifted again from colored plastics to white polycarbonate with the introduction of the 2001 Dual USB "Ice" iBook . To increase the iBook's durability, it eliminated doors and handles, and gained a more minimalistic exterior. Ive attempted to go beyond the quadrant with Power Mac G4 Cube , an innovation beyond

3100-813: A merger of NeXTSTEP and Mac OS as the foundation of Apple's new operating system strategy. At the time, Jobs only served as advisor, and Amelio was released in July 1997. Jobs was formally appointed interim CEO in September, and permanent CEO in January 2000. To continue turning the company around, Jobs streamlined Apple's operations and began layoffs. He negotiated a deal with Bill Gates in which Microsoft committed to releasing new versions of Office for Mac for five years, investing $ 150 million in Apple, and settling an ongoing lawsuit in which Apple alleged that Windows had copied

3255-415: A miniaturized design with a glossy dark gray cylindrical body and internal components organized around a central cooling system. Tech reviewers praised the 2013 Mac Pro for its power and futuristic design; however, it was poorly received by professional users, who criticized its lack of upgradability and the removal of expansion slots. The iMac was refreshed with a 5K Retina display in 2014, making it

3410-448: A modification could implement a true N+1 redundancy configuration for the ANS 700s. The Network Servers were sold exclusively with AIX , in a version called " AIX for Apple Network Servers " with some Apple-specific features, like AppleShare services, added; two revisions, 4.1.4 and 4.1.5, exist. Apple's own Unix variant A/UX had already been discontinued and does not support the PowerPC. Due to their AIX OS and hardware similarities,

3565-508: A new ERP system and implemented just-in-time manufacturing principles. This practically eliminated Apple's costly unsold inventory, and within one year, Apple had the industry's most efficient inventory turnover. Jobs's top priority was "to ship a great new product". The first is the iMac G3 , an all-in-one computer that was meant to make the Internet intuitive and easy to access. While PCs came in functional beige boxes, Jony Ive gave

3720-691: A new standardized computing platform, which led to the creation of the PowerPC processor architecture, and the Taligent operating system. In 1992, Apple introduced the Macintosh Performa line, which "grew like ivy" into a disorienting number of barely differentiated models in an attempt to gain market share. This backfired by confusing customers, but the same strategy soon afflicted the PowerBook line. Michael Spindler continued this approach when he succeeded Sculley as CEO in 1993. He oversaw

3875-622: A personal computer. Beginning in 1994 with the Power Macintosh , the Mac transitioned from Motorola 68000 series processors to PowerPC . Macintosh clones by other manufacturers were also briefly sold afterwards. The line was refreshed in 1998 with the launch of iMac G3 , reinvigorating the line's competitiveness against commodity IBM PC compatibles . Macs transitioned to Intel x86 processors by 2006 along with new sub-product lines MacBook and Mac Pro. Since 2020, Macs have transitioned to Apple silicon chips based on ARM64 . In

4030-511: A problem with stuck keys and letters being skipped or repeated. iFixit attributed this to the ingress of dust or food crumbs under the keys, jamming them. Since the Butterfly keyboard was riveted into the laptop's case, it could only be serviced at an Apple Store or authorized service center . Apple settled a $ 50m class-action lawsuit over these keyboards in 2022. These same models were afflicted by "flexgate": when users closed and opened

4185-509: A program to repair affected keyboards free of charge. Higher-end models of the 15-inch 2018 MacBook Pro faced another issue where the Core i9 processor reached unusually high temperatures, resulting in reduced CPU performance from thermal throttling. Apple issued a patch to address this issue via a macOS supplemental update, blaming a "missing digital key" in the thermal management firmware. The 2019 16-inch MacBook Pro and 2020 MacBook Air replaced

4340-446: A recycler and crushed. It was once not uncommon for a well-featured ANS to barely recover the $ 0.99 minimum bid on eBay. Shipping of an ANS is expensive, about $ 100 from a U.S.-to-U.S. location, if sent via bulk shipping . Few, if any, replacement parts are available, particularly not the mechanical components. As of 2019, Apple Network Servers are sometimes seen and sold for over US$ 2,000 on eBay. Mac (computer) Mac

4495-486: A single-precision floating-point unit and a scaled back branch prediction unit. It was offered at speeds ranging from 50 to 80 MHz, and drew 1.2 W at 66 MHz. It consisted of 1 million transistors and it was 50 mm large manufactured in a 0.5 μm, CMOS process with four levels of interconnect. 3DO developed the M2 game console that used two PowerPC 602, but it was never marketed. On October 21, 1996,

4650-484: A strengthened hinge instead of a mechanical latch to keep it closed, ports on the sides rather than on the back, and the first laptop with built-in Wi-Fi . It became the best selling laptop in the U.S. during the fourth quarter of 1999. The professional-oriented Titanium PowerBook G4 was released in 2001, becoming the lightest and thinnest laptop in its class, and the first laptop with a wide-screen display; it also debuted

4805-480: A thinner "Butterfly" keyboard, and replaced function keys with the Touch Bar . The Touch Bar was criticized for making it harder to use the function keys by feel, as it offered no tactile feedback. Many users were also frustrated by the need to buy dongles , particularly professional users who relied on traditional USB-A devices, SD cards , and HDMI for video output. A few months after its release, users reported

Apple Network Server - Misplaced Pages Continue

4960-644: A variety of RS/6000 workstations and SMP servers from IBM and Groupe Bull . IBM was the sole manufacturer of the 601 and 601+ microprocessors in its Burlington, Vermont and East Fishkill, New York production facilities. The 601 used the IBM CMOS-4s process and the 601+ used the IBM CMOS-5x process. An extremely small number of these 601 and 601+ processors were relabeled with Motorola logos and part numbers and distributed through Motorola. These facts are somewhat obscured given there are various pictures of

5115-476: A variety of design flaws, some of them severe, related to other aspects of the computers' design, including networking performance and stability, bus problems (width, speed, contention, and complexity), ROM bugs, and hard disk performance. None of the problems of the 5200 line, aside from 68K emulation performance, were inherently due to the 603. Rather, the processor was retrofitted to be used with 68K motherboards and other obsolete parts. The site Low End Mac rates

5270-405: Is a 32- or 64-bit 60x bus that operates at clock rates up to 50 MHz. The PowerPC 604 contains 3.6 million transistors and was fabricated by IBM and Motorola with a 0.5 μm CMOS process with four levels of interconnect. The die measured 12.4 mm by 15.8 mm (196 mm ) and drew 14-17 W at 133 MHz. It operated at speeds between 100 and 180 MHz. The PowerPC 604e

5425-567: Is a family of personal computers designed and marketed by Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to a type of apple called McIntosh . The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac , Mac Mini , Mac Studio , and Mac Pro desktops. Macs are sold with the macOS operating system, which is not licensed to other manufacturers and exclusively bundled with Mac computers. Jef Raskin conceived

5580-517: Is about the right width for a 19-inch rack, it requires at least 14 rack units in height. A third model in a smaller rack-mount case without the large disk array, the Network Server 300 (code named "Deep Dish", as in a deep dish pizza), never got past the prototype stage. Also in development but never released were CPU cards featuring two CPUs . Power Macintosh 9500 CPU cards, which were available with dual processors, were not compatible with

5735-644: Is also common to both machines and connected through the Grand Central chip. The ANS lacks the MESH SCSI chip (53CF94/6 derived Apple SCSI chip) which is present on the PM9600 and supports the internal Fast SCSI bus. Grand Central provides support for eleven system interrupts. On both the Macintosh and the ANS, each PCI slot contains only one interrupt line (up to four supported in PCI spec.) and each interrupt line

5890-467: Is attributed to significant financial troubles at Apple in early 1997. CEO Gil Amelio cancelled both Network Server and OpenDoc in the same meeting as it was determined that they were low priorities. The Apple Network Server's hardware was supposed to be based on a new logic board design specific to the product. During the development of the hardware, Apple abandoned the original mainboard design for unconfirmed reasons. In order to move forward and ship

6045-578: Is free of toxic chemicals like mercury , bromide , and PVC , and with smaller packaging. The enclosures of the iMac and unibody MacBook Pro were redesigned with the more recyclable aluminum and glass. On February 24, 2011, the MacBook Pro became the first computer to support Intel's new Thunderbolt connector, with two-way transfer speeds of 10 Gbit/s, and backward compatibility with Mini DisplayPort . Due to deteriorating health, Steve Jobs resigned as CEO on August 24, 2011, and Tim Cook

6200-413: Is installed. This is an absolute restriction built into the machine's ROM-DIMM. If even one RAM DIMM is non-parity, then parity checking is turned off for all RAM, in which case 70 ns RAM DIMMs are acceptable. FPM or EDO RAM DIMMs are acceptable, in any order, as the machine treats EDO RAM DIMMs as FPM RAM DIMMs. All Network Servers feature an internal two-channel Wide SCSI -2 controller (narrow, to

6355-541: Is sometimes called PowerPC 603ev . The 603e and 603ev have 2.6 million transistors each and are 98 mm and 78 mm large respectively. The 603ev draws a maximum of 6 W at 300 MHz. The PowerPC 603e was the first mainstream desktop processor to reach 300 MHz, as used in the Power Macintosh 6500 . The 603e was also used in accelerator cards from Phase5 for the Amiga line of computers, with CPUs ranging in speeds from 160 to 240 MHz. The PowerPC 603e

6510-555: Is specific to its unique mission function. Starting at the top level bus and working downward in the bus hierarchy, at the top level is the CPU bus with a Hammerhead controller (Apple Part # 343S1190) which is also found on the PM9500. The CPU, as mentioned, is a PowerPC 604 or 604e. The CPU bus-to-PCI bus bridges are Bandit controllers (343S0020). Both the ANS and the PM9500 have two Bandit controllers and two separate PCI busses. All devices at

6665-536: Is still sold today by IBM and Freescale, and others like Atmel and Honeywell who makes the radiation hardened variant RHPPC . The PowerPC 603e was also the heart of the BeBox from Be Inc. The BeBox is notable since it is a multiprocessing system, something the 603 wasn't designed for. IBM also used PowerPC 603e processors in the IBM ThinkPad 800 series . In certain digital oscilloscope series, LeCroy used

6820-399: Is used by only one device. The interrupt map is different in the two machines, and this represents the most likely reason why inserting a PM9500 or PM9600 ROM in an ANS will not allow the machine to boot. The firmware expects certain interrupts to correspond to certain events, but the interrupt signal is physically connected to a different device than the firmware expects. The ANS 500/132 uses

6975-706: The Apple Workgroup Servers and the Macintosh Servers, which were Macintosh workstations that shipped with server software and used Mac OS; the sole exception, the Workgroup Server 95—a Quadra 950 with an added SCSI controller that shipped with A/UX —was also capable of running Mac OS. Apple did not have comparable server hardware in their product lineup again until the introduction of the Xserve in 2002. The product's short lifespan

7130-451: The Crusoe processor. With progress having been demonstrated in the development of dynamic translation software, such as Digital's FX!32 technology, skepticism was expressed about dedicating hardware resources to running foreign binaries when such resources could be used to improve native performance instead, this also benefiting the performance of translated binaries. "PowerPC 625" was

7285-472: The Mac transition to Intel processors , because the operating system had been developed for both architectures since the beginning. PowerPC apps run using transparent Rosetta emulation, and Windows boots natively using Boot Camp . This transition helped contribute to a few years of growth in Mac sales. After the iPhone 's 2007 release, Apple began a multi-year effort to bring many iPhone innovations "back to

7440-462: The Macintosh 512K with improved performance and an external floppy drive. The Macintosh is credited with popularizing the graphical user interface, Jobs's fascination with typography gave it an unprecedented variety of fonts and type styles like italics, bold, shadow, and outline. It is the first WYSIWYG computer, and due in large part to PageMaker and Apple's LaserWriter printer, it ignited

7595-533: The Rosetta 2 translation layer, and iOS and iPadOS apps distributed via the App Store . These Mac models come equipped with high-speed Thunderbolt 4 or USB 4 connectivity, with speeds up to 40 Gbit/s. Apple silicon Macs have custom integrated graphics rather than graphics cards. MacBooks are recharged with either USB-C or MagSafe connectors, depending on the model. Apple sells accessories for

7750-643: The SD card slot. On March 8, 2022, the Mac Studio was unveiled, also featuring the M1 Max chip and the new M1 Ultra chip in a similar form factor to the Mac Mini. It drew highly positive reviews for its flexibility and wide range of available ports. Its performance was deemed "impressive", beating the highest-end Mac Pro with a 28-core Intel Xeon chip, while being significantly more power efficient and compact. It

7905-533: The StyleWriter printer and the Newton PDA. These changes were meant to refocus Apple's engineering, marketing, and manufacturing efforts so that more care could be dedicated to each product. Jobs also stopped licensing Mac OS to clone manufacturers, which had cost Apple ten times more in lost sales than it received in licensing fees. Jobs made a deal with the largest computer reseller, CompUSA , to carry

However, Ive considered it beneficial, because it helped Apple gain experience in complex machining and miniaturization. The development of a successor to the old Mac OS was well underway. Rhapsody had been previewed at WWDC 1997, featuring

8215-418: The desktop publishing market, turning the Macintosh from an early let-down into a notable success. Levy called desktop publishing the Mac's "Trojan horse" in the enterprise market, as colleagues and executives tried these Macs and were seduced into requesting one for themselves. PageMaker creator Paul Brainerd said: "You would see the pattern. A large corporation would buy PageMaker and a couple of Macs to do

8370-526: The fabless semiconductor company Quantum Effect Devices (QED) announced a PowerPC 603-compatible processor named " PowerPC 603q " at the Microprocessor Forum . Despite its name, it did not have anything in common with any other 603. It was a from the ground up implementation of the 32-bit PowerPC architecture targeted at the high-end embedded market developed over two years. As such, it was small, simple, energy efficient, but powerful; equaling

New Macs include the white "Sunflower" iMac G4 . Ive designed a display to swivel with one finger, so that it "appear[ed] to defy gravity". In 2003, Apple released the aluminum 12-inch and 17-inch PowerBook G4 , proclaiming the "Year of

8835-595: The iWork office suite. Serlet and Tevanian were both initiating the secret project asked by Steve Jobs to propose to Sony executives, in 2001, to sell Mac OS X on Vaio laptops. They showed them a demonstration at a golf party in Hawaii , with the most expensive Vaio laptop they could have acquired. But due to bad timing, Sony refused, arguing their Vaio sales just started to grow after years of difficulties. With PowerPC chips falling behind in performance, price, and efficiency, Steve Jobs announced in 2005

8990-463: The "Motorola MPC601", particularly one specific case of masterful Motorola marketing where the 601 was named one of Time Magazine ' s 1994 "Products of the Year" with a Motorola marking. An updated version, the PowerPC 601v or PowerPC 601+ , operating at 90 to 120 MHz was introduced in 1994. It was fabricated in a newer 0.5 μm CMOS process with four levels of interconnect, resulting in

9145-497: The 1 MB cache card fitted. The system bus speed is 44 MHz for the 500, and 50 MHz for the 700s or any ANS to which the 200 MHz processor card had been fitted. The ANS logic board has eight 168-pin DIMM parity RAM slots with four of them free (with a maximum amount of 512 MB of RAM specified). The ANS 500/132 shipped with 32 MB of RAM installed (4 × 8 MB 60 ns parity DIMMs manufactured by IBM) and

9300-480: The 88110 bus as the basis for the 60x bus helped schedules in a number of ways. It helped the Apple Power Macintosh team by reducing the amount of redesign of their support ASICs and it reduced the amount of time required for the processor designers and architects to propose, document, negotiate, and close a new bus interface (successfully avoiding the "Bus Wars" expected by the 601 management team if

9455-448: The 88110 bus or the previous RSC buses hadn't been adopted). Worthy to note is that accepting the 88110 bus for the benefit of Apple's efforts and the alliance was at the expense of the first IBM RS/6000 system design team's efforts who had their support ASICs already implemented around the RSC's totally different bus structure. This 60x bus later became a fairly long lived basic interface for

For all practical purposes, the maximum RAM configuration is 4 × 128 MB parity DIMMs (512 MB, total) or 8 × 64 MB parity DIMMs (also 512 MB total). The machine will not POST (i.e., will not pass the P ower- o n S ystem T est) if more than 512 MB

9765-598: The ANS uses the Bandit PCI bridge, just as the PM9500 does. The PCI bus arbiters are also identical (343S0182). The bus arbiters receive the PCI Bus Request signals and issue the Bus Grant Signals to the PCI slots and to the PCI bridge chips (Bandit). The interrupt manager and logic board IO controller is also the same. Both use Grand Central (343S1125). Grand Central is a device on the PCI bus. At

9920-525: The ANS. An ANS 500/132 may be upgraded to an ANS 500/200 by installing the 200 MHz processor accessory card. It is possible to upgrade an ANS 500 to an ANS 700 or to downgrade an ANS 700 to an ANS 500 simply by exchanging the power back panel and PSU(s), but it is necessary to completely disassemble the base of the ANS in order to accomplish such an upgrade or downgrade. An ANS 700 has but one input power connection, even though it can have dual, independent PSUs. However, an ANS 700 may be easily converted into

10075-561: The Afterburner card for faster video encoding. Almost every part of the new Mac Pro is user-replaceable, with iFixit praising its high user-repairability. It received positive reviews, with reviewers praising its power, modularity, quiet cooling, and Apple's increased focus on professional workflows. In April 2018, Bloomberg reported Apple's plan to replace Intel chips with ARM processors similar to those in its phones, causing Intel's shares to drop by 9.2%. The Verge commented on

10230-805: The American Customer Satisfaction Index gave the Mac the highest customer satisfaction score of any personal computer, at 82 out of 100. In that year, Apple was the fourth largest vendor of personal computers, with a market share of 8.9%. Apple outsources the production of its hardware to Asian manufacturers like Foxconn and Pegatron . As a highly vertically integrated company developing its own operating system and chips, it has tight control over all aspects of its products and deep integration between hardware and software. All Macs in production use ARM -based Apple silicon processors and have been praised for their performance and power efficiency. They can run Intel apps through

10385-400: The Apple silicon-based Mac Pro was criticized for several regressions, including memory capacity and a complete lack of CPU or GPU expansion options. A 15-inch MacBook Air was also introduced, and is the largest display included on a consumer-level Apple laptop. The MacBook Pro was updated on October 30, 2023, with updated M3 Pro and M3 Max chips using a 3 nm process node, as well as

10540-450: The Apple system design team was familiar with the I/O bus structure from Motorola's 88110 and this I/O bus implementation was well defined and documented, the 601 team adopted the bus technology to improve time to market. The bus was renamed the 60x bus once implemented on the 601. These Motorola (and a small number of Apple) designers joined over 120 IBM designers in creating the 601. Using

10695-604: The Bandit PCI Bridge and associated arbiter chip can directly (no PCI-PCI bridge required) support at least six PCI devices given proper firmware support. Going down further in the hierarchy, the Grand Central chip is a sort of I/O bus for miscellaneous logic board devices. Both the ANS and the PM9500 use the CURIO chip (AM79C950, custom part from AMD) to support serial ports, a slow (5 MB/s, 53C94/96 based) SCSI bus and 10 Mbit/s ethernet. The SWIM floppy controller

10850-555: The CD-ROM drive, and to any hard drives which have been installed with the Apple accessory Narrow SCSI-2 installation kit), an external 25-pin SCSI-1 connector and a standard 1.44 MB " SuperDrive " floppy. Six free PCI slots are available for expansion—parts supported under AIX include two Ethernet cards and a SCSI RAID card. Other ports include one ADB port, two serial ports and one AAUI port. Unlike all other Apple computers of

11005-781: The CPU bus level are identical between the ANS and PM9500. On both systems the CPU Bus Clock is supplied by the removable CPU card. However, on the ANS the clock buffer which splits the System Clock for all the CPU Bus Devices is on the logic board, whereas on the PowerMac 9500 the clock buffer is on the CPU card. The memory data lane controllers are different on the ANS from the ones on the PM9500, presumably because of added support for parity memory. The ANS memory data lane controllers are 343S1161 instead of 343S1141 as on

11160-567: The FPU in the 604. The system bus was a wider and faster 128-bit memory bus called the 6XX bus . It was designed to be a system bus for multiprocessor systems where processors, caches, memory and I/O was to be connected, assisted by a system control chip. It supports both 32- and 64-bit PowerPC processors, memory addresses larger than 32 bits, and NUMA environments. It was also used in POWER3, RS64 and 601, as well as 604-based RS/6000 systems (with

11315-557: The Internet's appeal to consumers, 32% of iMac buyers had never used a computer before, and 12% were switching from PCs. The iMac reestablished the Mac's reputation as a trendsetter: for the next few years, translucent plastic became the dominant design trend in numerous consumer products. Apple knew it had lost its chance to compete in the Windows-dominated enterprise market, so it prioritized design and ease of use to make

11470-418: The Mac Pro, Apple executives admitted in 2017 that the 2013 Mac Pro had not met expectations, and said that the company had designed themselves into a "thermal corner", preventing them from releasing a planned dual-GPU successor. Apple also unveiled their future product roadmap for professional products, including plans for an iMac Pro as a stopgap and an expandable Mac Pro to be released later. The iMac Pro

11625-519: The Mac became a "digital hub" and centerpiece with several new applications. In October 1999, the iMac DV gained FireWire ports, allowing users to connect camcorders and easily create movies with iMovie ; the iMac gained a CD burner and iTunes , allowing users to rip CDs, make playlists, and burn them to blank discs. Other applications include iPhoto for organizing and editing photos, and GarageBand for creating and mixing music and other audio. The digital lifestyle strategy entered other markets, with

11780-420: The Mac more appealing to average consumers, and even teens. The "Apple New Product Process" was launched as a more collaborative product development process for the Mac, with concurrent engineering principles. From then, product development was no longer driven primarily by engineering and with design as an afterthought. Instead, Ive and Jobs first defined a new product's "soul", before it was jointly developed by

11935-512: The Mac", including multi-touch gesture support, instant wake from sleep, and fast flash storage . At Macworld 2008, Jobs introduced the first MacBook Air by taking it out of a manila envelope, touting it as the "world's thinnest notebook". The MacBook Air favors wireless technologies over physical ports, and lacks FireWire , an optical drive , or a replaceable battery. The Remote Disc feature accesses discs in other networked computers. A decade after its launch, journalist Tom Warren wrote that

12090-499: The Mac's interface. In exchange, Apple made Internet Explorer the default Mac browser. The deal was closed hours before Jobs announced it at the August 1997 Macworld. Jobs returned focus to Apple. The Mac lineup had been incomprehensible, with dozens of hard-to-distinguish models. He streamlined it into four quadrants, a laptop and a desktop each for consumers and professionals. Apple also discontinued several Mac accessories, including

12245-492: The Mac's transition from Motorola 68000 series to PowerPC and the release of Apple's first PowerPC machine, the well-received Power Macintosh . Many new Macintoshes suffered from inventory and quality control problems. The 1995 PowerBook 5300 was plagued with quality problems, with several recalls as some units even caught fire. Pessimistic about Apple's future, Spindler repeatedly attempted to sell Apple to other companies, including IBM, Kodak, AT&T, Sun, and Philips. In

12400-703: The Mac, including the Studio Display and Pro Display XDR external monitors, the AirPods line of wireless headphones, and keyboards and mice such as the Magic Keyboard , Magic Trackpad , and Magic Mouse . Macs run the macOS operating system, which is the second most widely used desktop OS according to StatCounter . Macs can also run Windows , Linux , or other operating systems through virtualization , emulation, or multi-booting . PowerPC 600#PowerPC 604 The PowerPC 600 family

12555-519: The Mac, the Apple M1 , and a series of Macs that would ship with the M1: the MacBook Air , Mac Mini , and the 13-inch MacBook Pro . These new Macs received highly positive reviews, with reviewers highlighting significant improvements in battery life, performance, and heat management compared to previous generations. The iMac Pro was discontinued on March 6, 2021. On April 20, 2021, a new 24-inch iMac

12710-472: The MacBook Air had "immediately changed the future of laptops", starting the ultrabook trend. OS X Lion added new software features first introduced with the iPad , such as FaceTime , full-screen apps, document autosaving and versioning, and a bundled Mac App Store to replace software install discs with online downloads. It gained support for Retina displays , which had been introduced earlier with

12865-477: The Macintosh project in 1979, which was usurped and redefined by Apple co-founder Steve Jobs in 1981. The original Macintosh was launched in January 1984, after Apple's "1984" advertisement during Super Bowl XVIII . A series of incrementally improved models followed, sharing the same integrated case design. In 1987, the Macintosh II brought color graphics, but priced as a professional workstation and not

13020-509: The Macintosh project. Conceived in 1979 by Jef Raskin , Macintosh was envisioned as an affordable, easy-to-use computer for the masses. Raskin named the computer after his favorite type of apple, the McIntosh . The initial team consisted of Raskin, hardware engineer Burrell Smith , and Apple co-founder Steve Wozniak . In 1981, Steve Jobs was removed from the Lisa team and joined Macintosh, and

13175-483: The Macintosh to lose its chance at becoming the dominant personal computer platform. Though senior management demanded high-margin products, a few employees disobeyed and set out to create a computer that would live up to the original Macintosh's slogan, "[a] computer for the rest of us", which the market clamored for. In a pattern typical of Apple's early era, of skunkworks projects like Macintosh and Macintosh II lacking adoption by upper management who were late to realize

13330-602: The Network Servers are mostly binary compatible with the RS/6000 series. However, applications which rely on early RS/6000's POWER2 processor and Micro Channel bus are incompatible with the ANS's PowerPC CPU and PCI bus. During the development of the product, Apple tested alpha versions of Novell NetWare for PowerPC . Around the same time the hardware changed, the NetWare project ceased to be updated and later

13485-526: The Notebook". With the Microsoft deal expiring, Apple also replaced Internet Explorer with its new browser, Safari . The first Mac Mini was intended to be assembled in the U.S., but domestic manufacturers were slow and had insufficient quality processes, leading Apple to Taiwanese manufacturer Foxconn . The affordably priced Mac Mini desktop was introduced at Macworld 2005, alongside the introduction of

13640-442: The PCI bus, ANS parts ways with the PM9500 in a few ways. The ANS has two 53C825A SCSI chips with support for Fast & Wide SCSI operations, which are not present in the PM9500. These each appear as a separate PCI device on the PCI bus. The ANS also adds a Cirrus Logic 54M30 video controller as an additional PCI device. In all the ANS has three PCI devices which the PM9500 lacks. The ANS's PCI slots are also organized differently. On

13795-421: The PM9500, Grand Central and the first three PCI slots are supported by Bandit 1. The remaining three PCI slots are supported by Bandit 2. On the ANS, Grand Central, the two 53C825A SCSI chips, the 54M30 video controller and the upper two PCI slots are supported by Bandit 1. The remaining four PCI slots are supported by Bandit 2. Some may find it interesting that this (six devices supported by Bandit 1) confirms that

13950-455: The PM9500. However, the memory structure is the same with two banks of DIMM slots and support for memory interleaving when corresponding slots in different banks contain identical memory DIMMs. The ANS does have eight memory DIMM slots instead of the PM9500's twelve, but other Hammerhead-based machines such as the PM8500 also carry only eight memory DIMM slots. On the PCI bus, as mentioned above,

14105-524: The Performa 5200 as the worst Mac of all-time. The 603 found widespread use in different embedded appliances. The performance issues of the 603 were addressed in the PowerPC 603e . The L1 cache was enlarged and enhanced to 16 KB four-way set-associative data and instruction caches. The clock speed of the processors was doubled too, reaching 200 MHz. Shrinking the fabrication process to 350 nm allowed for speeds of up to 300 MHz. This part

14260-649: The PowerPC 601 in 1993, and the second generation soon followed with the PowerPC 603, PowerPC 604 and the 64-bit PowerPC 620. The PowerPC 601 was the first generation of microprocessors to support the basic 32-bit PowerPC instruction set . The design effort started in earnest in mid-1991 and the first prototype chips were available in October 1992. The first 601 processors were introduced in an IBM RS/6000 workstation in October 1993 (alongside its more powerful multichip cousin IBM POWER2 line of processors) and

14415-630: The PowerPC 603e as the main processor. The 603e processors also power all 66 satellites in the Iridium satellite phone fleet. The satellites each contain seven Motorola/Freescale PowerPC 603e processors running at roughly 200 MHz each. A custom 603e processor is also used in the Mark 54 Lightweight Torpedo . The PowerPC 603e core, renamed G2 by Freescale , is the basis for many embedded PowerQUICC II processors, and, as such, it keeps on being developed. Freescale's PowerQUICC II SoC processors bear

14570-400: The ability to drag and drop files, double-click to launch applications, and move or resize windows by clicking and dragging instead of going through a menu. However, hampered by its high price of $ 9,995 (equivalent to $ 33,000 in 2023) and lack of available software, the Lisa was commercially unsuccessful. Parallel to the Lisa's development, a skunkworks team at Apple was working on

14725-410: The company newsletter. The next year you'd come back and there would be thirty Macintoshes. The year after that, three hundred." In late 1985, Bill Atkinson, one of the few remaining employees to have been on the original Macintosh team, proposed that Apple create a Dynabook , Alan Kay's concept for a tablet computer that stores and organizes knowledge. Sculley rebuffed him, so he adapted the idea into

14880-526: The company's profit margins, and Macintoshes were priced far above entry-level MS-DOS compatible computers. Steven Levy said that though Macintoshes were superior, the cheapest Mac cost almost twice as much as the cheapest IBM PC compatible. Sculley also resisted licensing the Mac OS to competing hardware vendors, who could have undercut Apple on pricing and jeopardized its hardware sales, as IBM PC compatibles had done to IBM. These early strategic steps caused

15035-569: The company, he launched the Think different ad campaign, positioning the Mac as the best computer for "creative people who believe that one person can change the world". The campaign featured black-and-white photographs of luminaries like Albert Einstein , Gandhi , and Martin Luther King Jr. , with Jobs saying: "if they ever used a computer, it would have been a Mac". The ad campaign was critically acclaimed and won several awards, including

15190-585: The completely different unified I/O bus structure and SMP/ memory coherency support. New PowerPC changes, leveraging the basic RSC structure was very beneficial to reducing the uncertainty in chip area/floorplanning and timing analysis/tuning. Worth noting is that the 601 not only implemented substantial new key functions such as SMP, but it also acted as a bridge between the POWER and the future PowerPC processors to assist IBM and software developers in their transitions to PowerPC. From start of design to tape-out of

15345-599: The decisions to switch to fragile Butterfly keyboards, to make the Mac Pro non-expandable, and to remove USB-A, HDMI and the SD card slot from the MacBook Pro were criticized. The long-standing keyboard issue on MacBook Pros, Apple's abandonment of the Aperture professional photography app, and the lack of Mac Pro upgrades led to declining sales and a widespread belief that Apple was no longer committed to professional users. After several years without any significant updates to

15500-576: The design leveraged a number of key technologies and project management strategies. The 601 team leveraged much of the basic structure and portions of the IBM RISC Single Chip (RSC) processor, but also included support for the vast majority of the new PowerPC instructions not in the POWER instruction set . While nearly every portion of the RSC design was modified, and many design blocks were substantially modified or completely redesigned given

15655-602: The designation MPC82xx, and come in a variety of configurations reaching 450 MHz. The G2 name is also used as a retronym for the 603e and 604 processors to align with the G3, G4, and the G5. Freescale has enhanced the 603e core, calling it e300 , in the PowerQUICC II Pro embedded processors. Larger 32/32 KB L1 caches and other performance enhancing measures were added. Freescale's PowerQUICC II Pro SoC processors bear

15810-552: The designation MPC83xx, and come in a variety of configurations reaching speeds up to 667 MHz. The e300 is also the core of the MPC5200B SoC processor that is used in the small EFIKA computer. The PowerPC 604 was introduced in December 1994 alongside the 603 and was designed as a high-performance chip for workstations and entry-level servers and as such had support for symmetric multiprocessing in hardware. The 604

15965-497: The die had an area of 311 mm . It operated at clock rates between 120 and 150 MHz, and drew 30 W at 133 MHz. A later model was built using a 0.35 μm process, enabling it to reach 200 MHz. The 620 was similar to the 604. It has a five-stage pipeline, same support for symmetric multiprocessing and the same number of execution units; a load/store unit, a branch unit, an FPU, and three integer units. With larger 32 KB instruction and data caches, support for

16120-471: The dual "Bandit" bus controllers, the proprietary floppy format, and possibly the CD-ROM. UW-SCSI hard disks are seldom an issue and Apple even released an U-SCSI (but narrow) hard disk installation kit for the ANS even though an ANS is normally only equipped with UW-SCSI disks. As of 2005, most Apple Network Servers had been removed from service and most had been returned to Apple or sold on the secondary market, either factory remanufactured or as-is, or sent to

16275-501: The early name for the Apache series 64-bit PowerPC processors, designed by IBM based on the "Amazon" PowerPC-AS instruction set. They were later renamed " RS64 ". The designation "PowerPC 625" was never used for the final processors. "PowerPC 630" was the early name for the high end 64-bit PowerPC processor, designed by IBM to unify the POWER and PowerPC instruction sets. It was later renamed " POWER3 ", probably to distinguish it from

16430-502: The era, the ANS uses a VGA connector for the on-board video; an adapter for Apple displays was included. A unique aspect of the Apple Network Servers is their case: It is fully lockable and extremely accessible, it features a small LCD for diagnostics, and its front has seven device slots, with a CD-ROM and one hard drive mounted in them in the standard configuration. Additional hot-swappable SCSI hard drive modules or

16585-452: The first 601 prototype was just 12 months in order to push hard to establish PowerPC on the market early. In order to help the effort to rapidly incorporate the 88110 bus architecture to the 601 for the benefit of the alliance and its customers, Motorola management provided not only the 88110 bus architecture specifications, but also a handful of 88110 bus-literate designers to help with the 60x bus logic implementation and verification. Given

16740-609: The first Apple Power Macintoshes on March 14, 1994. The 601 was the first advanced single-chip implementation of the POWER/PowerPC architecture designed on a crash schedule to establish PowerPC in the marketplace and cement the AIM alliance. In order to achieve an extremely aggressive schedule while including substantially new functionality (such as substantial performance enhancements, new instructions and importantly POWER/PowerPC's first symmetric multiprocessing (SMP) implementation)

16895-433: The fourth generation PowerPC even though the architectural differences between "G3" and "G4" was small. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. The " PowerPC 615 " is a PowerPC processor announced by IBM in 1994, but which never reached mass production . Its main feature was to incorporate an x86 core on die, thus making

17050-444: The highest-resolution all-in-one desktop computer. The MacBook was reintroduced in 2015, with a completely redesigned aluminum unibody chassis, a 12-inch Retina display, a fanless low-power Intel Core M processor, a much smaller logic board, a new Butterfly keyboard, a single USB-C port, and a solid-state Force Touch trackpad with pressure sensitivity. It was praised for its portability, but criticized for its lack of performance,

17205-467: The iMac a radical and futuristic design, meant to make the product less intimidating. Its oblong case is made of translucent plastic in Bondi blue , later revised with many colors. Ive added a handle on the back to make the computer more approachable. Jobs declared the iMac would be "legacy-free", succeeding ADB and SCSI with an infrared port and cutting-edge USB ports. Though USB had industry backing, it

17360-469: The last. Apple acquired NeXT on December 20, 1996, returning its co-founder, Steve Jobs. NeXT had developed the mature NeXTSTEP operating system with strong multimedia and Internet capabilities. NeXTSTEP was also popular among programmers, financial firms, and academia for its object-oriented programming tools for rapid application development . In an eagerly anticipated speech at the January 1997 Macworld trade show, Steve Jobs previewed Rhapsody ,

17515-729: The late 1970s, the Apple II became one of the most popular computers, especially in education. After IBM introduced the IBM PC in 1981, its sales surpassed the Apple II. In response, Apple introduced the Lisa in 1983. The Lisa's graphical user interface was inspired by strategically licensed demonstrations of the Xerox Star . Lisa surpassed the Star with intuitive direct manipulation , like

17670-413: The machine's low performance, single floppy disk drive requiring frequent disk swapping, and initial lack of applications. Author Douglas Adams said: "But what I (and I think everybody else who bought the machine in the early days) fell in love with was not the machine itself, which was ridiculously slow and underpowered, but a romantic idea of the machine. And that romantic idea had to sustain me through

17825-444: The machine, they would risk progressively damaging the cable responsible for the display backlight , which was too short. The $ 6 cable was soldered to the screen, requiring a $ 700 repair. Senior Vice President of Industrial Design Jony Ive continued to guide product designs towards simplicity and minimalism. Critics argued that he had begun to prioritize form over function, and was excessively focused on product thinness. His role in

17980-432: The many variants of the 601, 603, 604, G3 , G4 and Motorola/Freescale PowerQUICC processors. The chip was designed to suit a wide variety of applications and had support for external L2 cache and symmetric multiprocessing . It had four functional units, including a floating-point unit , an integer unit , a branch unit and a sequencer unit. The processor also included a memory management unit . The integer pipeline

18135-515: The marketing, engineering, and operations teams. The engineering team was led by the product design group, and Ive's design studio was the dominant voice throughout the development process. The next two Mac products in 1999, the Power Mac G3 (nicknamed "Blue and White") and the iBook , introduced industrial designs influenced by the iMac, incorporating colorful translucent plastic and carrying handles. The iBook introduced several innovations:

18290-496: The more expensive 603e while drawing less power. It had an in-order, five-stage pipeline with a single integer unit, a double-precision floating-point unit (FPU) and separate 16 KB instruction and 8 KB data caches. While the integer unit was a brand new design, the FPU was derived from the R4600 to save time. It was 69 mm small using a 0.5 μm fabrication process and drew just 1.2 W at 120 MHz. The 603q

18445-498: The need to use adapters to use most USB peripherals, and a high starting price of $ 1,299 (equivalent to $ 1,700 in 2023). In 2015, Apple started a service program to address a widespread GPU defect in the 15-inch 2011 MacBook Pro , which could cause graphical artifacts or prevent the machine from functioning entirely. The Touch Bar MacBook Pro was released in October 2016. It was the thinnest MacBook Pro ever made, replaced all ports with four Thunderbolt 3 (USB-C) ports, gained

18600-552: The other hand, many logic board components, especially the Open Firmware boot ROM, are similar to the "Tsunami" board used in the Power Macintosh 9500 and some Macintosh clones . While the circuit board layout of the Apple Network Server (ANS) may resemble RS/6000 systems, logically and physically it is almost identical to a Power Macintosh 9500 (PM9500), although running quite different firmware, and which

18755-429: The processor able to natively process both PowerPC and x86 instructions. An operating system running on PowerPC 615 could either choose to execute 32-bit or 64-bit PowerPC instructions, 32-bit x86 instructions or a mix of three. Mixing instructions would involve a context switch in the CPU with a small overhead. The only operating systems that supported the 615 were Minix and a special development version of OS/2 . It

18910-427: The product and giving an inside look into its creation. Apple took a new "multiple exclusives" approach regarding the press, giving "over one hundred interviews to journalists that lasted over six hours apiece", and introduced a new "Test Drive a Macintosh" campaign. Apple's brand, which established a "heartfelt connection with consumers", is cited as one of the keys to the Mac's success. After Steve Jobs's return to

19065-461: The product, Apple made modifications to the Power Macintosh 9500 logic board and ROM (locking out all Mac OS calls) and ported AIX to the new hardware. Whether related to the hardware change or by coincidence, Apple also abandoned its NetWare on PowerPC development (codename: Wormhole) at this time. The general logic board layout seems to suggest a close relationship with PowerPC-based RS/6000 systems by IBM , which also were designed to run AIX. On

19220-536: The projects' merit, this once-renegade project was actually endorsed by senior management following market pressures. In 1990 came the Macintosh LC and the more affordable Macintosh Classic , the first model under $ 1,000 (equivalent to $ 2,300 in 2023). Between 1984 and 1989, Apple had sold one million Macs, and another 10 million over the following five years. In 1991, the Macintosh Portable

19375-402: The realities of actually working on the 128K Mac." Most of the original Macintosh team left Apple, and some followed Jobs to found NeXT after he was forced out by CEO John Sculley . The first Macintosh nevertheless generated enthusiasm among buyers and some developers, who rushed to develop entirely new programs for the platform, including PageMaker , MORE , and Excel . Apple soon released

19530-514: The rumors, that such a decision made sense, as Intel was failing to make significant improvements to its processors, and could not compete with ARM chips on battery life. At WWDC 2020, Tim Cook announced that the Mac would be transitioning to Apple silicon chips, built upon an ARM architecture, over a two-year timeline. The Rosetta 2 translation layer was also introduced, enabling Apple silicon Macs to run Intel apps. On November 10, 2020, Apple announced their first system-on-a-chip designed for

19685-547: The smaller processor caches. As a result, Apple chose to only use the 603 in its low-cost desktop Performa line. This caused the delay of the Apple PowerBook 5300 and PowerBook Duo 2300 , as Apple chose to wait for a processor revision. Apple's use of the 603 in the Performa 5200 line led to the processor getting a poor reputation. Aside from the issue of 68K emulation performance, the Performa machines shipped with

19840-552: The standard M3 chip in a refreshed iMac and a new base model MacBook Pro. Reviewers lamented the base memory configuration of 8 GB on the standard M3 MacBook Pro. In March 2024, the MacBook Air was also updated to include the M3 chip. In October 2024, several Macs were announced with the M4 series of chips, including the iMac, a redesigned Mac Mini, and the MacBook Pro; all of which included 16 GB of memory as standard. The MacBook Air

19995-490: The successful 1989 release of the Macintosh II , which appealed to power users and gave the lineup momentum. However, Gassée's "no-compromise" approach foiled Apple's first laptop , the Macintosh Portable , which has many uncommon power user features, but is almost as heavy as the original Macintosh at twice its price. Soon after its launch, Gassée was fired. Since the Mac's debut, Sculley had opposed lowering

20150-586: The unreliable Butterfly keyboard with a redesigned scissor-switch Magic Keyboard. On the MacBook Pros, the Touch Bar and Touch ID were made standard, and the Esc key was detached from the Touch Bar and returned to being a physical key. At WWDC 2019, Apple unveiled a new Mac Pro with a larger case design that allows for hardware expandability, and introduced a new expansion module system (MPX) for modules such as

20305-407: Was 121 mm large and contained 2.8 million transistors. The 601 has a 32 KB unified L1 cache , a capacity that was considered large at the time for an on-chip cache. Thanks partly to the large cache it was considered a high performance processor in its segment, outperforming the competing Intel Pentium . The PowerPC 601 was used in the first Power Macintosh computers from Apple , and in

20460-404: Was 148 mm or 96 mm large, manufactured by Motorola and IBM respectively, drawing 16–18 W at 233 MHz. It operated at speeds between 166 and 233 MHz and supported a memory bus up to 66 MHz. The PowerPC 604ev , 604r or "Mach 5" was introduced in August 1997 and was essentially a 604e fabricated by IBM and Motorola with a newer process, reaching higher speeds with

20615-401: Was 330 mm large and manufactured by IBM on a 0.35 μm process. It was pin compatible with Intel 's Pentium processors and comparable in speed. The processor was introduced only as a prototype and the program was killed in part by the fact that Microsoft never supported the processor. Engineers working on the PowerPC 615 would later find their way to Transmeta , where they worked on

20770-403: Was abandoned. Apple also tested and produced limited numbers of ROM SIMMs which supported Windows NT for PowerPC on the Network Server 500 and 700. As an alternative to AIX it is possible, though complicated, to install PowerPC Linux or NetBSD on the ANS. It is possible, with prototype Macintosh ROMs, to boot an Apple Network Server 500 or 700 into Mac OS 7.5 or later, however Ethernet support

20925-413: Was able to gradually take control of the project due to Wozniak's temporary absence after an airplane crash . Under Jobs, the Mac grew to resemble the Lisa, with a mouse and a more intuitive graphical interface, at a quarter of the Lisa's price. Upon its January 1984 launch, the first Macintosh was described as "revolutionary" by The New York Times . Sales initially met projections, but dropped due to

21080-406: Was also upgraded with 16 GB for the same price. The original Macintosh was marketed at Super Bowl XVIII with the highly acclaimed "1984" ad, directed by Ridley Scott . The ad alluded to George Orwell 's novel Nineteen Eighty-Four , and symbolized Apple's desire to "rescue" humanity from the conformity of computer industry giant IBM . The ad is now considered a "watershed event" and

21235-492: Was an advanced design for its day, being one of the first microprocessors to offer dual issue (up to three with branch folding) and out-of-order execution combined with low power consumption of 2.2 W and a small die of 85 mm . It was designed to be a low cost, low power processor for portable applications. One of the main features was power saving functions (doze, nap and sleep mode) that could dramatically reduce power requirements, drawing only 2 mW in sleep mode. The 603 has

21390-434: Was designed for Motorola, but they withdrew from the contract before the 603q went into full production. As a result, the 603q was canceled as QED could not continue to market the processor since they lacked a PowerPC license of their own. "PowerPC 613" seems to be a name Motorola had given a third generation PowerPC. It supposedly was renamed " PowerPC 750 " in response to Exponential Technology 's x704 processor that

21545-453: Was designed to outgun the 604 by a wide margin. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. Similar to PowerPC 613, the "PowerPC 614" might have been a name given by Motorola to a third generation PowerPC, and later renamed by the same reason as 613. It's been suggested that the part was renamed " PowerPC 7400 ", and Motorola even bumped it to

21700-533: Was four stages long, the branch pipeline two stages long, the memory pipeline five stages long, and the floating-point pipeline six stages long. First launched in IBM systems in the fall of 1993, it was marketed by IBM as the PPC601 and by Motorola as the MPC601. It operated at speeds ranging from 50 to 80 MHz. It was fabricated using a 0.6 μm CMOS process with four levels of aluminum interconnect . The die

21855-415: Was introduced alongside the Studio Display , and was meant to replace the 27-inch iMac, which was discontinued on the same day. At WWDC 2022 , Apple announced an updated MacBook Air based on a new M2 chip. It incorporates several changes from the 14-inch MacBook Pro, such as a flat, slab-shaped design, full-sized function keys, MagSafe charging, and a Liquid Retina display, with rounded corners and

22010-404: Was introduced in July 1996 and added a condition register unit and separate 32 KB data and instruction L1 caches among other changes to its memory subsystem and branch prediction unit, resulting in a 25% performance increase compared to its predecessor. It had 5.1 million transistors and was manufactured by IBM and Motorola on a 0.35 μm CMOS process with five levels of interconnect. The die

22165-583: Was named as his successor. Cook's first keynote address launched iCloud , moving the digital hub from the Mac to the cloud. In 2012, the MacBook Pro was refreshed with a Retina display, and the iMac was slimmed and lost its SuperDrive . During Cook's first few years as CEO, Apple fought media criticisms that it could no longer innovate without Jobs. In 2013, Apple introduced a new cylindrical Mac Pro , with marketing chief Phil Schiller exclaiming "Can't innovate anymore, my ass!". The new model had

22320-488: Was not complete. No reliable sources for the procedure or requirements exist. Not only is the Ethernet different, but the display interface is as well. Using an Apple-branded, but DEC "Tulip" Ethernet card and a display card from a 9500 goes a long way towards achieving Mac OS capability but even this is not assured. Yellowdog Linux 2.x or 3.x is more assured, and NetBSD 1.5.x might be even better. Major issues remain, such as

22475-507: Was publicly unveiled in January 2000, introducing the modern Aqua graphical user interface, and a far more stable Unix foundation, with memory protection and preemptive multitasking . Blue Box became the Classic environment , and Yellow Box was renamed Cocoa . Following a public beta , the first version of Mac OS X, version 10.0 Cheetah , was released in March 2001. In 1999, Apple launched its new "digital lifestyle" strategy of which

22630-450: Was ready to abandon Microsoft Office for Mac, which would have slashed any remaining business appeal the Mac had. Gil Amelio , Spindler's successor, failed to negotiate a deal with Gates. In 1996, Spindler was succeeded by Amelio, who searched for an established operating system to acquire or license for the foundation of a new Macintosh operating system. He considered BeOS , Solaris, Windows NT, and NeXT's NeXTSTEP , eventually choosing

22785-459: Was replaced with the smaller and lighter PowerBook 100 , the first laptop with a palm rest and trackball in front of the keyboard. The PowerBook brought $ 1 billion of revenue within one year, and became a status symbol. By then, the Macintosh represented 10% to 15% of the personal computer market. Fearing a decline in market share, Sculley co-founded the AIM alliance with IBM and Motorola to create

22940-529: Was revealed at WWDC 2017, featuring updated Intel Xeon W processors and Radeon Pro Vega graphics. In 2018, Apple released a redesigned MacBook Air with a Retina display, Butterfly keyboard, Force Touch trackpad, and Thunderbolt 3 USB-C ports. The Butterfly keyboard went through three revisions, incorporating silicone gaskets in the key mechanism to prevent keys from being jammed by dust or other particles. However, many users continued to experience reliability issues with these keyboards, leading Apple to launch

23095-452: Was revealed, featuring the M1 chip, seven new colors, thinner white bezels, a higher-resolution 1080p webcam, and an enclosure made entirely from recycled aluminum. On October 18, 2021, Apple announced new 14-inch and 16-inch MacBook Pros , featuring the more powerful M1 Pro and M1 Max chips, a bezel-less mini-LED 120 Hz ProMotion display, and the return of MagSafe and HDMI ports, and

23250-479: Was stagnant. The Mac was no longer competitive, and its sales entered a tailspin. Corporations abandoned Macintosh in droves, replacing it with cheaper and more technically sophisticated Windows NT machines for which far more applications and peripherals existed. Even some Apple loyalists saw no future for the Macintosh. Once the world's second largest computer vendor after IBM, Apple's market share declined precipitously from 9.4% in 1993 to 3.1% in 1997. Bill Gates

23405-466: Was still absent from most PCs and USB 1.1 was only standardized one month after the iMac's release. He also controversially removed the floppy disk drive and replaced it with a CD drive. The iMac was unveiled in May 1998, and released in August. It was an immediate commercial success and became the fastest-selling computer in Apple's history, with 800,000 units sold before the year ended. Vindicating Jobs on

23560-519: Was the first family of PowerPC processors built. They were designed at the Somerset facility in Austin, Texas , jointly funded and staffed by engineers from IBM and Motorola as a part of the AIM alliance . Somerset was opened in 1992 and its goal was to make the first PowerPC processor and then keep designing general purpose PowerPC processors for personal computers . The first incarnation became

23715-432: Was the first implementation of the entire 64-bit PowerPC architecture. It was a second generation PowerPC alongside the 603 and 604, but geared towards the high-end workstation and server market. It was powerful on paper and was initially supposed to be launched alongside its brethren but it was delayed until 1997. When it did arrive, the performance was comparably poor and the considerably cheaper 604e surpassed it. The 620

23870-441: Was therefore never produced in large quantities and found very little use. The sole user of PowerPC 620 was Groupe Bull in its Escala UNIX machines, but they didn't deliver any large numbers. IBM, which intended to use it in workstations and servers, decided to wait for the even more powerful RS64 and POWER3 64-bit processors instead. The 620 was produced by Motorola in a 0.5 μm process. It had 6.9 million transistors and

24025-730: Was used extensively in Apple 's high-end systems and was also used in Macintosh clones , IBM's low-end RS/6000 servers and workstations, Amiga accelerator boards, and as an embedded CPU for telecom applications. The 604 is a superscalar processor capable of issuing four instructions simultaneously. The 604 has a six-stage pipeline and six execution units that can work in parallel, finishing up to six instructions every cycle. Two simple and one complex integer units , one floating-point unit , one branch-processing unit managing out-of-order execution and one load/store unit. It has separate 16 KB data and instruction L1 caches. The external interface
