Here is a bit of history of the migration to Intel based CPUs. "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 with Mac OS X 10.4.4 Tiger, 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.[2] The Xserve servers were available in December 2006.[3]" https://en.wikipedia.org/wiki/Apple%27s_transition_to_Intel_processors https://en.wikipedia.org/wiki/Apple%27s_transition_to_Intel_...
