If you're still running macOS Big Sur on your Mac, it's officially time to consider upgrading. Google has announced that Chrome version 138 will be the last version to support Big Sur. After that, users on this operating system will stop receiving updates, including critical security patches, starting with Chrome version 139, expected to launch on August 5, 2025.
Why This Matters
While Chrome will technically still run on Big Sur, you’ll start seeing a prominent warning urging you to update your system. More importantly, the browser won’t get any future updates — which means no new features, no bug fixes, and no security protections. That puts your system at serious risk, especially as cyber threats continue to evolve.
Only Two Browsers Left Standing
With Chrome pulling out, only Mozilla Firefox and Microsoft Edge will continue supporting macOS Big Sur — for now. However, there’s no guarantee how long that will last. Browser developers tend to follow suit once major players like Google stop supporting outdated systems. The clock is ticking.
Chrome’s Departure Hurts
Google Chrome is one of the most widely used web browsers, thanks to its speed, performance, and robust extension library. Losing support means that Big Sur users may have to switch browsers — and that comes with the hassle of migrating bookmarks, saved passwords, extensions, and browsing history.
Even Safari Dropped Big Sur
Apple itself stopped supporting Safari on macOS Big Sur back in July 2023. That’s a strong sign that Big Sur is well past its prime and no longer a priority for updates or compatibility from Apple or third-party developers.

Staying on Big Sur? Think Again.
Older macOS versions are more vulnerable to hacking, malware, and system exploits. While Apple does release occasional security patches for older systems, that support doesn’t last forever. Updating to a newer version like macOS Sequoia not only boosts your security but also unlocks the latest macOS features and performance improvements.
Final Verdict: Don’t Delay — Updating Your Mac Is a Smart Move
If you're still using macOS Big Sur, now is the perfect time to upgrade. Continuing to use an outdated OS limits your options and exposes your Mac to unnecessary risk. With Chrome ending support, and Safari already out, the safest and smartest thing you can do is update your Mac today and keep enjoying a fast, secure, and fully-supported browsing experience.
