Locate devices, even if they’re offline. Find My uses Bluetooth signals from other nearby Apple devices to locate your device when it’s not connected to a Wi-Fi or cellular network. These signals are anonymous and encrypted, and help locate your missing device without compromising privacy. You can even find a device that’s been erased (for Macintosh computers with macOS 12 or later, iPhones and iPod touch devices with iOS 15 or later, and iPads with iPadOS 15 or later).
Find a family member’s device. You can use Find My to help locate a family member’s device, if you’re in a Family Sharing group and your family member is sharing their location with you.
Find everyday items. Attach an AirTag to an item like your keychain to quickly locate it when you can’t find it. Use your iOS or iPadOS device to register an AirTag and compatible third-party items to your Apple ID. To locate items using your Mac, click the Items tab in Find My, then click an item in the list to view its location on the map. If the item can’t be located, you can view its last location and receive a notification when the item is found. You can even turn on Lost Mode for an item that includes a message and phone number.
