You need a browser that gets security updates. If you're still using macOS macOS Big Sur, soon your only choices will be Firefox and Microsoft Edge.

Here's how crucial it is to use a browser that still get updates. Apple recently defended making developers use its WebKit browser engine specifically on the grounds that browsers are such a target for security issues.

So for safety and privacy as much as for any new features, all users should always use the latest version of whichever browser they choose. But now Google that the current Chrome version 138 "will be the last release to support macOS 11."

In a regarding the end of support for Android 8.0 and Android 9.0, Google said that Chrome 139 is tentatively scheduled for release on August 5, 2025.

Google also stresses how it is essential to run supported versions of Chrome. "On Macs running macOS 11, Chrome will continue to work, showing a warning infobar," says the support note, "but will not update any further."

Apple released macOS 11, called Big Sur, in 2020. It was a major redesign that came alongside the transition from Intel processors to Apple Silicon ones.

This is the release when Safari gained built-in translation features, and Apple hoped to see developers port Chrome extensions over to it. Safari dropped support for macOS Big Sur, though, in July 2023 with version 16.6.

Two years later, the current Safari 18.5 requires at least macOS Ventura, which was released in 2022. The developer betas of the forthcoming Safari 26.0 for macOS Tahoe require at least 2023's macOS Sonoma.

So the latest versions of Safari are long out of the picture for macOS Big Sur users, and Chrome is ceasing support from August. This leaves only Firefox and Microsoft Edge whose latest versions still support macOS 11.

On July 16. 2025, the actually supports Macs all the way back to macOS 10.15. That's macOS Catalina, which was released back in 2019.

Microsoft Edge also supports macOS Catalina with its and its previous 127. However, Microsoft Edge version 129 is expected to be released in September, and after that the browser will require macOS Big Sur.
