During WWDC 2025, Apple revealed that macOS 26 Tahoe would be the final major macOS version for Intel-based Macs.
macOS 27 will be compatible with Apple silicon Macs only, meaning that you will need a Mac with an M-series chip or a MacBook Neo with an A18 Pro chip in order to install the software update. Apple will unveil macOS 27 during its WWDC 2026 keynote this Monday, June 8, and the update should be widely released in September.
Intel-based Macs that can run macOS Tahoe but will not be compatible with macOS 27:
macOS 27's exact compatibility with Apple silicon Macs remains to be seen, but presumably the update will support all Macs with an M1 chip or newer.
macOS 27 will still be able to run Intel apps, as it will be the final major macOS release to include Apple's full Rosetta translation layer.
"Rosetta was designed to make the transition to Apple silicon easier, and we plan to make it available for the next two major macOS releases – through macOS 27 – as a general-purpose tool for Intel apps to help developers complete the migration of their apps," said Apple. "Beyond this timeframe, we will keep a subset of Rosetta functionality aimed at supporting older unmaintained gaming titles, that rely on Intel-based frameworks."
