This will be the first time in the 36-year history of the Mac that Apple-designed processors will power these machines. It has changed chips only two other times. In the early 1990s, Apple switched from Motorola processors to PowerPC. At WWDC in 2005, Steve Jobs announced a move from PowerPC to Intel, and Apple rolled out those first Intel-based Macs in January 2006. Like it did then, the company plans to eventually transition the entire Mac lineup to its Arm-based processors, including the priciest desktop computers, the people said.
Apple has had the best processors for consumer facing products for years, so this is a long time coming. There will be some issues, and one that came to mind was running Windows in a virtualized space or Bootcamp. However, the need most had to run Windows is lessening as more and more and services have moved some their offerings to the cloud while being accessible in the browser. There will always be outliers on the margins, but any pressure on Intel is a good thing at this point.
