After installing macOS High Sierra, Touch ID just didn't work for me. I was prompted to use Touch ID to unlock my Mac or with supported apps like 1Password and iTunes, but when I placed my finger on the Touch ID button on my MacBook Pro, nothing happened.

Turns out, simply restarting my Mac fixed the issue. Before you do anything, just power cycle your Mac.

How to restart your Mac

  1. Click on the Apple menu logo in the upper left corner of your MacBook Pro screen.
  2. Click Restart.
  3. Click Restart to confirm that you want to restart your Mac.

Once you're logged back in, it should work fine. If not, you can try removing and readding your fingerprint, but don't try this until after you've tried restarting your mac first.

How to remove and readd your fingerprint to Touch ID on MacBook Pro

If simply restarting your Mac doesn't do the trick, you can try removing and readding your fingerprint to Touch ID. Remember: Try restarting your computer before removing and readding your fingerprint to Touch ID.

Remove your current fingerprint registration

  1. Click on the Apple Menu icon in the upper left corner of your MacBook Pro screen.
  2. Click on System Preferences from the drop down menu.
  3. Click on Touch ID.

  1. Hover your cursor over the currently registered fingerprint until you see the X.
  2. Click on the X.
  3. Enter your user password and click OK.
  4. Click on Delete to confirm you want to delete the fingerprint registration.

Repeat this process for all fingerprints that are currently registered to your MacBook Pro.

Readd your fingerprint registration

  1. Click on the Apple Menu icon in the upper left corner of your MacBook Pro screen.
  2. Click on System Preferences from the drop down menu.
  3. Click on Touch ID.

  1. Click on Add a Fingerprint.
  2. Enter your user password.
  3. Follow the prompts to register your fingerprint.

To add your Touch ID fingerprints on a supported app, click on the Apple menu, then select System Preferences from the pull down menu. Select Touch ID. Click Add a fingerprint and add your user passwo (Image credit: iMore)

This should wipe your fingerprint registration and reset Touch ID on your MacBook Pro.

  • I have this problem occasionally, but a reboot hasn't been required to fix it. Simply going into the Touch ID settings and toggling the "Unlock your Mac" setting fixes it.
  • Thanks for the input!
  • For those running High Sierra and having TouchID be slow, I have found a solution (at least on my machine): reset the SMC controller by holding CTRL + ALT + SHIFT + POWER with the computer off for 10 seconds then letting go, leaving it for 5 seconds and powering the computer on. I had also reset my PRAM prior to this and it didn't have any results but it is worth trying the SMC alone doesn't do it (hold CMD + ALT + P + R for 10 seconds then let go and the computer will turn on), and I also deleted my fingerprint and made a new one, again if SMC alone fails. TouchID is now instant on my computer. The problem for me started when I installed High Sierra GM and persisted on the public version.
  • Anyone having trouble not seeing the option for Touch ID in the preferences? I have no problem using Touch ID after upgrading to High Sierra but I was going to go in and add another fingerprint. If I do a spotlight search I see Touch ID listed but when I click on it, it brings up preferences but says "You cannot open touch id preferences because it's not available at this time." Thoughts?
  • Hi, I have the same issue!! Have you found a fix?
  • I have a similar problem. I have a late 2016 MacBook Pro 15" and I use to be able to just unlock by resting my index finger on the TouchId area. Since High Sierra I also have to touch a key or the touchpad to activate. A bit annoying when use to just using my index finger. I turn it off completely everyday so restart did not help he. I have tried to add a finger more - no change.
    Anyone having similar issue?
