What to Do if MacBook Pro Touch ID Stopped Working on Sierra?

In this article, you will get to know about working principles and functions of Touch ID on MacBook Pro, and the most common issues that may occur with this fingerprint recognition tool. Follow our tips to fix Touch ID it won’t set up or fails to work properly on macOS Sierra and High Sierra.

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.

Let’s get started

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.

Before you start, make sure that your fingers are dry and clean. Moisture, sweat, lotions, skin cuts, etc. may affect the recognition of your fingerprint.

  1. Go to Apple menu, and open system Preferences.
  2. Click the section Touch ID.
  3. To add a fingerprint, click the + (plus) sign. Once you see a prompt, type in the password of your user account. Stick to the following on-screen instructions.
  4. Check in the boxes with the features that you’d like to use with the help of Touch ID.

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.

If your Mac became irresponsible due to being unable to scan your fingerprint, the following steps might help:

  • Shut down your MacBook Pro; make sure that its screen is off.
  • Reset the device’s SMC memory. To do this, press the keys Shift, Option, and Control while holding the power button down. Keep holding all three keys and the power button down for 10 seconds.
  • After, MacBook Pro will restart itself. Press the power button if it didn’t.
  • Launch the preferences pane of Touch ID.
  • All previously existing fingerprints will be deleted by default. Now, you can add new ones.

We hope that our recommendations will help you in fixing issues with Touch ID on your MacBook Pro.
