Between October 2016 and August 2020, Intel-based Macs with Apple-designed ARM co-processors were released. Apple has designed its own custom ARM chips since 2009, which it has since used in its iPhone, iPad, iPod, Apple TV, Apple Watch, AirPods, Beats and HomePod products. The first Apple products with an ARM system on a chip were the 1993 Newton personal digital assistant, the 2001 iPod, and the 2007 iPhone. A partnership was established with Acorn Computers, and VLSI in 1990, and work began on a chip for small devices. The ATG thought it might replace the MOS 6502 of the Apple II range or the 68000 of the original Macintosh, or become the basis of a tablet device, under Paul Gavarini and Tom Pittard, in a project labelled Möbius. The genesis of the third switch began in 1985, when Acorn's ARM architecture was spotted by Apple's Advanced Technology Group, an internal research laboratory. Supported 64-bit Intel systems can still boot the latest versions of macOS.

In 2011, Mac OS X Lion dropped support for Macs with 32-bit processors in 2019, macOS Catalina dropped support for 32-bit Intel apps. It switched again, starting in 2005, to Intel 32-bit and 64-bit x86. In the early 1990s, Apple evaluated several possibilities, then switched to the PowerPC family it co-developed with IBM and Motorola. The first Macintoshes, introduced in 1984, were based on the Motorola 68000 architecture.

Background A first-generation MacBook Pro from 2006, one of the first line of Mac computers to feature an Intel processor instead of a PowerPC processor The first was from the Motorola 68000 series to PowerPC chips in 1994, and the second was from PowerPC to Intel processors using the x86 architecture in 2005–2006. The transition was the third time Apple had switched the Macintosh to a new instruction set architecture. The first Macs with Apple-designed systems on a chip were released that November the last, the Mac Pro, was released in June 2023, completing the transition in three years. The Mac transition to Apple silicon was the process of changing the central processing units (CPUs) of Apple Inc.'s line of Mac computers from Intel's x86-64 processors to Apple-designed systems on a chip that use the ARM64 architecture.Īpple CEO Tim Cook announced a "two-year transition plan" to Apple silicon on June 22, 2020.
