The initial versions of the M1 chips contain an architectural defect that permits sandboxed applications to exchange data, violating the security model, an issue that has been described as "mostly harmless". The M1 has four high-performance "Firestorm" and four energy-efficient "Icestorm" cores , first seen on
980-704: The MagSafe connector to third parties, but manufacturers have devised a workaround: their MagSafe-compatible products use the actual connector from Apple's AC adapter, grafted onto their own products. Since this uses an actual Apple product, purchased legally, manufacturers believe that no licensing agreements are needed (a principle referred to as the first sale doctrine ) and no patent was violated. However, in 2010 Apple still sued one such manufacturer, Sanho Corporation for selling its very popular HyperMac battery extension products which Apple claimed violated their patents. Sanho has since ceased to sell their connector cable for
