Google Chrome 139 Drops macOS 11 Support: What It Means for Big Sur Users
Google Chrome 139, launching July 30, 2025, will end support for macOS 11 Big Sur. Learn what this means for Mac users, security, and upgrading options.
The End of an Era for Big Sur: Chrome 139 Moves On
For thousands of Mac users, the digital landscape is about to shift. Google confirmed that Chrome 139, rolling out July 30, 2025, will not run on macOS 11 Big Sur. If you’re still using Big Sur, Chrome 138 is officially the last version you’ll be able to update. After that, everything from security patches to the coolest web features will be beyond your reach—unless you upgrade your OS.
Why Google is Saying Goodbye to macOS 11
Let’s be honest: tech companies don’t drop support for operating systems on a whim. Apple itself put Big Sur to pasture in November 2023, so Google’s continued support was actually a kindness that lasted longer than many expected. Think of it as that friend who stays late to help clean up after everyone else has left the party. But parties end, and so must support.
“This decision frees up resources to focus on newer platforms, while nudging users towards better security and performance,” said a Chrome product engineer in the community discussion boards. In other words, those hours spent squashing bugs for an OS few folks use are better spent improving things for newer Macs.
What Happens If You Stay on Big Sur?
Don’t panic—your old version of Chrome won’t suddenly stop working. If you stick with macOS 11, Chrome 138 will keep browsing just fine, but you’ll see a warning and you’ll be out of the update loop. Here’s what that means:
- No Security Fixes: Your browser won’t get patched for new vulnerabilities. That spells real risk—hackers love an unguarded browser.
- No New Features:Â Fancy new Chrome tools, design changes, and web compatibility? Off-limits if you stay behind.
- Gradual Performance Hit: Over time, older browsers slow down and break on websites that assume you’ve updated.
Who Will Still Be Supported?
Google Chrome 139 sets its baseline at macOS 12 Monterey. If you’re running Monterey, Ventura, Sonoma, or the hot-off-the-presses macOS 15 Sequoia, everything’s business as usual. For those on Big Sur, the message is clear: it’s upgrade-or-bust.
| Chrome Version | Last Supported macOS | Release Date | Support Status |
|---|---|---|---|
| 138 | macOS 11 Big Sur | June/July 2025 | Last Version for Big Sur |
| 139+ | macOS 12+ Monterey | July 30, 2025 | Full Support |
What About Other Devices?
It’s not just Macs feeling that nudge from Google. Chrome 139 will also require Android 10 or higher, leaving Android 8.0 (Oreo) and 9.0 (Pie) users in the same update void. It’s a mass migration, driven by the promise of better security and more unified development.
The Broader Picture: Software Lifecycles and User Security
Letting go of older software isn’t just about new features or keeping up with the Joneses—it’s about cybersecurity. Vendors like Google and Apple routinely phase out legacy platforms to funnel resources into what most people are actually using and to reinforce defenses against modern threats.
When companies make these moves, they often look at usage stats, the real cost of backporting fixes, and whether the platform owner (here, Apple) is still issuing security updates. With Big Sur now a ghost in Apple’s official support lineup, Chrome hopping off at the same stop only makes sense.
Real-Life Ripples: What Should Mac Users Do?
Let’s cut to real talk. If you squirm at the thought of OS upgrades—hey, you wouldn’t be alone. Maybe there’s old creative software you love, or you just dread the process. But the risks quickly start to outweigh the hassle.
If you’re clinging to Big Sur and Chrome is central to your work or daily browsing, here’s your best bet:
- Plan That macOS Upgrade:Â Even if Sonoma or Sequoia feels intimidating, these newer macOS releases offer better security and compatibility. Apple has detailed guides to smooth the process.
- Consider Alternative Browsers: Some, like Firefox, might hang onto older Mac support for a little longer—but there’s no guarantee or timeline.
- Emphasize Security: Don’t ignore warning banners. Unsupported browsers and OSes are magnets for malware and phishing attacks.
Final Thoughts
Change is relentless in the tech world. Google’s decision to end Chrome support for macOS 11 Big Sur with version 139 isn’t personal—it’s just progress. For folks still running Big Sur, consider this your sign: embrace an upgrade, protect your online life, and keep cruising the web with the tools and defenses you deserve. You’re not alone in the journey—millions are upgrading right beside you.
