Stop using Family Sharing
As the family organiser, you can stop Family Sharing and disband the Family Sharing group by removing yourself from it. Afterwards, each person who was in your family may be able to join or set up another family.
If your family includes children under 13 (age varies by country or region), you must first transfer them to a different Family Sharing group before you can stop Family Sharing.
On your Mac, choose Apple menu > System Preferences, click Family Sharing, then select Family in the sidebar.
Click Turn Off at the top of the family members list.
If you stop Family Sharing, members keep purchases they initiated and paid for using the shared credit card but immediately lose access to other things the family shares.
Other family members’ items no longer appear in the Purchased section of Music, the App Store and Apple Books.
DRM-protected music, movies, TV shows, books and apps originally purchased by one family member and downloaded by others can be used only by the original purchaser.
In-app purchases become unavailable if they were made using an app originally purchased by someone else. Former family members can regain access to their in-app purchases by purchasing the app.
The family members’ photos album, calendar and reminder list are removed from all family devices.
Family members’ device locations no longer appear in the Find My app on Mac, on iCloud.com or on iOS and iPadOS devices.
