fingerprint ID stopped working and went dim

"Fingerprint ID has worked for the last 18 months, and then just stopped. I went to systems and the Touch ID icon is not even appearing. How to get it back?"

Troubleshooting Touch ID:

Verify Compatibility:

1. Try this Link: If Touch ID isn't Working on your Mac - Apple Support
2. As it Reads: "Check compatibility: To set up and use Touch ID on a Magic Keyboard with Touch ID, you need a Mac computer with Apple silicon and macOS Big Sur 11.4 or later.

Reset the SMC and your NVRAM:

(Applies to Intel-Based Macs Only): Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Power) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.

“fingerprint ID stopped working and went dim: […]But it immediately went to Apple Logo and the usual start up routine. Again I appreciate your efforts, thanks Kevin”

You are welcome.

So, where do things stand? Are you all set? Or is it stuck at the Apple logo? Or is it something else?

“fingerprint ID stopped working and went dim: I ended up contacting Apple Support. I learned that IMac does not have a way to reset NVRAM. They took me into safe mode, did some things to reset the keyboard, and after that it all started working.”

Great job troubleshooting!
