Set a new 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. A dropdown menu will show your currently installed browsers. Select the one you want to use as your default, and the change takes effect immediately.

That's the complete process. Any link you click in Mail, Messages, Notes, or other apps will now open in your chosen browser instead of the one that was set before. You don't need to restart your Mac or the browser itself.

If the browser you want doesn't appear in the dropdown, it may not be installed yet. Download it from the App Store or the browser maker's website, then return to System Settings and select it.

Key Takeaways

  • Your default browser is changed through System Settings > General > Default web browser, not through the browser itself.
  • The change applies immediately to all apps on your Mac that open web links.
  • Only browsers you have already installed will appear in the dropdown menu.
  • You can change your default browser as many times as you want; there is no limit or penalty.

Why your default browser matters

Your default browser is the one that opens whenever you click a link outside of a web browser—in an email, a text message, a document, or a notification. If you don't set one, macOS uses Safari by default. Changing it means you can use Chrome, Firefox, Edge, Opera, or another browser for all those moments without having to copy the link and paste it manually.

Some people keep Safari as their default because it integrates with other Apple apps and uses less battery. Others prefer Chrome because they sync bookmarks and passwords across devices, or Firefox for privacy features. The choice is yours, and you can switch whenever your needs change.

What to do if the browser doesn't stay as default

Occasionally, after you update macOS or install a new version of a browser, Safari resets itself as the default. This is not a bug you caused—it's how macOS handles major updates. Simply return to System Settings > General > Default web browser and select your preferred browser again.

If a browser keeps reverting to Safari even without updates, check whether you have any browser extensions or third-party tools that might be changing this setting. Uninstall anything you don't recognize, then set your default browser again.

Changing the default browser for specific tasks

You don't have to use the same browser for everything. If you want Safari to open links from Mail but Chrome to open links from your web browser, that's not possible—the default applies system-wide. However, you can manually choose which browser opens a link by right-clicking it and selecting "Open with" from the menu, then choosing the browser you want.

This workaround is useful if you need a specific browser for one task but prefer a different one most of the time. It takes a few extra seconds, but it gives you full control over which browser handles each link.

Browsers available on Mac and where to find them

Safari comes built into every Mac and cannot be removed. Chrome, Firefox, Edge, Opera, and Brave can all be downloaded for free from the App Store or directly from each company's website. Downloading from the App Store is simpler because the browser updates automatically. Downloading directly from the maker's website gives you the latest version immediately but requires you to check for updates yourself.

Once installed, any of these browsers can be set as your default. There is no cost, no account required, and no restriction on how many you can install at once. You might keep Safari for everyday use and Chrome for work, for example, then switch the default depending on what you're doing.

Checking which browser is currently your default

To see which browser is set as your default right now, open System Settings, click General, and scroll to Default web browser. The name shown in the dropdown is your current default. If you're not sure which one you want to use, try each one for a few days and switch back if you prefer the other.

You can also test your default by clicking a link in Mail or Messages and watching which browser opens. If it's not the one you expected, return to System Settings and change it.

Frequently Asked Questions

Can I set different default browsers for different user accounts on the same Mac?

Yes. Each user account on your Mac has its own System Settings. Log in as a different user, open System Settings > General > Default web browser, and choose a different browser. Each account will remember its own preference.

Does 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 only changes which one opens links from other apps. If you want to use bookmarks from Chrome in Firefox, you'll need to export them from Chrome and import them into Firefox separately.

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

Open System Settings > General > Default web browser and select Safari from the dropdown. Safari is always available as an option, even if you haven't used it in months.

Will changing my default browser slow down my Mac?

No. Your default browser setting only controls which app opens when you click a link. It doesn't affect how many apps run in the background or how much memory your Mac uses. If you want to reduce slowness, close browsers you're not actively using.
