Make Safari your default web browser on Mac
Safari is the default browser when you first set up your Mac. If you accidentally change your default browser or just want to change it back to Safari, you can easily adjust your default.
On your Mac, choose Apple menu > System Settings, then click Desktop & Dock in the sidebar. (You may need to scroll down.)
Click the pop-up menu next to “Default web browser” on the right, then choose Safari.
Some apps open webpages in a browser other than your default browser.
