Activation Lock helps you keep your Mac secure if it's ever lost, stolen, or misplaced, and can improve your chances of recovering it. Activation Lock can continue to deter anyone from reactivating your device without your permission, even if you erase your device remotely. All you need to do is keep Find My Mac turned on, and remember your Apple ID and password.

What you need

  • Upgrade your Mac to macOS Catalina.
  • Your Mac must have the Apple T2 Security Chip. You can learn whether your Mac has this chip in Apple menu  > About this Mac > System Report > Controller.
  • Enable two-factor authentication for your Apple ID.
  • Leave Secure Boot enabled on its default setting, Full Security, with 'Disallow booting from external media' selected under the External Boot section.

How it works

When you turn on Find My Mac, 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.

Activation Lock is automatically enabled when you set up Find My on devices that meet its system requirements.

If your Mac goes missing

If you ever misplace your device or think it may have been stolen, you can sign into iCloud.com or use the Find My app to locate your device on a map, play a sound, lock your Mac, or erase it. Activation Lock works in the background to make it more difficult for someone to use or sell your missing device, but you can still remotely lock your device with Find My to secure it with a unique passcode and display a message onscreen for anyone who may find it.

How to check that Activation Lock is on

  1. Choose Apple menu  > About this Mac.
  2. Click System Report.
  3. Click Activation Lock Status under Hardware.

  2. Click Apple ID, then click iCloud.
