"Touch ID not working consistently on MacBook Air: Why is my Touch ID working only about 50% of the time? I cleaned the key, my finger, restarted the computer, etc. Still, sometimes it works, sometimes not. This is happening since latest OS update. Anyone else with this issue? Solution? Ugh...."

Troubleshooting Touch ID:
I. Start Here: If Touch ID isn't working on your Mac - Apple Support
II. f no success...
A. Create New User:
For temporary use, create a new Administrator. See what happens when you log in to it. Do you still get this issue? If not, then is it a misconfiguration in the current user. If so, then you'd likely have to resinstall the macOS.
B. Reinstall the macOS:
Nothing would be lost. It's just that misplaced items would be placed back to where they should be and corrupt system files would be replaced by clean files. Go Here: Reinstall macOS - Apple Support. Important: Prior to installing an update or performing a reinstallation, to prevent data loss, be sure to Back up your Mac with Time Machine.
C. A Bug in the Update:
It might be a bug in the update. Apple might come out with a fix, but they'll only know of this if it is reported.
D. Report this to Apple:
Do your Part: Report this to Apple. Apple may not get back to you directly, but the more feedback Apple receives on this, the more they will know what is going on, and what needs to be fixed in upcoming updates.
- Go Here: Feedback - macOS - Apple
- Select: "Bug Report" for the "Feedback Type"
- Comment: when this all started, and how you have troubleshot it thus far. Include the URL to this thread.
- Proceed from there as necessary
