Setting Chrome as your default browser in three steps

To make Chrome your default browser on Mac, open Chrome, go to Settings, find the Default Browser section, and click "Make Google Chrome the default browser." That's the whole process — it takes about 30 seconds and requires no restart.

When Chrome is set as default, any link you click outside of an app (in email, messages, documents, or search results) will open in Chrome instead of Safari or whatever browser was handling them before. The change takes effect immediately.

Key Takeaways

  • Chrome's default browser setting lives in Chrome Settings under the Default Browser section, not in your Mac's System Settings.
  • You must have Chrome installed and open to change the setting — you cannot do it from System Settings alone on newer Mac versions.
  • The change applies only to links opened outside of apps; it does not affect which browser opens when you restart your Mac or log in.
  • If the "Make Google Chrome the default browser" button is grayed out, Chrome may already be set as default, or you may need to restart Chrome and try again.

Open Chrome and navigate to Settings

Launch Google Chrome on your Mac. If you do not have Chrome installed, download it from google.com/chrome first.

Once Chrome is open, click the three-line menu icon in the top right corner of the browser window. Select "Settings" from the dropdown menu. This opens Chrome's settings page in a new tab.

Find and click the Default Browser button

In the Settings page, look at the left sidebar. Click "Default browser" — it is usually near the top of the list, sometimes under a "You and Google" section depending on your Chrome version.

On the right side of the screen, you will see a section that says "Default browser" with a button below it. If the button reads "Make Google Chrome the default browser," click it. A dialog box may appear asking you to confirm — click "Open" or "OK" to proceed.

If the button instead says "Chrome is already your default browser," then the change is already done and you can close this tab.

What happens if the button is grayed out

Sometimes the "Make Google Chrome the default browser" button appears but cannot be clicked. This usually means Chrome is already your default browser, or your Mac needs a moment to register the change.

Close Chrome completely (Command+Q, not just closing the window) and reopen it. Go back to Settings and Default Browser. Try clicking the button again. If it still will not respond, restart your Mac and repeat the process.

Verify the change worked

To confirm Chrome is now your default browser, open an email or document that contains a link. Click the link. It should open in Chrome, not Safari or another browser.

You can also check by going back to Chrome Settings and Default Browser — the button should now read "Chrome is already your default browser."

How to change it back to Safari or another browser

If you want to switch back to Safari or use a different default browser, the process is similar. Open that browser, go to its settings, and look for a Default Browser option. Click the button to make it default. On Mac, only one browser can be default at a time, so setting a new default automatically removes Chrome from that role.

For Safari specifically, you can also go to System Settings on your Mac, click General in the sidebar, scroll down to "Default web browser," and select Safari from the dropdown menu.

Why Chrome might not stay as your default

If you set Chrome as default but it keeps reverting to Safari, check whether you have automatic updates turned on for Safari. Some Mac updates reset Safari as the default browser. You can prevent this by turning off Safari updates in System Settings, though this is not recommended for security reasons.

Another cause is if you have multiple user accounts on your Mac. The default browser setting is per account, so if someone else uses your Mac, they may have changed it back. Each account has its own default browser setting.

Frequently Asked Questions

Do I need to restart my Mac after setting Chrome as default?

No. The change takes effect immediately. You do not need to restart your Mac, restart Chrome, or do anything else — links will open in Chrome right away.

Will setting Chrome as default affect my bookmarks or passwords?

No. Changing the default browser does not touch your bookmarks, passwords, browsing history, or any other data. It only controls which browser opens when you click a link outside of an app.

Can I set different default browsers for different types of links?

No. Mac allows only one default browser at a time. All links will open in whichever browser you set as default. Some third-party apps exist that claim to route different links to different browsers, but they are not built into macOS.

What if I cannot find the Default Browser option in Chrome Settings?

Make sure you are looking at Chrome Settings, not your Mac's System Settings. In Chrome, click the three-line menu in the top right, select Settings, then look for "Default browser" in the left sidebar. If you still cannot find it, your Chrome version may be very old — update Chrome by clicking the menu and selecting "About Google Chrome."

Does setting Chrome as default change anything about how Chrome works?

No. It only determines which browser opens when you click links in email, documents, or other apps. Chrome's speed, features, and behavior remain exactly the same whether it is the default browser or not.
