For starters, you should know that Touch ID is a sensor built into the Power button. It’s not present on all MacBook Pro models, though. Let’s figure out where you can find Touch ID. On such devices as MacBook Pro 15-inch (model of 2016 and later) and 13-inch (model of 2016, Four Thunderbolt with 3 ports, and later), Touch ID is placed on the right side of the MacBook’s Touch Bar, at the top of its keyboard.

First, you should lift the lid of MacBook Pro and turn it on, or press the power button of Touch ID. Whenever you start up your Mac, restart it or log out, you should log into your personal user account by typing in your password. Having set up Touch ID, and as long as you stay logged into your account, you can use your fingerprints instead of typing your password.

With the help of Touch ID, you can make purchases from all websites that use Apple Pay, as well as from App Store, iTunes Store or iBooks Store.

What to do if you are unable to complete Touch ID setup on MacBook Pro?

Reportedly, many users have faced different types of problems in the work of Touch ID on a MacBook Pro. One of the most common issues is being unable to complete the setup process of Touch ID. Often, this may happen after an upgrade to the latest version of Sierra. Otherwise, you may lose the actual fingerprints due to a system crash, or a bug in the work of the Activity Monitor.

In case you have faced one of these problems, we recommend you to delete your fingerprint(s) which you’ve created during the initial Touch ID setup. After this, you can go to Touch ID Preferences Pane and add new fingerprint(s).

To delete the fingerprints:

  • Hover the pointer of your mouse over the already existing fingerprint. In a second the delete (X) button appears.
  • Click the X button. Next, enter your user account password to be able to remove your fingerprint.

To add new fingerprints:

  • Place one of your fingers on the power button of Touch ID; simply hold your finger but don’t press it. Hold your finger down until a prompt asks you to lift it up.
  • Lift your finger slowly and rest it. You can make some adjustments as to the position of your finger every time you use Touch ID.

How to reset Touch ID on MacBook Pro?

Some users’ devices only ask to enter their user account password but have not requests for their fingerprints. If you stopped getting prompts to use Touch ID on your MacBook Pro running on Sierra, we recommend resetting it.

To reset the fingerprints, you have to delete the existing one(s) and set up the new one(s). Follow same steps as described above in the article: how to remove old and set up new fingerprints.

  • Shut down your MacBook Pro; make sure that its screen is off.

  • After, MacBook Pro will restart itself. Press the power button if it didn’t.
