Your default browser opens automatically anytime you click a link in another app.

For example, if click a link from an app (like Slack or iMessage), your default browser is the browser that will open the link. If you always want links to open in Arc, you'll need to set Arc as your default browser.

To set Arc as your Default Browser, go to Arc > Set as Default in the Mac Menu Bar:

When your Mac opens a prompt to confirm, click Use Arc.
