Locate Family members’ devices using the Find My app
When you join a family, you can help other family members locate their Mac, iOS and iPadOS devices, Apple Watch (watchOS 3 or later), and AirPods by using the Find My app. See Set up Find My app to locate a missing Mac.
To locate your family’s devices:
Mac computers must have Find My Mac selected in the iCloud pane of Apple ID preferences.
iOS and iPadOS devices must have Find My app turned on (in Settings > iCloud).
Apple Watch must have watchOS 3 or later.
By default, you can see the location of the devices for each family member. If someone has stopped 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.
Before you can help locate your family’s devices, you must join a family.
