He promised a 3 GHz Power Mac G5 within 12 months, but never released such a product. Background Ī PowerPC 970FX processor, which was used in a number of Apple computers featuring PowerPC G5 processorsĪpple had been using PowerPC processors in its products for 11 years when the move to Intel processors was announced.Īt 2003's WWDC keynote address, Jobs unveiled a Power Mac with a processor from IBM's PowerPC G5 product line, the first personal computer to feature a 64-bit processor. In 2020, Apple announced that it would shift its Mac line to Apple silicon, which are ARM-based processors developed in-house. Mac OS X Lion (version 10.7) dropped support altogether. The final version to run applications written for PowerPC chips, using the Rosetta binary translator, was 2009's Snow Leopard (version 10.6). The final version of Apple's Mac OS X that ran on PowerPC chips was 2007's Leopard (version 10.5), released in October 2007.
In August, Jobs announced the last models to switch, with the Mac Pro available immediately and the Intel Xserve available by October (it actually shipped in December). The first-generation Intel-based Macintoshes were released in January 2006 with Mac OS X 10.4.4 Tiger. Īpple's initial press release said the move would begin by June 2006 and finish by the end of 2007, but it actually proceeded much more quickly. The first was in 1994, when Apple discarded the Mac's original Motorola 68000 series architecture in favor of the then-new PowerPC platform. This was the second time Apple changed the processor instruction set architecture of its personal computers. The change was announced at the 2005 Worldwide Developers Conference (WWDC) by then-Apple CEO Steve Jobs, who said Apple would gradually stop using PowerPC microprocessors supplied by Freescale (formerly Motorola) and IBM. Apple transitioned the CPUs of their Mac and Xserve computers from PowerPC to the x86 architecture from Intel.
