Locate family members’ devices using the Find My app on Mac
When you join a Family Sharing group, you can help other family members locate their Mac computers, iOS and iPadOS devices, Apple Watch and AirPods by using the Find My app.
To locate your family’s devices:
Mac computers must have Find My Mac turned on in iCloud settings (macOS 13 or later) or iCloud preferences (macOS 12 or earlier).
iOS and iPadOS devices must have the Find My option turned on.
Apple Watch must have watchOS 3 or later.
Each family member can choose whether or not to share their location with other family members in Location Sharing settings in Family Sharing. If someone stops sharing, they must turn sharing back on for you to locate a device. See Stop sharing your location with others in your Family Sharing group.
See Set up Find My on all your devices in the iCloud User Guide.
