With Find My, you can locate and protect your Mac if it's ever lost or stolen. You need to set up Find My Mac before it goes missing. To turn it on, simply choose Apple menu > System Preferences, click Apple ID, then click iCloud. If you believe that your Mac was stolen, contact your local law enforcement.
Use Find My to locate your computer
If you set up Find My Mac before your Mac was lost or stolen, you can use it to locate your Mac on a map, or play a sound to help you find it. You can also use it to remotely lock or erase your Mac. To use Find My, sign in to iCloud.com on another computer or open the Find My app for iPhone, iPad or iPod touch.
Locate your Mac on a map
Open the Find My app and select your Mac from the list of devices to view its location on a map and get directions.
Play a sound
If your Mac is nearby, you can have it play a sound to help you or someone nearby find it.
Lock your Mac
You can use Find My to mark your computer as lost, which remotely locks it with a passcode. You can also display a custom message on its screen.
Erase your Mac
You can use Find My to remotely erase all your personal information from your Mac.
What if my Mac is shut down or offline?
If your Mac is turned off or offline, you can still use Find My to request a notification when it’s located, or lock or erase it remotely. The next time your Mac is online, the actions take effect. If you remove your from Find My Mac when it's offline, your requests are cancelled.
How do I unlock my Mac?
After you locate your Mac, you can unlock it with your passcode on iCloud.com. Make sure to use the passcode that you created when you locked it with Find My, not your device passcode.
Here's how to see the passcode that you used to lock your Mac:
- Sign in to icloud.com/find.
- Select your Mac from the Devices menu.
- Select Unlock. After you follow the steps to verify your identity, you'll see the passcode that you need to unlock your Mac.
You can look up your passcode for a limited time. If you forget your passcode or can't verify your identity to see it, take your Mac to an Apple Authorised Service Provider along with your proof of purchase.
If you can't find your Mac
Find My Mac is the only Apple service that can help track or locate a lost Mac. If you didn’t set up Find My Mac before your Mac was lost, or you can’t locate it, these steps might help you protect your data:
- Change your Apple ID password to prevent anyone from accessing your iCloud data or using other services (such as iMessage or iTunes) from your Mac.
- Change your passwords for other accounts you use with your Mac, including email, banking and social sites like Facebook or Twitter.
- Report your lost or stolen Mac to local law enforcement. They might request the serial number of your computer. You can find this information on the original box or receipt you received when you purchased your Mac.
