Set up the Find My app to locate a missing Mac, device, or item
If you misplace your Mac, a device such as an iPhone, iPad, Apple Watch, or AirPods, or an item attached to an AirTag, the Find My app can help you locate and protect it. Before your Mac, devices, or items go missing, make sure you set up Find My Mac in your iCloud preferences. You can locate and protect your Mac using the Find My app on another Mac, iPhone, or iPad, and on iCloud.com.
For more information about the Find My app on a Mac, see the Find My User Guide.
