The Apple Intel transition was the process of changing the CPU of Macintosh computers from PowerPC processors to Intel x86 processors. The transition became public knowledge at the 2005 Worldwide Developers Conference (WWDC), when Apple Computer CEO Steve Jobs made the historic announcement that the company would make a transition from the use of PowerPC microprocessors supplied by Freescale (formerly Motorola) and IBM in its Macintosh computers, to processors designed and manufactured by Intel, a chief supplier for most of Apple's competitors.

Apple'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 generation Intel-based Macintoshes were released in January 2006, and Steve Jobs announced the last models to switch in August 2006, with the Mac Pro available immediately and with the Intel Xserve available by October 2006. The Xserve servers were available in December 2006.
