How to Set Activation Lock on Your Mac (Activation Lock)

By | March 25, 2022

Activation Lock helps keep your Mac data safe, and here’s how you can activate it on your device.

Losing your Mac would be scary but having it stolen would be a nightmare. Your personal information may become available to strangers in addition to losing important files and having to replace computers.

Luckily, the Find My app has Activation Lock, a feature that allows you to prevent your Mac from being accessed or used by anyone but you.

This is an advanced security feature that can really get you into trouble if you want to sell your Mac or send it in for service. We’ll tell you about that and more in the sections below.

How Mac Activation Lock Works

As we just said, Activation Lock is a feature found in the Find Me app. The main function of Find My is to help you find your Apple device if it is lost. With it, you can find your lost Mac or see if You left your Apple Watch at home.

Find My also lets you access your Apple device remotely to mark it as lost or delete its data.

Activation Lock works within this remote access capability. This is a feature that requires someone to enter your Apple ID and password before they can turn off Find My, sign out of your device, or erase and reactivate your device.

This means that when Activation Lock is on, it’s basically impossible for someone to erase and sell your Mac if they don’t have your Apple ID information. It may even be difficult for them to use a Mac that is powered on.

How to Set Activation Lock on Your Mac

Activation Lock turns on automatically when you set up Find My on your Mac as long as your Mac meets certain requirements.

You also need to enable two-factor authentication on your Apple ID and you must have Secure Boot under Startup Security Utility which is set to Full Security.

This is the default setting for Secure Boot, so unless you’ve opened the Startup Security Utility before, you’re good to go. However, if you want to check these settings on a Mac, check out the article Apple Startup Security Utility Support.

If your Mac meets all of these requirements, all you need to do is set up the Find My app to enable Activation Lock:

open System Preferences and open Security & Privacy. Click on tab Privacy and then select Location Services from the menu on the left.

Click the padlock at the bottom left of the window and enter your password. Now, you can make changes in Location Services.

Check the box Enable Location Services which is at the top of the application list. Then, find Find My in the application list and check the box to the left of it. Click the lock again to re-lock the settings.

Now, you have to enable Find My in iCloud. Stay in System Preferences but open Apple ID. choose iCloud from the left menu.

Scroll through the list of apps and check the box on the left Find My Mac checked. Also, click Options on the right Find My Mac and make sure Find My Mac and Find My network both are set to On.

Activation Lock should now be set up and turned on.

You can double check if it is correct by clicking the menu Apple menu > About This Mac > System Report. Under Hardware, click Activation Lock Status and make sure it’s set to Enabled.

Turn off Activation Lock on your Mac

Activation Lock is a great feature to turn on when you have a Mac. However, if you plan to sell your Mac, you need to make sure this feature is turned off.

You’ll also need to disable the feature if you’re sending your Mac to Apple for service. By turning it on, Apple will not be able to fully access the device and therefore they may not be able to repair your computer.

For this purpose, you can turn off Activation Lock by turning off Find My because Activation Lock is automatically enabled in the app.

To turn off Find My, go to System Preferences > Apple ID. Click iCloud in the left menu then click Options next to Find My Mac in the application list. Click button Turn Off on the right Find My Mac and enter your password.

Find My will now be disabled.

If you’ve used Activation Lock and other Find My security features on your Mac, and now your Mac is back, turning off Activation Lock is a little different.

On your screen, there should be a prompt to enter your Apple ID and password. Just type that and Activation Lock should be turned off.

You can also turn off Activation Lock by turning off Find My remotely. You can do this if you forgot to turn off Find My before selling or giving your Mac to someone else.

To turn off Find My and Activation Lock remotely, go to iCloud.com and sign in with your Apple ID. Click Find iPhone and you will be taken to the map window.

Click the drop-down menu All Devices at the top of the page. Select the device you want to disable Find My by clicking on it.

Before you disable Find My, we highly recommend pressing the button Erase [Device] in the window that appears. Doing so will erase all the information on the device, making it fresh and new for the new owner, or clean it up before a thief can access it.

To then disable Find My, click Remove from Account. This will sign you out of iCloud on that device and allow new Apple ID information to be added instead.

There is one other way to turn off Activation Lock remotely. This method is for example you bought a used Apple device but you can’t contact the original owner, and if you have completely forgotten your Apple ID and password and don’t mind resetting your device completely.

open Turn off Apple Activation Lock page and below Need additional support, click the referensi Get Started. You must send your email, device serial number, and details about the original purchase in order for Apple to help you unlock the device.

Your device cannot be in Lost Mode for this, nor is this feature available to non-US customers at this time. However, if you can provide sufficient information and meet these requirements, Apple will update you via email and your device will eventually be unlocked.

Keep Mac Activation Lock Enabled

Activation Lock is a great feature to have in case you ever misplace your Mac or steal it from you. We recommend keeping it enabled on any Apple device to ensure that your personal information remains inaccessible to potential thieves.

There are times when you might want to turn it off and we hope our guide above helped you do that. But for the most part, we encourage you to keep the feature enabled and a little more confident that your Mac is safe even in the worst-case scenario.
