Auto Unlock Mac using your Apple Watch is a nice feature to avoid entering the password. This feature is available with all Apple Watch but limited to Macs manufactured in 2013 and later. For any reason, if you can’t unlock Mac with Apple Watch, there’s nothing to disappoint. There are certain things to keep in mind to get it to work correctly.
Apart from the pre-requisites, we have also penned down some fixes that may resolve the issue. Before you jump to the fixes, I’ll insist you go through some basic troubleshooting and then move to the advanced part of the post.
Unable to Unlock Mac with Apple Watch? Try below-given fixes
- Make sure your Mac is of 2013 or later model

- You’ll need watchOS 3 or later and macOS Sierra or later to use Auto Unlock
- Your Mac and Apple Watch should have Passcode enabled and set up
Now that you have an idea of pre-required things let’s start with fixes if troubleshooting mentioned above hasn’t helped you.
#1. Disable Automatic Login on Mac
If you have enabled Automatic Login on Mac, you’ll need to disable it. To do so, open System Preferences by clicking the Apple logo, followed by clicking Users & Groups.
Click the lock icon at the bottom-left to make changes, enter the administrator password.

#2. Boot Up Password required for Apple Watch and Mac
When you restart your Mac or Apple Watch, you need to enter the password before you can use the auto-unlock feature. This is identical to Touch ID on iPhone, which requires you to enter Passcode after you restart your iPhone. It is a security feature and not a bug. If you have restarted your Apple Watch, or Mac, or both, you need to enter the password/Passcode for the first time.
#3. Is your Apple Watch Paired Correctly?
To operate different devices flawlessly in the Apple ecosystem, you need to keep basic things in mind. Same iCloud account and proper pairing. Check whether you have paired your Apple Watch correctly with your iPhone.
