Activation Lock for Mac
Activation Lock is designed to prevent others from using your Mac if it's lost or stolen.
Activation Lock helps keep your Mac secure, even if your Mac is lost or stolen, and can improve your chances of recovering it. With Activation Lock, your Apple ID password or device passcode is required before anyone can turn off Find My, erase your Mac, or reactivate and use your Mac. Even if you erase your Mac remotely, Activation Lock can continue to deter others from reactivating your Mac without your permission. All you need to do is keep Find My turned on and remember your Apple ID and password.
To enable Activation Lock, turn on Find My
If your Mac meets the Activation Lock system requirements, just turn on Find My to enable Activation Lock. It remains enabled as long as you keep Find My turned on. Learn more about Find My.
