Tip 1: Bluetooth and Wi-Fi Must be Turned ON on Mac

To unlock Mac or MacBook using Apple Watch, you’ll need to enable Bluetooth and Wi-Fi on Mac. In case, disabling and enabling the “Use your Apple Watch to unlock apps and your Mac” on MacBook, the system will ask you to turn on Wi-Fi and Bluetooth and after that, you can use the auto-unlock feature on Mac.

  1. Click on () From top Apple Menu.
  2. Go to System Preferences.
  3. Then choose Security & Privacy.
  4. Click on the General tab and then check the box of “Use your Apple Watch to unlock apps and your Mac”.
  5. If the pop-up asks you to Turn On Wi-Fi & Bluetooth, click to enable them.

Tip 2: Bluetooth Should Be Enabled on Apple Watch

Just like, Wi-Fi and Bluetooth need to be enabled on MacBook, both of them should be enabled on Apple Watch too, or at least make sure to turn on Bluetooth on Apple Watch. To establish a connection between Apple Watch and Mac, the Bluetooth is to be turned on.

If Apple Watch isn’t connected, it will show RED symbol just like this.

Tip 3: Both, Apple Watch and Mac must be logged in with Same Apple ID

This is a very silly mistake people often make when they bring a new Apple Watch or switch to a new MacBook. Always use the same Apple ID across iPhone, Apple Watch and Mac to get the most out of the Apple devices. Similarly, if you want to use auto-unlock, but unlock Mac with Apple Watch no longer working, then make sure to verify the Apple ID on Apple Watch as well as on Mac.

  • For macOS Mojave or Earlier: Apple Menu > System Preferences > iCloud > Account Details > Security.
  • For macOS Catalina: Apple Menu > System Preferences > Apple ID > Password & Security. Check the Apple ID as shown in the following screen.

Or you could directly check the devices that are currently signed in with the Apple ID right on the iPhone. Go to the Settings app > Tap on your profile name > Scroll down, all the devices are listed including Apple Watch and Mac that are using the same Apple ID.

Tip 4: Apple Watch & Mac Should Be In The Range

Since the auto-lock function requires Bluetooth and Wi-Fi to be enabled, we’ve assumed that if unlock Mac Mojave stopped working with Apple Watch or Apple Watch won’t unlock MacBook Pro, the distance between Apple Watch and Mac to be considered. Make sure both Apple Watch and Mac are in range and then try to unlock Mac with the Apple Watch.
