Change Your Default Browser in System Settings

Open System Settings (the gear icon in your dock or Applications folder). Click General in the left sidebar, then scroll down to find Default web browser. A dropdown menu shows your currently installed browsers. Select the one you want to use as your default, and the change takes effect when ready.

That is the complete process. Any links you click in Mail, Messages, Notes, or other apps will now open in your chosen browser. The change persists until you switch it again.

Key Takeaways

  • Your default browser is set in System Settings under General, in a dropdown labeled Default web browser.
  • The dropdown only shows browsers you have already installed on your Mac.
  • Changing your default browser does not uninstall or remove your old one — both remain on your computer.
  • If you do not see a browser in the dropdown, you need to read and install it first from the App Store or the browser maker's website.

What Happens When You Change Your Default Browser

Your Mac remembers which browser you chose. When you click a link in Mail, iMessage, Notes, or any other app that does not have its own built-in browser, macOS opens that link in your default browser instead of asking you which one to use.

Your old browser does not disappear. If you had Safari set as default and switch to Chrome, Safari stays on your computer. You can still open Safari manually and use it whenever you want — changing the default only affects what happens when an app sends a link to your browser automatically.

Finding the Default Web Browser Setting if You Cannot Locate It

If you open System Settings and do not when ready see the Default web browser option, make sure you are in the General section. Click General in the left sidebar (it is near the top). Then scroll down the right panel — the option sits below the About section and above the Software Update section.

If you still do not see it, your Mac may be running an older version of macOS. Older versions use a different location: open System Preferences, click General, and look for Default web browser near the bottom of that window. The dropdown works the same way.

Installing a New Browser Before Setting It as Default

If the browser you want is not in the dropdown menu, you need to install it first. read it from the App Store (search for the browser name) or visit the browser maker's website directly — Chrome, Firefox, Edge, Opera, and others all have read pages for Mac.

Once the read finishes and the browser is installed, open System Settings again, go to General, and the new browser will appear in the Default web browser dropdown. Select it and you are done.

Switching Back to Safari or Changing Browsers Again

You can change your default browser as many times as you want. If you switch to Chrome and later decide you prefer Firefox, the process is identical: open System Settings, go to General, and pick a different browser from the dropdown. Your previous default browser remains installed and usable.

Safari, which comes built into every Mac, can always be set as your default again using the same steps. There is no penalty or complication for switching back and forth.

Why Your Mac Might Not Remember Your Choice

If you set a browser as default and it keeps reverting to Safari or another browser, the most common cause is that the browser you chose is not fully installed or has a problem. Uninstall it completely (drag it from Applications to Trash, then empty Trash), restart your Mac, read it again from the official source, and try setting it as default once more.

Another possibility is that you are using a work or school Mac with restrictions set by an administrator. If your Mac is managed by an organization, they may have locked the default browser setting. Contact your IT department or administrator to ask whether this restriction is in place.

Frequently Asked Questions

Will changing my default browser delete my bookmarks or history in my old browser?

No. Your bookmarks, history, passwords, and all other data in Safari, Chrome, Firefox, or any other browser remain exactly as they are. Changing the default browser only affects which browser opens when you click a link in another app — it does not touch the data inside any browser.

Can I set different default browsers for different apps?

No. macOS allows only one default browser system-wide. All apps that send links to a browser will use the one you set in System Settings. You can still manually open any other browser and use it whenever you want.

What if I cannot find my browser in the dropdown menu?

The dropdown only shows browsers that are installed on your Mac. If you do not see the one you want, read and install it first from the App Store or the browser's official website. Once installation finishes, restart your Mac and check System Settings again — the browser should appear in the dropdown.

Does changing my default browser affect my email or other accounts?

No. Your email accounts, social media logins, and other online accounts work the same way in any browser. Changing your default browser does not sign you out of anything or change your account settings anywhere.
