Older Mac computers will lose Google Chrome support

Google plans to end Chrome support for macOS 12 Monterey when Chrome 151 ships, making Chrome 150 the last release that will run on macOS 12; Chrome 151 is expected around mid-2026 and will require macOS 13 (Ventura) or newer.

Google has announced a change to Chrome's minimum macOS requirement that affects older Mac computers. The company is preparing Chrome 151 to require macOS 13 (Ventura) or newer. As a result, macOS 12 Monterey will no longer be a supported platform for new Chrome releases. Key facts: - Chrome 150 is reported to be the final Chrome release compatible with macOS 12 Monterey. - Chrome 151 will require macOS 13 (Ventura) or later, and installers for that release will check the operating system. - Google said the move is tied to security and the need to run Chrome on an operating system that remains supported by its vendor. - The current Chrome version is around 143 and Google typically issues major updates about every four weeks, which points to Chrome 151 arriving around mid-2026. - If Chrome stops supporting macOS 12, the browser will continue to run but will no longer receive security patches or feature updates and will display an outdated warning infobar. - The article reports that Firefox currently still supports macOS Monterey as an available browser that continues to receive updates for that OS. Summary: The change will mean that Macs still running macOS 12 will stop receiving new Chrome security fixes and features once Chrome 151 is released, and users will see a persistent outdated warning in the browser. Chrome 151 is expected around mid-2026 and will set macOS 13 as the minimum supported macOS. Undetermined at this time.
