The Mac transition to Apple silicon was the process of switching the central processing units (CPUs) of Apple's line of Mac computers from Intel's x86-64 processors to Apple-designed Apple silicon ARM64 processors.
Apple CEO Tim Cook announced a "two-year transition plan" to Apple silicon on June 22, 2020.[1] The first Macs with Apple-designed systems on a chip were released that November;[2] the last, the Mac Pro, was released in June 2023, completing the transition in three years.
The transition was the third time Apple had switched the Macintosh to a new instruction set architecture. 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 2006.[3][4]
