Overview
- In macOS Tahoe 26.4 developer beta, launching an Intel‑only app now triggers a popup explaining the app will stop working once Rosetta 2 support is removed.
- Apple will keep Rosetta 2 fully available through macOS 27, then largely discontinue it in macOS 28 with a narrow fallback kept for select legacy titles.
- macOS 26 is the final major release for Intel‑based Macs, with Apple planning three years of security updates for those machines after this version.
- Apple says limited Rosetta capability will persist beyond macOS 27 for older unmaintained games and certain Intel binaries in Linux virtual machines.
- Users can identify Intel‑only apps by opening About This Mac, selecting More Info → System Report → Applications, and checking the Kind column.
