Apple officials also said in 2003 they planned to release a PowerBook with a G5 processor, but such a product never materialized. In 2004's WWDC keynote address, Jobs addressed the broken promise, saying IBM had trouble moving to a fabrication process lower than the 90 nm process. ĭespite promise of a 3 GHz Power Mac G5 within 12 months of the Power Mac G5's release, such a product was never released. At the time, the Power Mac G5 was the first personal computer to feature a 64-bit processor. Ī PowerPC 970FX processor, which was used in a number of Apple computers featuring PowerPC G5 processors.īy the time Apple announced the transition to Intel processors, Apple had been using PowerPC processors in its product line for 11 years.ĭuring 2003's WWDC keynote address, Jobs unveiled a Power Mac that features a processor from IBM's PowerPC G5 product line. In 2020, 15 years following the announcement to transition to Intel processors, Apple announced a transition of the Macintosh to Apple silicon, which are ARM-based processors developed in-house. It is also the last Mac OS X version that supports PowerPC-based applications, as Mac OS X v10.7 'Lion' dropped support for Rosetta. Īpple released Mac OS X v10.6 'Snow Leopard' on Augas Intel-only, removing support for the PowerPC architecture. The Xserve servers were available in December 2006. The first-generation Intel-based Macintoshes were released in January 2006 with Mac OS X 10.4.4 Tiger, and Steve Jobs announced the last models to switch in August 2006, the Mac Pro available immediately and with the Intel Xserve available by October 2006. Īpple's initial press release indicated the transition would begin by June 2006, and finish by the end of 2007, but it actually proceeded much more quickly. The first was the switch from the Mac's original Motorola 68000 series architecture to the then-new PowerPC platform in 1994. Īt the time, the transition marked the second time Apple migrated its personal computer product line from one processor instruction set architecture to another. The transition became public knowledge at the 2005 Worldwide Developers Conference (WWDC), when then Apple CEO Steve Jobs made the announcement to transition away from the use of PowerPC microprocessors supplied by Freescale (formerly Motorola) and IBM.

The Mac transition to Intel processors was the process of changing the central processing unit (CPU) of Apple Inc.'s line of Mac computers, as well as its server offerings at the time, from PowerPC to Intel x86 processors.
