Over the last week, I noticed my Touch ID wasn't responding. Kinda brushed it off as a glitch. But today, I had had enough. I deleted the current print and was going to just set it up again hoping it would fix the issue. But to my dismay, it won't let me set up a new. Keeps erroring out. Yes, I restarted. Sierra version 10.12.4. Saw someone else was also dealing with this. What gives?
