Change your default browser in System Settings

Open System Settings on your Mac. Click General in the sidebar, then scroll down and look for Default web browser. Click the dropdown menu — it currently shows your active default browser — and select the browser you want to use instead. That's it. The change takes effect immediately.

The dropdown shows every browser installed on your Mac. If the browser you want isn't listed, you need to install it first. Download it from the publisher's website or the App Store, then return to System Settings and select it from the dropdown.

This setting controls which browser opens when you click a link in email, Messages, Calendar, or any other app. It also determines which browser launches when you type a web address into Spotlight search. Changing it here doesn't uninstall your old browser — it just stops using it as the default.

Key Takeaways

  • Go to System Settings, click General, scroll to Default web browser, and choose from the dropdown menu.
  • The change takes effect immediately and applies to all links opened from other apps.
  • Your old browser remains installed; changing the default only stops it from opening automatically.
  • If your preferred browser doesn't appear in the dropdown, install it first from the publisher's website or App Store.

What happens to your old browser

Changing your default browser does not remove or disable the browser you were using before. Safari, Chrome, Firefox, Edge, or any other browser you had installed stays on your Mac and works exactly as it did. You can still open it manually and use it whenever you want.

The only thing that changes is automatic behavior. Links that used to open in your old browser now open in the new one. If you want to use your old browser for a specific link, you can still open it manually and paste the address in, or right-click the link and choose to open it in a different browser.

Why your Mac asks you to set a default

macOS needs to know which browser to use when you click a link outside of a browser window. Without a default set, your Mac wouldn't know whether to open Safari, Chrome, Firefox, or something else. Setting a default prevents that confusion and makes links work smoothly from email, messages, and other apps.

If you've never set a default browser, macOS uses Safari by default. This is Apple's own browser and comes pre-installed on every Mac. Changing it is optional — you only need to do it if you prefer a different browser.

Changing the default browser from within the browser itself

Some browsers offer a shortcut to set themselves as default. Open the browser you want to use, then look in its settings or preferences menu. Chrome, Firefox, and Edge all have an option that says something like "Make [Browser Name] the default browser" or "Set as default." Clicking this button takes you directly to System Settings with the right browser already selected in the dropdown.

This method is faster if you're already in the browser you want to switch to, but it does the same thing as changing it manually in System Settings. Either way works.

Switching between browsers for specific tasks

You don't have to use the same browser for everything. Even with one browser set as default, you can open a different browser manually whenever you want. Many people keep multiple browsers installed and use them for different purposes — one for work, one for personal browsing, one for testing websites.

If you want a link to open in a non-default browser, right-click the link and look for an option like "Open Link in [Browser Name]." Not all websites and apps support this, but most do. You can also copy the link address and paste it into whichever browser you choose to use.

Troubleshooting: Your default browser won't change

If you change the default browser in System Settings but links still open in the old one, restart your Mac. Sometimes the change doesn't take effect until you restart. Close all open apps, restart, and try clicking a link again.

If restarting doesn't work, check that you actually selected a different browser in the dropdown. Open System Settings again, go to General, and confirm the browser you want is showing in the Default web browser field. If it's not there, the browser may not be fully installed — try installing it again from the App Store or the publisher's website.

Frequently Asked Questions

Can I set a different default browser for work and personal use?

No. macOS allows only one default browser at a time. You can switch between them manually by opening different browsers or right-clicking links to choose which one to use, but you can't have two defaults running simultaneously.

Will changing my default browser affect my bookmarks or saved passwords?

No. Each browser stores its own bookmarks and passwords separately. Changing which one is default doesn't touch any of that data. Your old browser keeps everything it had, and your new default browser has its own separate collection.

What if I want to go back to Safari as my default?

Open System Settings, click General, find Default web browser, and select Safari from the dropdown. Safari is always available in the list since it comes built into macOS. The change takes effect immediately.

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

Usually not. The change takes effect right away in most cases. If links still open in your old browser after changing the setting, try restarting your Mac — sometimes the system needs a restart to apply the change fully.
