Change your default browser in System Settings

Your default browser is the app that opens when you click a link in an email, document, or web page. On Mac, you change this in System Settings, not in the browser itself. The process takes about one minute and works the same way whether you want to switch to Chrome, Firefox, Safari, Edge, or any other browser.

Open System Settings by clicking the Apple menu in the top-left corner of your screen, then select System Settings. On older Macs running Monterey or earlier, this app is called System Preferences instead. The steps are identical either way.

Once System Settings is open, look for the section called Default apps or General (depending on your macOS version). Click it, then scroll down until you see Default web browser. Click the dropdown menu next to it — it currently shows your existing default browser — and select the browser you want to use instead.

Key Takeaways

  • Your default browser is set in System Settings under Default apps or General, not within the browser program itself.
  • The change takes effect immediately and applies to all links you click outside of web browsers.
  • You can change your default browser back to Safari or any other installed browser at any time using the same steps.
  • If your preferred browser does not appear in the dropdown menu, the app may not be installed or may need to be restarted.

What happens after you change your default browser

Once you select a new default browser and close System Settings, the change is active right away. The next time you click a link in Mail, Messages, a PDF, or any other app, your new browser will open instead of the old one.

This does not affect browsers you already have open. If Safari is running and you switch your default to Chrome, Safari stays open — Chrome just becomes the app that handles new link clicks going forward. You can have multiple browsers installed and running at the same time; only one is the default.

If your browser does not appear in the dropdown menu

Sometimes the browser you want to set as default does not show up in the list. This usually means one of two things: the app is not installed on your Mac, or the app needs to be restarted after installation.

If you just installed a new browser, quit it completely and then open it again. This lets macOS recognize it as an option for the default browser dropdown. Close System Settings too, then reopen it and check the Default web browser menu again. The newly installed browser should now appear in the list.

If the browser still does not show up, make sure it is actually installed in your Applications folder. Open Finder, click Applications in the sidebar, and look for the browser by name. If it is not there, download and install it from the browser's official website first.

Switching back to Safari or changing browsers again

You can change your default browser as many times as you want. The process is always the same: open System Settings, go to Default apps, click the Default web browser dropdown, and pick a different browser from the list.

If you want to go back to Safari (which is the default on all new Macs), follow the same steps and select Safari from the dropdown. There is no penalty for switching back and forth, and your bookmarks, passwords, and browsing history in each browser stay exactly where they are.

Why your default browser matters

Your default browser handles links you click outside of web browsers. If you receive a link in an email and click it, your default browser opens. If you click a link in a Word document, a PDF, or a Slack message, your default browser opens. This is why many people set their most-used browser as the default — it saves time by opening the browser they already have bookmarks and passwords saved in.

Setting a default does not prevent you from using other browsers. You can still open Chrome, Firefox, Safari, or any other browser manually whenever you want. The default only controls what happens when something outside a browser tries to open a web page.

Troubleshooting: Your default browser keeps changing

Occasionally, after you set a new default browser, it switches back to Safari or another browser on its own. This usually happens after a macOS update or after you restart your Mac. If this occurs, go back to System Settings, check the Default web browser dropdown, and set your preferred browser again.

If the default keeps reverting even after you set it multiple times, try quitting the browser completely, waiting a few seconds, and then opening it again before changing the default. Sometimes a browser that is not fully loaded cannot register itself as a valid default option, which can cause the system to revert to Safari.

Frequently Asked Questions

Does changing my default browser affect my bookmarks or passwords?

No. Your bookmarks, passwords, and browsing history stay in each browser where you saved them. Changing your default browser only changes which app opens when you click a link outside of a browser. Your data in Chrome, Firefox, Safari, or any other browser remains untouched.

Can I set different default browsers for different types of links?

No. macOS allows only one default browser for all links. You cannot set Chrome as the default for work links and Firefox for personal links. You can only choose one browser to handle all link clicks from outside applications.

What if I uninstall my default browser?

If you uninstall your default browser, macOS automatically switches the default back to Safari. The next time you click a link, Safari will open. You can then set a different browser as the default if you want.

Do I need to restart my Mac after changing the default browser?

No. The change takes effect immediately. You do not need to restart your Mac or close and reopen System Settings. The next link you click will open in your new default browser.

Why does Safari keep becoming my default browser?

Safari is the system default on all Macs. Some macOS updates reset your default browser back to Safari. If this happens, return to System Settings, open the Default web browser dropdown, and select your preferred browser again. You may need to do this after major macOS updates.
