Overview
- Chrome 138 will be the last release to run on macOS Big Sur, displaying a warning infobar and no longer receiving feature or security updates.
- Chrome 139, scheduled to ship on July 30, will require macOS Monterey (12) or later for new installations, excluding Big Sur entirely.
- Big Sur users face growing security risks after Apple ended system updates earlier this year and Google follows suit by freezing Chrome on macOS 11.
- Affected users must upgrade their operating system, switch to alternative browsers still supporting Big Sur, or acquire newer hardware to stay protected.
- Advanced users may employ community tools like OpenCore Legacy Patcher to run newer macOS versions on unsupported machines, though the process is complex and unofficial.
