In 2004 and the first half of 2005, the Internet was swirling with rumors that Apple would move to Intel processors to power its Mac line, due to speed and heat issues with IBM’s PowerPC chips, which had powered the Mac for years
At WWDC 2005, the company took the wraps off of its plan, which included a “Developer Transition Kit” that allowed developers to test their code on an Intel machine.
Apple also announced “Rosetta,” a software layer that allowed most PPC-based applications to run on Intel Macs seamlessly and quickly.
At Macworld in 2006 — just six months later — Apple introduced the Intel iMac and the MacBook Pro. The entire product line was moved to Intel processors in a mere 14 months after the announcement.
