For MacBook Air and Pro users, the Touch ID can be a perfect option for you to unlock your Mac laptop more easily and conveniently.
However, MacBook Air or Pro Touch ID isn’t working suddenly. Many of you tried to use the fingerprint to activate the Touch ID, only to find that Touch ID stops working after updating to the macOS Big Sur.
Hence, numerous users reported that on the Mac Magic keyboard, the Touch ID doesn’t work on MacBook Pro or Air.
Like the error of the MacBook Pro Touch Bar not working, this MacBook Touch ID not functioning error is rather frustrating.
Fortunately, this post can help you thoroughly troubleshoot this MacBook Touch ID error, including the case where you encountered MacBook Touch ID not working while you are charging the MacBook.
What Does Touch ID Do? Where is the Touch ID on MacBook Air and Pro?
The Touch ID, usually the power button, locates in the upper right corner of the Mac keyboard. The Touch ID works when users use the fingerprint to unlock and lock the MacBook, make purchases from App Store, Apple Books, and many other Apple applications.
Like how users use the Touch ID on iPhone 5s through iPhone 8 and 8 Plus, the iPad mini 3 and later, the iPad Air 2 and later, 2017 and 2018 iPad models, and 2015 through 2017 iPad Pro, the Touch ID gains favor from many Apple fans.
What is the Right Way to Use the MacBook Touch ID?
Perhaps you just have no idea how to use the Touch ID on MacBook, so odds are that you “find out” that your MacBook Air Touch ID isn’t responding even if you put your fingerprint on the right location as mentioned above.
If so, before bothering to try solutions to fix this Mac Touch ID not working issue, learn how to use it correctly.
If you are using the MacBook Touch ID for the first time, for instance, when you have just bought the Mac laptop, you need to use the password and then add the fingerprint in System Preferences > Touch ID.
If you have added your fingerprint before, you need to try to cover the Touch ID completely to get your fingerprint recognized by the device. Don’t use the wrong finger to use the Touch ID, which will not activate the Touch ID. It is the finger that you have added that enables you to unlock the MacBook with the Touch ID.
Your Touch ID won’t work naturally if:
1) You have tried to use the Touch ID five times consecutively but the fingerprint just failed to be recognized;
2) You have not unlocked the MacBook Air or Pro for over 48 hours,
Therefore, try to learn how to use the Touch ID properly and learn about normal cases where your fingerprint isn’t working out of Apple’s security alerts. If you are sure that you have used the Touch ID correctly and the Big Sur Touch ID just doesn’t work, move on for specific solutions.

For many of you, the error that Touch ID doesn’t work on macOS Big Sur will have been resolved after the system update.
Solution 3: Delete and Re-add the Fingerprint
In case your Touch ID fails to work due to the problematic fingerprint, you can just try to add a new fingerprint to set up the MacBook Touch ID again.
