PowerPC to Intel Transition

Main Article: PowerPC to Intel Transition

At WWDC 2005, Apple announced its decision to gradually transition its computer lines over to Intel processors over the course of two years, with the entire transition process to be complete by the end of 2007.

The transition officially began at Macworld San Francisco in January 2006, where the professional PowerBook laptop line and consumer iMac desktop line transitioned over to Intel Core Duo processors. At the same time, the name "Power" in "PowerBook", which was widely believed to be a name associated with its processors, was changed to MacBook Pro.

This was followed in February 28, 2006 with the transitioning of the Mac Mini line over to Intel processors, and on May 16th, 2006, with the iBook consumer laptop line transitioning over to Intel processors, and renamed MacBook.

On August 7th, 2006, Apple declared "Transition Complete" as its professional desktop line, PowerMac, and its XServe server lines transitioned over to Intel processors. Following the custom of dropping the term "Power" and having the term "Mac" on all computer names, PowerMac was subsequently renamed Mac Pro.

In all, the transition took place over the course of one year, and was completed more than one year ahead of schedule.
