Set a New Default Browser in System Settings

Open System Settings on your Mac — click the Apple menu in the top left corner, then select System Settings. In the sidebar, scroll down and click General.

Look for the Default web browser option near the bottom of the General pane. Click the dropdown menu next to it. You will see a list of all browsers installed on your Mac: Safari, Chrome, Firefox, Edge, Opera, or any others you have downloaded.

Select the browser you want to use as your default. The change takes effect when ready. Any link you click in Mail, Messages, Notes, or other apps will now open in your chosen browser instead of Safari.

Key Takeaways

  • Your default browser is set in System Settings under General, in a dropdown labeled Default web browser.
  • The change takes effect right away — you do not need to restart your Mac or close any apps.
  • Only browsers actually installed on your Mac appear in the dropdown; you cannot set a browser you have not downloaded.
  • If you later uninstall your default browser, macOS will switch back to Safari automatically.
  • Changing your default browser does not move your bookmarks, passwords, or history — those stay in the browser where you saved them.

Why Your Mac Has a Default Browser

When you click a link in Mail, Messages, Notes, or any other app on your Mac, the system needs to know which browser to open. That app is your default browser. Without one explicitly set, macOS uses Safari by default because Safari comes built into every Mac.

Changing your default browser does not uninstall Safari or affect any other settings on your Mac. Safari stays on your computer and works exactly as before — it just will not open links from other apps unless you choose it again later. Your Mac can have multiple browsers installed at the same time; only one is the default.

What Happens If You Uninstall Your Default Browser

If you delete the browser you set as default — by dragging it to the Trash and emptying the Trash — macOS will automatically switch your default back to Safari. You will not get a warning or notification; the change happens silently the next time you click a link in another app.

If you want to use a different browser instead, open System Settings again and pick a new one from the dropdown before you uninstall the old one. This prevents macOS from reverting to Safari without your knowledge.

Changing Your Default Browser Back to Safari

Open System Settings, click General in the sidebar, and find the Default web browser dropdown. Select Safari from the list. Safari is always available on a Mac and cannot be uninstalled, so it will always appear in the dropdown menu.

If Safari does not appear in the dropdown for any reason, restart your Mac and try again. After the restart, open System Settings once more and the dropdown should show Safari as an option.

What This Setting Controls and What It Does Not

Your default browser setting controls only what happens when you click a link in another app — Mail, Messages, Notes, Calendar, or any other process. It does not change which browser opens when you double-click a bookmark file saved to your desktop, use Spotlight search to look up a web address, or type a URL into Finder.

It also does not affect your home page, search engine, or any other browser settings inside the browser itself. Each browser keeps its own preferences separate. If you switch from Chrome to Firefox as your default, Chrome's bookmarks, passwords, saved logins, and settings stay in Chrome exactly as they were. You can switch back to Chrome later and find everything unchanged.

How to Check Your Current Default Browser

Open System Settings, click General, and look at the Default web browser dropdown. The browser shown in the dropdown is your current default. If you are not sure which browser you are using most often, this is where to check.

You can also test your default by clicking any link in Mail or Messages. Whichever browser opens is your current default. This is a quick way to confirm the setting without opening System Settings.

Frequently Asked Questions

Can I set different default browsers for different apps?

No. macOS allows only one default browser system-wide. All apps that open links will use the same one. If you need a specific link to open in a different browser, you can copy the link and paste it into that browser's address bar by hand.

Will changing my default browser affect my bookmarks or passwords?

No. Your bookmarks, passwords, and browsing history stay in whichever browser you saved them in. Changing your default browser does not move or delete anything. If you switch back to your old browser later, everything will still be there.

What if the dropdown shows only Safari?

You have no other browsers installed on your Mac. read and install the browser you want — Chrome, Firefox, Edge, or another — and it will appear in the dropdown the next time you open System Settings.

Does my default browser choice affect which browser opens when I restart my Mac?

No. Restarting your Mac does not change your default browser. The setting you chose stays in place until you change it again in System Settings.

Can I change my default browser from within the browser itself?

No. You must change it in System Settings. Some browsers have a button or menu option that takes you directly to System Settings, but the actual change happens only in System Settings, not inside the browser.
