Find My Devices on a MacBook AirSource: Christine Romero-Chan / iMore

Find My Mac is the best way to find and protect your lost or stolen Mac. All you need is your Apple ID, another computer or your iPhone, and you'll be able to locate your Mac, lock it, or erase all of its data.

Here's how to set up and use Find My Mac!

How to enable or disable Find My Mac

You have to set up Find My Mac before your Mac goes missing; otherwise, it's useless. You'll first need to make sure your Location Services are enabled:

  1. Launch System Preferences on your Mac.
  2. Click Security & Privacy.

Now when you sign into iCloud.com on another computer or use the Find iPhone app on your iPhone, you'll be able to find and erase your lost or stolen Mac, as long as it is powered on and connected to Wi-Fi. Just make sure you sign in with the Apple ID that's in use on your missing Mac.

  3. Click Find iPhone.

Your Mac will now show up on the map as a green dot, showing its exact location. If it's really nearby (like you think it might be in your house), you can click Play Sound, and it'll ring out. Though, how you'd lose your Mac in your house, I have no idea. The sound will definitely alert whoever has stolen it that you've found it.

How to Lock your Mac

If you're pretty sure you've just lost your Mac and it hasn't been stolen, but you want to make sure no one tries to access its content, you can lock that bad boy down. Just remember, if you lock your Mac remotely, you can't erase it (which you would want to do if you know for sure that it is stolen).

  1. Go to iCloud.com.
  2. Enter your Apple ID and password to sign in. To find your Mac, make sure you sign in using the same Apple ID that you used on your Mac.
  3. Click Find iPhone.

How to erase your Mac

If you're sure your Mac has been stolen, and you're sure you are never getting it back, you should erase the contents so that ne'er-do-wells that might benefit from having your personal data won't have a chance.

  1. Go to iCloud.com.
  2. Enter your Apple ID and password to sign in. To find your Mac, make sure you sign in using the same Apple ID that you used on your Mac.
  3. Click Find iPhone.
