Apple’s forthcoming macOS 27 doesn’t run on Intel Macs at all, and that’s just the beginning of a timeline that will complete a years-long transition to Apple Silicon. Here’s what to expect, and when.

Running Intel apps on Macs will soon be a thing of the past

Running Intel apps on Macs will soon be a thing of the past
When Apple unveiled macOS 27 during its WWDC 2026 opening keynote, it put into motion its previously announced plan for the end of Intel Macs. Not only will the update not support any Intel Macs, but it also removes the Rosetta 2 translation layer that allows Intel apps to run on other Macs, too.
Apple announced the transition away from Intel chips in 2020, choosing to use its own in-house silicon instead. Now, six years later, it’s getting ready to complete that transition, and app developers are on notice.
