Where to find and change your default apps

On a Mac running macOS Monterey or newer, you change default apps in System Settings under the Default Apps panel. Open System Settings (the gear icon in your dock or Applications folder), then click General in the left sidebar. Scroll down and select Default Apps. You'll see a list of app categories—web browser, email, maps, music player, photos, and others—each showing which app is currently set as the default.

Click any category to see all available apps on your Mac that can handle that task. Select the one you want to use going forward. The change takes effect when ready; you don't need to restart your Mac or close any open apps.

If you're running an older version of macOS (Big Sur or earlier), the process differs slightly. You'll find these settings scattered across different preference panes rather than in one central location, and some app categories may not be changeable at all.

Key Takeaways

  • Default apps are changed through System Settings > General > Default Apps on macOS Monterey and newer versions.
  • You can set defaults for web browsers, email clients, maps, music players, photos apps, and a few other categories depending on your macOS version.
  • Changes take effect when ready without restarting your Mac.
  • Older macOS versions (Big Sur and earlier) don't have a unified Default Apps panel, so you'll need to change defaults within each individual app's settings.
  • Some third-party apps may not appear in the default apps list if they don't support the necessary system integration.

What happens when you set a default app

When you set an app as the default for a category, macOS routes all related actions to that app automatically. For example, if you set Firefox as your default web browser, clicking a link in an email, a document, or a text message will open that link in Firefox instead of Safari. The same logic applies to email: setting Outlook as your default email client means clicking an email address will open a new message in Outlook.

This behavior applies to system-wide actions only. If you manually open a different app and use it directly, that app will open links and files normally. Defaults only affect what happens when macOS itself needs to open something on your behalf.

Which app categories can be changed

The number of changeable categories depends on your macOS version. On the newest versions, you can typically set defaults for:

  • Web browser (Safari, Chrome, Firefox, Edge, etc.)
  • Email client (Mail, Outlook, Thunderbird, etc.)
  • Maps app (Apple Maps, Google Maps, etc.)
  • Music player (Apple Music, Spotify, etc.)
  • Photos app (Photos, other image viewers)
  • Calendar app (Calendar, Outlook, etc.)
  • Contacts app (Contacts, Outlook, etc.)

If an app you want to use doesn't appear in the list, it may not support the necessary system integration. Check the app's documentation or settings to see if there's a way to register it as a default handler. Some older or less common apps don't have this capability.

Changing defaults on older macOS versions

If you're running Big Sur or earlier, you won't find a unified Default Apps panel. Instead, you'll change defaults through individual app settings. For your web browser, open System Preferences, click General, and look for the "Default web browser" dropdown at the top. For email, you'll need to open Mail itself, go to Mail > Preferences, and set your default email client there.

Other app categories may not be changeable at all on older versions. If you need to change defaults for maps, music, or photos, check each app's own preferences menu. This scattered approach is one reason Apple consolidated everything into a single panel in newer macOS versions.

Resetting to Apple's default apps

If you want to return to Apple's built-in apps as your defaults, go back to System Settings > General > Default Apps and select Safari for web browsing, Mail for email, Apple Maps for maps, and so on. You can change defaults back and forth as many times as you want with no penalty or side effects.

There's no "reset all to defaults" button, so you'll need to change each category individually if you've customized multiple ones. This takes only a minute or two if you're switching everything back.

Troubleshooting when defaults don't stick

Occasionally a default app change won't take effect, or macOS will revert to a previous default. This usually happens if the app you selected isn't fully installed or if there's a permissions issue. Try closing the app completely, then reopening System Settings and selecting it again. If that doesn't work, restart your Mac and repeat the process.

If a third-party app keeps reverting to Safari or Mail, the app itself may not be properly registered with macOS. Check the app's settings or support documentation to see if there's a step you missed during installation. Some apps require you to grant permission or run a setup wizard before they can be set as defaults.

Why your default app might not open

Setting a default app doesn't may provide it will open every time. If you click a link and nothing happens, the app may not be running, or it may have crashed. Try opening the app manually first, then clicking the link again. If the wrong app opens instead of your default, check System Settings again to confirm your choice was saved.

Another common issue: some older websites or documents may have hardcoded links that bypass your defaults and open in a specific app. This is rare but can happen with legacy web content or PDFs that were created with specific software in mind.

Frequently Asked Questions

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

Yes. Each user account on your Mac has its own System Settings, so you can set different defaults for each person. Log in as a different user and change the defaults through their System Settings. The changes explore only to that account.

What if an app I want to use doesn't show up in the Default Apps list?

The app may not support being set as a default, or it may not be fully installed. Try reinstalling the app from the App Store or the developer's website. If it still doesn't appear, check the app's documentation to see if it supports this feature. Older or niche apps sometimes don't have this capability.

Do I need to restart my Mac after changing a default app?

No. Changes take effect when ready. You can start using your new default app right away without closing anything or restarting your computer.

Can I set defaults for apps that aren't from Apple?

Yes. Any app that supports being set as a default will appear in the Default Apps list, whether it's from Apple, Microsoft, Google, or another developer. If you've installed a third-party browser, email client, or maps app, you should be able to set it as your default.

What happens to files I created with my old default app?

Changing your default app doesn't affect files you've already created. A document you made in Safari will still open in Safari by default, even if you've set Chrome as your default browser. Defaults only affect new actions going forward.
