Definition: ARM Mac

An ARM-based Mac computer. In late 2020, Apple will begin switching its Mac computer line from Intel CPUs to ARM CPUs. Because iPhones and iPads are ARM based, switching the Mac to ARM chips enables development on one hardware platform across Apple's entire line. Introduced in 1984 the first Macintosh line ran on Motorola CPUs. Apple switched its CPUs to PowerPC in 1994 and to Intel in 2006. See PowerPC and Intel Mac.
