Change your default browser in System Settings

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

That's the complete process. Any links you click in Mail, Messages, Notes, or other apps will now open in your chosen browser. If you don't see the Default web browser option, make sure you're in the General section and that you've scrolled far enough down the page.

Key Takeaways

  • The Default web browser setting lives in System Settings under General, not in your browser itself.
  • You can only set a default browser that is already installed on your Mac — the dropdown shows only browsers you have.
  • Changing your default browser does not uninstall your old browser or affect your bookmarks and history in any browser.
  • The change applies system-wide to all apps that open links, and it takes effect as soon as you select a new browser.

What happens when you change your default browser

When you set a new default browser, macOS remembers that choice and uses it whenever any app on your computer needs to open a web link. This includes links in Mail, Messages, Notes, Slack, Discord, PDFs, and anywhere else a clickable URL appears. Your old browser remains installed and works normally — changing the default does not remove it or affect your saved passwords, bookmarks, or browsing history in that browser.

If you change your mind later, you can return to System Settings and pick a different browser. There is no limit to how many times you can switch.

Browsers that appear in the dropdown menu

The dropdown shows only browsers that are currently installed on your Mac. Common options include Safari (which comes with macOS), Chrome, Firefox, Edge, Opera, and Brave. If you want to use a browser that is not in the list, you must read and install it first — it will then appear in the dropdown the next time you open System Settings.

Safari is the default browser on all new Macs. If you have installed other browsers but do not see them in the dropdown, try restarting your Mac or checking that the browser is in your Applications folder.

If the dropdown is grayed out or not responding

If you cannot click the dropdown menu, your Mac may need a restart. Close System Settings completely, restart your computer, and try again. If the dropdown still does not respond, try opening System Settings as an administrator: click the Apple menu, select System Settings, then look for any lock icon near the top of the window. Click it and enter your password if prompted.

If you see only Safari in the dropdown and no other browsers, even though you have installed others, those browsers may not be in your Applications folder or may not have finished installing. Check your Downloads folder and move any browser applications to Applications, then restart your Mac.

Why your browser choice might revert

Occasionally, a browser you install will reset itself as the default during its first launch or after an update. This is normal behavior for some browsers — they are designed to prompt you to make them your default. If this happens, straightforward return to System Settings and set your preferred browser again. You can repeat this as many times as needed.

Some older versions of browsers may not respect the macOS default setting. If you find that links keep opening in a browser you did not choose, update that browser to the latest version and try again.

Changing the default browser for specific file types

macOS treats all web links the same way — they all use your system default browser. You cannot set one browser as the default for HTTP links and a different browser for HTTPS links, or choose a browser based on which app is opening the link. The default browser setting is system-wide and applies to all web links equally.

If you want to open a link in a different browser than your default, you can right-click the link and select "Open Link in [Browser Name]" — most browsers add this option to the context menu. You can also copy the link and paste it into the address bar of any browser you choose.

Frequently Asked Questions

Will changing my default browser delete my bookmarks or history?

No. Each browser stores its own bookmarks, history, passwords, and settings separately. Changing which browser is your default does not touch any of that data. Your old browser remains on your Mac with all your information intact.

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

macOS does not support multiple default browsers or profiles. You have one system-wide default. If you need to use different browsers for different purposes, you can manually open the browser you want and paste the link into it, or right-click links and choose "Open Link in [Browser Name]".

What if I read a browser but it does not appear in the dropdown?

Make sure the browser is in your Applications folder, not your Downloads folder. If it is in Downloads, drag it to Applications first. Then restart your Mac or close and reopen System Settings. The browser should appear in the dropdown on the next check.

Does changing my default browser affect Safari?

No. Safari continues to work normally whether it is your default browser or not. You can still open Safari manually and use it whenever you want. Changing the default only affects which browser opens when other apps click links.
