Apple Watch Not Unlocking Mac? Here are the Fixes!

Auto Unlocking your Mac is just one from a ton of really cool Apple Watch tricks. However, it is also the one that most frequently encounters problems. So, if you’re facing this problem, don’t fret because you’re not alone. What’s more, we are here to help.

Before we get to the fixes, I would first recommend you to tick off all the essential requirements for the Auto Unlock feature. If you have forgotten to check off any must-have requirement, the checklist can come in super handy in quickly spotting the missing link. This will save plenty of your time.

Prerequisites for Auto Unlock Mac with Apple Watch

  • Ensure that you have a mid-2013 or later Mac. Folks with Macs earlier than this won’t be able to make use of the functionality.
  • To check whether your Mac supports Auto Unlock, 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. If you don’t see it, your Mac is incompatible.

  • Auto Unlock supports macOS Sierra or later. Ensure your Mac has the updated version.
  • All the Apple Watch models from 0 to 6/SE support Auto Unlock.
  • Ensure that your Apple Watch is running watchOS 3 or later. 
  • Ensure that you have enabled two-factor authentication for your iCloud account. On your Mac, go to System Preferences -> Apple ID -> Password & Security. Now, check if the Two-Factor Authentication is turned on. If not, enable it. As the Auto Unlock feature requires you to bypass your Mac’s login password, 2FA makes sure the authentication is safe.

  • To use two-factor authentication, your iPhone needs to be running iOS 9 or higher. You can enable it via the Settings app -> profile -> Password & Security -> Two-Factor Authentication.

  • Both your Mac and Apple Watch need to be signed in to iCloud using the same Apple ID. On Mac, navigate to System Preferences -> Apple ID to check the Apple ID account. To check which Apple ID your Apple Watch is using, go to the Settings app on your paired iPhone -> Profile.

  • Make sure both your Mac and Apple Watch are passcode-protected. On Mac, go to System Preferences -> Security & Privacy -> General -> Required Password after sleep or screen saver begins. On Apple Watch, open the Settings app -> Passcode. Now, tap on Turn Passcode On and then set up a new passcode. You can also enable it via the Watch app settings.

Once done, restart both your Mac and Apple Watch. On Mac, click on the Apple menu and choose Restart. On Apple Watch, long-press the side button and then drag the Power off slider. Next up, press the side button again to reboot your smartwatch.

If the problem continues to occur even after you have enabled Bluetooth and Wi-Fi, reset the radios. Click on the Bluetooth and Wi-Fi icons to switch them off. Tap on them again after some time to enable.

7. Erase Your Apple Watch and Set It Up Again

If the tricks mentioned above haven’t worked in fixing the Auto Unlock issue on your Mac, it’s time for you to unpair your Apple Watch and completely erase your Apple Watch to set it up again. If you are concerned about losing your precious data, let me tell you that watchOS automatically backs up all the essential data and allows you to restore your Apple Watch from the backup during the setup process.

Just navigate to the Settings app on your Apple Watch -> General -> Reset. Now, hit Erase All Content and Settings and confirm.
