MacBook Pro Touch ID not working!!

I was also having the same issue. Until I followed the steps below. Now it works!

- Shut down your computer.

- Hit "Shift", "Control", "Option" and the power button all at the same time and hold it for 15-20 seconds. Nothing should happen, well, nothing that you will see anyway. (The key combination resets something with the Touch ID)

- Power on your computer normally and login as you usually would...now the Touch ID should work.

I had the same problem, I fixed it - but not without without a hoop or two.
Here's how I resolved my issues (not sure that it'll work for everybody):
I force shutdown (control/option/command Power (all at the same time for about 6 seconds))

On reboot it asked for my password - it didn't recognize the correct password. So, I had to use the FileVault key (I have encryption turned on) to reset my password. I did this but it wanted my old password to continue - this time my computer accepted my old password, I think there's an issue with keychain when you force shutdown (but I don't know). Then I went in to thew TouchID preferences and deleted my old fingerprint (hover over it and an X appears). I'm not sure this was needed, but I did it anyway. I then set up two new fingerprint profiles and now everything works as expected. Will update if strangeness happens. Hope it works for everybody else.

Should point out that I'm on a 15" powerbook running 10.12.6

I had this problem too. In my case, I just added another fingerprint and it solved the issue. I hope it helps.

I had this problem too.

When I first got my Mac, touch id worked fine. Then it all of a sudden stopped working. The touch bar simply did not ask me for a Touch Id, and I had to enter my password each time.

I managed to fix the problem in the following way:

• In System Preferences, Touch ID, I unchecked the "Use Touch ID for:" "Unlocking your Mac".
• Then I logged out.
• Then I logged in.
• Then I checked the "Use Touch ID for:" "Unlocking your Mac" again.

Then it worked again.

I have the same problem. Apple tech support is not able to resolve the issue. They are working on this for last few weeks and still they don't know what they are doing...

They are asking me to do "try this" and "try that", but still no progress in resolving the issue.

Since Apple doesn't seem to help anyone, I will. Apple service has become really terrible lately.

To answer your question, it's most likely a keychain access issue.

1) What I would recommend you to do is delete your current fingerprints and redo them. Reboot and it should work.

2) If the problem persist you could try deleting all your keychains password both local items and logins. Before you do this make sure you remember all your password because this will delete ALL your previously saved password somehow that seems to solve the problem.

i thought in the same way and deleted my fingerprint. But the worst part is now i am unable to add my fingerprint. when i try to add the fingerprint , it prompts for password. But once i enter the password i dont see any other instructions on the screen.

Also , it takes more time to login than usual when i type the password.

Guys help! Besides the fact that I've been unable to add any fingerprint after an upgrade to High Sierra it strated to glitch just like in the pic.

I tried everything, shutting down, restarting, clicking "try again" button, reseted SMC a couple of times... Reinstalled Sierra then upgraded it to High Sierra.

I'm kinda done dealing with a $1750 laptop on my own.

Can apple finally do something about it and address this problem properly?

I just got off the phone with Apple support and there may be a solution to some Touch ID issues...

After a shutdown or restart, you will have to enter a password, that is just a security issue with Apple I'm guessing.

The issue I was having was that I could not swap between different user accounts on my computer...the Touch ID and password option were not showing up so I would have to completely log out of one account in order to log in to another. This may help for some issues:

- Shut down your computer.

- Hit "Shift", "Control", "Option" and the power button all at the same time and hold it for 15-20 seconds. Nothing should happen, well, nothing that you will see anyway. (The key combination resets something with the Touch ID)

- Power on your computer normally and login as you usually would...now the Touch ID should work.

If it still doesn't work, try calling Apple, they were pretty quick and helpful when I contacted them.

This helped me: go the Security & Privacy and check "require password immediately". If it's already checked, uncheck it and then check again.

For some reason it was unchecked for me even though I set it to "immediately" before. I guess something messed up my settings.

I actually just found a solution:

I deleted (clicked on the X) on the fingerprint for the one finger I had registered.

I was then able to register the fingerprint again, and now Touch ID works again! 🙂

Thanks - that worked for me!

Thank you this is extremely useful, it is also important to note that doing this will forget wifi connections, and require you to re sign in to internet accounts in system preferences.

I found the only way Touch ID works to unlock your machine is when you have fast user switching turned on under user and groups options. that feature is turned off by default. once you have that turned on you can click your name on upper right and click log in screen, this will bring you to the log in prompt screen without actually logging out of the computer. from there you can unlock your machine using the Touch ID.. other than that it seems to be unable to do it when you reboot or when you log out and try to log back in using touch id it simply doesn't prompt you on the touch bar.

I bought my Mac 4 months ago, and 2 days ago I did some updates, and after the updates the Touch ID was not asked in the log in anymore. As normal thought I deleted the fingerprint, put a new one, but nothing!

Now I went to the system preferences and in the Touch ID area I unticked all the boxes, restart the pc, went again and ticked all the boxes this time, and restarted once more. After this it's working perfectly 🙂

Hope this works for you guys!
