Rumors of Apple shifting Macs from Intel to in-house ARM processors used by iOS devices began circulating as early as 2011,<ref name="SemiAccurate">{{Cite web |last=Demerjian |first=Charlie |date=May 5, 2011 |title=Apple dumps Intel from laptop lines |url=https://semiaccurate.com/2011/05/05/apple-dumps-intel-from-laptop-lines |access-date=June 25, 2020 |website=SemiAccurate |publisher=Stone Arch Networking Services, Inc. |archive-date=May 17, 2022 |archive-url=https://web.archive.org/web/20220517065123/https://semiaccurate.com/2011/05/05/apple-dumps-intel-from-laptop-lines/ |url-status=live }}</ref> and ebbed and flowed throughout the 2010s.<ref>{{Cite web |title=Apple Testing ARM Based Mac Prototypes with Large Magic Trackpad? |url=https://www.macrumors.com/2014/05/25/arm-mac-magic-trackpad |access-date=2020-06-22 |website=MacRumors |date=May 25, 2014 |language=en |archive-date=September 15, 2022 |archive-url=https://web.archive.org/web/20220915162849/https://www.macrumors.com/2014/05/25/arm-mac-magic-trackpad/ |url-status=live }}</ref> Rumors intensified in 2020, when numerous reports announced that the company would announce its shift to its custom processors at WWDC.<ref>{{Cite web |title=ARM Macs: Expected at WWDC 2020, What We Know |url=https://www.macrumors.com/guide/arm-macs |access-date=2020-06-22 |website=MacRumors |language=en |archive-date=June 25, 2020 |archive-url=https://web.archive.org/web/20200625004016/https://www.macrumors.com/guide/arm-macs/ |url-status=live }}</ref>

Apple officially announced its shift to [[Apple silicon|processors designed in-house]] on June 22, 2020, at WWDC 2020, with the transition planned to last for approximately two years.<ref>{{Cite press release |title=Apple announces Mac transition to Apple silicon |publisher=Apple Inc. |url=https://www.apple.com/newsroom/2020/06/apple-announces-mac-transition-to-apple-silicon |access-date=2020-06-22 |archive-date=June 22, 2020 |archive-url=https://web.archive.org/web/20200622185215/https://www.apple.com/newsroom/2020/06/apple-announces-mac-transition-to-apple-silicon |url-status=live }}</ref> The first release of macOS to support ARM was [[macOS Big Sur]]. Big Sur and later versions support [[Universal binary#Universal 2|Universal 2 binaries]], which are applications consisting of both Intel ([[x86-64]]) and Apple silicon ([[AArch64]]) binaries; when launched, only the appropriate binary is run. Additionally, Intel binaries can be run on Apple silicon-based Macs using the [[Rosetta 2]] [[binary translation]] software. The transition was completed at [[WWDC 2023]] with the announce of the Apple silicon [[Mac Pro]], ending the transition in 3 years, slightly behind schedule.

The change in processor architecture allows Macs with ARM processors to be able to run iOS and iPadOS apps natively.<ref name="Engadget1">{{Cite news |last=Lee |first=Nicole |date=June 22, 2020 |title=iOS apps will run natively on ARM-powered Macs |work=[[Engadget]] |url=https://www.engadget.com/ios-apps-arm-powered-macs-192046502.html |access-date=June 23, 2020 |archive-date=December 8, 2020 |archive-url=https://web.archive.org/web/20201208172634/https://www.engadget.com/ios-apps-arm-powered-macs-192046502.html |url-status=live }}</ref>
