Overview
- macOS 27 Golden Gate entered developer beta in June 2026 and is the final macOS to ship with full Rosetta 2, which Apple says will be removed as a general-purpose translator in the next major release.
- Golden Gate runs only on Apple silicon and adds a new System Settings Intel‑based Apps panel that lists apps opened in the past year and warns that Intel apps will not open in macOS 28.
- The update will automatically uninstall Rosetta 2 for users upgrading from macOS 26 Tahoe, requiring anyone who still needs Intel translation to reinstall Rosetta or remain on macOS 27.
- Most mainstream apps have been rebuilt for Apple silicon since 2020, but specialized, legacy, and some enterprise Intel‑only software will need native updates or replacement to keep working.
- Apple began the transition in 2020 and shipped its last Intel Mac in 2023; the company will keep a narrow Rosetta subset for older, unmaintained games and plans a public beta next month with a full release expected in September 2026.
