Summary

Apple is ending Rosetta 2 compatibility with the expected release of macOS 28 in fall 2027, which will break over 18,800 Intel-only Mac apps that have not been compiled for Apple Silicon. macOS 26.5 (released May 2026) now displays a system warning to users each time they open an Intel-based app, alerting them that support will be discontinued. This marks the final phase of Apple's six-year transition from Intel processors to its own Apple Silicon chips, impacting legacy enterprise software, specialist audio plugins, and other applications that developers have not updated.

With macOS 26.5 — the current shipping version of macOS, released May 11, 2026 — every Mac user who opens an Intel-only app now sees a system warning stating it will stop working in a future macOS release.

That future is fall 2027, when macOS 28 is expected to cut off Rosetta 2 compatibility for virtually all Intel-based software.

A community-tracked database of Intel-only Mac apps already counts more than 18,800 titles — ranging from legacy enterprise software to specialist audio plugins — that have not been compiled for Apple Silicon.
