Rumors of Apple shifting Macintosh to custom-designed ARM processors began circulating in 2011, when ''SemiAccurate'' predicted it would happen by mid-2013. In 2014, ''MacRumors'' reported that Apple was testing an ARM-based Mac prototype with a large Magic Trackpad.

Transition process


2020

Apple announced its plans to shift the Macintosh platform to Apple silicon in a series of WWDC presentations in June 2020. The entire transition of the Macintosh product line is expected to take "about two years", with the first ARM-based Macs released by the end of 2020. Similar language was used during Apple's 2005–2006 transition to Intel, which actually took about one year. All Apple apps included with

Lauren Giret remarked that Apple might "succeed where Microsoft has failed" due to Apple's "tight integration" of hardware and software, and a vast collection of applications that can already run on the new platform. When systems containing M1 processors were released, they received near-universal acclaim for their high speed and low energy consumption.
