How can I unlock my iMac?

After you locate your Mac, you can unlock it by entering the passcode that you created when you locked it with Find My.

If you can't remember that passcode, you have three options:

• Sign in to iCloud.com/find, then select your Mac from the Devices menu. Select Unlock and follow the steps to verify your identity.
• Unlock your Mac from your iPhone, iPad, iPod touch, or Apple Watch using your device passcode.
• Take your Mac to an Apple Authorized Service Provider along with your proof of purchase.

You can look up your passcode for a limited time.
