You probably think your browser is fine. It’s sitting there, open with forty tabs, humming along while you ignore 그 little red or yellow "Update" bubble in the corner. Honestly, most of us treat browser updates like a dental appointment—something to be pushed off until there’s a real problem. But here’s the thing about learning how to update Google Chrome on Mac: it’s not just about getting new features or a slightly cleaner UI. It’s about not letting your MacBook become a playground for zero-day exploits.
Chrome is a memory hog. We all know it. But it's also the most targeted piece of software on your machine because it's your window to the entire internet. When Google pushes an update, they aren't just messing with your extension layout. They’re usually patching a hole that someone discovered five minutes ago.
The Fast Way to Get It Done
Let’s get the basic mechanics out of the way first. You don't need to go to the website and redownload the .dmg file. That’s a waste of time. Instead, just look at the top right corner of your browser window. If you see a button that says "Update," click it. Chrome color-codes these alerts. Green means an update has been waiting for two days. Orange means four days. Red? You’ve been ignoring it for a week, and you’re basically inviting trouble.
If the button isn't there, click the three vertical dots (the "Kebab" menu). Go down to Help and then select About Google Chrome.
This is the magic screen. The moment you land here, Chrome starts reaching out to Google’s servers. It checks your current version—something like Version 120.0.6099.129—and compares it to the latest build. If you're behind, it starts downloading automatically. You’ll see a percentage bar. Once it hits 100, a "Relaunch" button pops up. Click it. Chrome shuts down, saves your tabs (mostly), and pops back up in seconds.
Why Your Mac Might Be Blocking the Update
Sometimes, things break. You click "About Google Chrome," and instead of a smooth download, you get an error code. Error 11 or Error 12 are the usual suspects on macOS. This often happens because of "permissions." macOS is incredibly protective of its Applications folder. If you didn't install Chrome as an administrator, or if your user profile doesn't have the right "Write" access, the update will fail every single time.
It’s annoying.
To fix this, you might need to check your "Keystone" settings. Keystone is the background service Google uses to keep things current. If you’ve used a "Mac cleaner" app or a script to "de-bloat" your system, you might have accidentally killed the very service that handles the update. In those cases, the easiest fix is actually the "nuclear" option: drag Chrome to the Trash, go to the official Google Chrome download page, and grab a fresh copy. You won’t lose your bookmarks as long as you're signed into your Google account.
The "Automatic" Myth
Google says Chrome updates automatically. That’s a bit of a half-truth. While Chrome downloads the files in the background, it won't actually apply the update until you restart the browser. If you’re the type of person who never closes their laptop and just lets it sleep for three weeks at a time, you are running an outdated, vulnerable version of Chrome.
You have to quit the app. Command + Q is your friend here.
Checking for Apple Silicon vs. Intel Versions
If you bought a Mac in the last few years, you likely have an M1, M2, or M3 chip. This is "Apple Silicon." Older Macs run on Intel processors. There are two distinct versions of Chrome for these different architectures. If you used Migration Assistant to move from an old Mac to a new one, you might accidentally be running the Intel version of Chrome on an M3 Max MacBook Pro.
It’ll work, thanks to a layer called Rosetta 2, but it’ll be slow. And it might be buggy when it tries to update.
To check this, click the Apple icon in your menu bar, hit About This Mac, and see what it says under "Processor" or "Chip." Then, in Chrome, go back to that "About" page. If you see "Mac (ARM64)," you're on the right version for Apple Silicon. If it just says "Mac," you might be running the Intel version and should probably reinstall the correct one to get a massive speed boost.
Security is the Real Reason to Care
Let’s talk about the "why." In 2023 and 2024, Google had to patch several "Zero-Day" vulnerabilities in the V8 JavaScript engine. These aren't theoretical. These are bugs that hackers were actively using to break into computers. When you figure out how to update Google Chrome on Mac and actually follow through, you’re closing the door on those specific attacks.
Security researchers like those at Mandiant or Google's own Project Zero spend thousands of hours finding these flaws. When a patch is released, the "bad guys" also see it. They reverse-engineer the patch to see what it fixed, which effectively gives them a map of how to attack people who haven't updated yet.
Waiting is literally giving them a head start.
Extensions Can Be a Problem Too
Sometimes a Chrome update breaks an extension you love. Maybe it's a dark mode toggle or a specific ad blocker. This leads some people to intentionally stay on old versions. Don't do that. It’s better to find a new extension than to run a browser with known security holes. Most reputable developers update their extensions within 24 hours of a major Chrome release anyway.
If an extension stops working after an update, go to chrome://extensions, toggle on "Developer mode" in the top right, and click "Update." This forces all your add-ons to grab their latest versions.

The Chrome Settings You Should Check Right Now
While you're poking around the update menu, do yourself a favor. Go to Settings, then Privacy and Security, and run the Safety Check. It takes five seconds. It’ll tell you if your passwords have been leaked, if "Safe Browsing" is turned on, and—crucially—if your version of Chrome is up to date.
It’s a quick health check that most people ignore.
What to Do If Chrome Won't Open After an Update
It happens. You update, you relaunch, and then... nothing. A bouncing icon in the Dock that eventually just stops. Or a "Chrome quit unexpectedly" error.
This is usually a corrupted "Profile" issue. Your profile stores your history, cookies, and settings. Sometimes the update process trips over a weird file in your library. To fix this without losing everything, you can try renaming your "Default" folder.
- Open Finder.
- Press Command + Shift + G.
- Paste this:
~/Library/Application Support/Google/Chrome/ - Find the folder named "Default" and rename it to "Backup Default."
- Try opening Chrome again.
If it opens, the update was fine, but your local data was the problem. You can then try to sync your data back from your Google account.
Actionable Next Steps for a Faster, Safer Mac
Don't just read this and go back to your tabs.
First, look at that top right corner. If there's a colored bubble, click it and hit Relaunch. If not, go to Help > About Google Chrome right now to force a manual check.
Second, make it a habit to actually quit Chrome at the end of the day. Command + Q. It’s simple, but it ensures that background downloads actually get installed.
Lastly, if you're on a newer Mac, verify you’re running the "ARM64" version. It’s the difference between a browser that feels "fine" and one that feels lightning fast. Updating isn't a chore; it’s the easiest maintenance you can do to keep your Mac running the way it was meant to.
Check your version, click the button, and get back to work. Your Mac will thank you for it.
