TL;DR
Google’s Chrome Platform Status says Chrome 150 will be the final release compatible with macOS 12 Monterey; Chrome 151 and later will not support that OS. Chrome 150 will keep working but won’t receive further updates, including security fixes — users should upgrade to macOS 13 or switch browsers.
What happened
The Chrome Platform Status entry confirms that Chrome 150 will be the last version that runs on Macs using macOS 12 Monterey. Machines left on Monterey will continue to run Chrome 150, but the browser will present a warning infobar indicating it will not receive additional updates. Once Chrome moves to version 151, devices running macOS 12 will fall outside Chrome’s supported platform list and will no longer get bug fixes, performance improvements or security patches from Google. The post links the change to Monterey being outside Apple’s support window. Google has not published a specific cutoff date; the post notes Chrome’s typical four-week major-release cadence and the current stable release number, allowing an approximate projection for when v151 might arrive.
Why it matters
- Without updates, Chrome on macOS 12 will miss security patches and bug fixes, increasing exposure to vulnerabilities.
- Users on Monterey will lose access to new Chrome features and performance improvements that arrive in later releases.
- Staying on an unsupported OS can complicate secure browsing and may force users to upgrade their OS or change browsers.
- Organizations managing fleets of Macs need to track Chrome’s platform support to plan upgrades or mitigations.
