iMac-Unable to setup Touch ID on my keyboard.
My touch ID has stopped working. I've tried restarting, updating to the latest OS, turning my keyboard on and off. The Touch ID icon sometimes appears in Systems Preferences and sometimes is missing; sometimes the selections shown in Touch IS are gray/inactive, and sometimes when I start the process of adding a fingerprint print I get the 'unable to startup" message. Is this an issue with the iMac or with the keyboard?
iMac 24″, macOS 12.3
