Change your 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 Desktop & Dock.
Scroll down in the main panel until you see Default web browser. Click the dropdown menu next to it, which currently shows your existing default (usually Safari). A list of installed browsers appears — select the one you want to use instead. The change takes effect immediately.
That is the only step. Any link you click in Mail, Messages, Notes, or other apps will now open in your chosen browser. Bookmarks you save from other apps will also go to the new default.
Key Takeaways
- Your default browser is set in System Settings under Desktop & Dock, not in the browser itself.
- Only browsers actually installed on your Mac appear in the dropdown — you cannot set a browser you have not downloaded.
- Changing the default affects links in Mail, Messages, Notes, and other system apps, but not links opened within a different browser.
- You can change your default browser as many times as you want; there is no limit or penalty.
- Each browser keeps its own bookmarks, passwords, and history — changing the default does not move data between them.
What happens when you change your default
When you set a new default browser, macOS stops routing links to your old one. If you click a link in Mail, it opens in your new default. If you click a link on a web page you are already viewing in a different browser, that link stays in the browser you are using — the default only matters for links outside a browser window.
Your bookmarks, passwords, and browsing history stay in each browser where you created them. Changing the default does not move or copy data between browsers. If you switch from Safari to Chrome, your Safari bookmarks remain in Safari unless you manually export and import them. The same applies to passwords saved in each browser — they do not transfer automatically.
If you later switch back to your original browser, all your data will still be there exactly as you left it. Changing defaults is reversible and does not affect the browser's internal storage.
If your browser does not appear in the dropdown
A browser only shows up in the default browser list after you have downloaded and opened it at least once. If you recently installed a browser but do not see it in the dropdown, open the browser first — launch it from Applications or Spotlight, let it fully load, then close it. Go back to System Settings and check the dropdown again.
If the browser still does not appear, the installation may have failed. Try downloading it again from the official website. For Chrome, visit google.com/chrome. For Firefox, go to mozilla.org/firefox. For Edge, visit microsoft.com/edge. Drag the downloaded app to your Applications folder, open it once, then return to System Settings.
Some older browser versions may not support the default browser setting on newer versions of macOS. If you are running an older browser, check the developer's website to see if an update is available.
Switching back to Safari
If you want to return Safari as your default, follow the same steps: open System Settings, go to Desktop & Dock, find Default web browser, and select Safari from the dropdown. Safari is the default on a new Mac, so you are simply resetting to the original choice.
Switching away from Safari and back does not affect Safari itself — your bookmarks, history, and saved passwords remain unchanged. You can switch defaults as often as you need without losing anything.
Why your choice matters for links outside browsers
The default browser setting only controls what happens when you click a link outside a web browser. If you are reading an email in Mail and click a link, macOS uses your default browser. If you are in a document, a text message, a Slack conversation, or any other app and click a link, the default browser opens it.
Within a browser itself, links always stay in that browser. If you are viewing a webpage in Firefox and click a link on the page, it opens in Firefox — not your default browser. The default only applies to links that originate outside a browser window. This distinction matters if you use multiple browsers for different purposes.
Opening links in a different browser when you need to
If your default browser is set to Chrome but you want to open a specific link in Firefox instead, right-click the link and look for an option like "Open Link in Firefox" — most browsers add this option to the context menu automatically. You can also copy the link address and paste it into the address bar of whichever browser you prefer.
This flexibility means you do not have to change your system default just to use a different browser occasionally. You can keep your preferred browser as the default for most links while still choosing a different one when the situation calls for it.
Frequently Asked Questions
Can I set different default browsers for different types of links?
No. macOS allows only one default browser for all links system-wide. You cannot set Chrome as default for work links and Firefox for personal links. The single default applies to every link you click outside a browser.
Does changing my default browser affect my passwords and bookmarks?
No. Each browser keeps its own passwords, bookmarks, and history. Changing the default browser does not move or copy data between them. Your Safari bookmarks stay in Safari even if you set Chrome as your default.
What if I want to open a link in a different browser than my default?
Right-click the link and look for an option like "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.
Will changing my default browser slow down my Mac?
No. Changing the default browser does not affect your Mac's speed. Having multiple browsers installed uses more storage space, but switching which one is default has no performance impact.
Do I need to restart my Mac after changing the default browser?
No. The change takes effect immediately. You do not need to restart your Mac or close any open apps. The next link you click outside a browser will open in your new default.
