Leave a Family Sharing group on Mac
You can only be part of one Family Sharing group at a time, but you (and other family members except children) can remove yourself from a Family Sharing group if you no longer want to participate. After you leave one Family Sharing group, you can join or set up another. However, each person can only join two family groups per year. (Rejoining a family group or creating a new one counts against this limit.)
Children under 13 can’t be removed from a family group. (Age varies by country or region.) See the Apple Support article Move a child to another group using Family Sharing.
On your Mac, choose Apple menu
If you don’t see Family, you’re not part of a Family Sharing group.
Click your name, click Stop Using Family Sharing, then follow the onscreen instructions.
If you leave the Family Sharing group, you keep purchases paid for using the shared credit card, but you immediately lose access to other things the family members share:
Other family members’ items no longer appear in the Purchased section of the App Store and Music app, or the Family Purchases section of Apple Books.
Digital rights management (DRM)–protected music, movies, TV shows, books, and apps you previously downloaded are no longer usable if someone else originally purchased them. Other family members can no longer use DRM-protected content downloaded from your collection.
In-app purchases become unavailable if you bought them using an app someone else originally purchased. You can regain access to the in-app purchases by purchasing the app.
Family members’ device locations don’t appear when you use the Find My app on your Mac, iPhone, or iPad, or on iCloud.com.
