Add or remove friends in Find My on Mac
After you share your location with friends, you can ask to follow their locations or remove them if you no longer want to see their locations.
In the Find My app on your Mac, click People.
In the People list, select a name, click the Info button on the map, then do one of the following:
Follow them: Click Ask To Follow Location.
After your friend receives and accepts your request, you can see their location.
Tip: To add your friend as a favorite, click the Info button on the map, then click Add [Friend] to Favorites.
Remove them: Click Remove [Friend] or Stop Sharing My Location.
Note: You can also Control-click a name in the People list, then choose Remove [Friend].
When you remove a friend, that person is removed from your People list and you are removed from theirs.
