Requirements to enable Auto Unlock Mac with Apple Watch

Before you can use Auto Unlock, you'll need to make sure that your Watch and Mac are compatible and up-to-date. Make sure that your devices meet these requirements:

  1. Your Apple Watch is running watchOS 3 or newer.
  2. Your Mac is running macOS Sierra or newer. If you're using Apple Watch Series 3 or newer, your Mac needs macOS High Sierra or later.
  3. Both your Mac and Apple Watch are signed in to the same iCloud account, and your Apple ID is using two-factor authentication.
  4. They both have set up a passcode.

Still not sure whether your MacBook Air or MacBook Pro supports Auto Unlock with Apple Watch? You can press and hold the Option/Alt key while selecting the Apple Menu > System Preferences. Now, select the Wi-Fi option in the sidebar and then locate the "Auto Unlock: Supported" on the right. It means your Mac supports the Auto Unlock feature.

If you can't find "Supported" besides the Auto Unlock option, then you can't use Apple Watch to unlock your MacBook.

  3. Open Security & Privacy and click on the General tab at the top of the window.enable unlock Mac with Apple Watch

Now you should be able to unlock your Mac just by wearing your Apple Watch when you wake it. But, for the first time you log in after you turn off, restart, or log out of your Mac, you'll still need to enter your password manually.

Bonus tips: Approve other Mac password requests with Apple Watch

If your Watch is running watchOS 6 or later, and your Mac has macOS Catalina or later, you can also use the Apple Watch whenever you're asked to enter your Mac's administrator password.

It means you no longer need to type your Mac password when viewing passwords in Safari preferences, unlocking a locked note, approving an app installation, or unlocking settings in System Preferences.

For example, when you click the padlock icon to make changes in System Preferences, your Mac will ask you to approve with Apple Watch or enter a password.

To automatically enter your password without typing it, you just need to double-click the side button on your Apple Watch. Isn't it magic?
