Same issue with mine, you can try these: Try to delete and add again the fingerprint Try to hard reset your MacBook (hold down your touchID button until the MacBook shutdown, wait for seconds, then turn it on) If the problem still persists, then Reset SMC https://support.apple.com/en-ca/HT201295 do all the instructions If the problem still persists, then Reset NVRAM/PRAM https://support.apple.com/en-us/HT204063 If the problem still persists, then Try touchID in "Safe Mode" https://support.apple.com/en-us/HT201262 Third-party apps that may be interfering the startup (startup items are probably at fault) and made the touchID not working properly. Back to the normal startup, and I tried to uninstall a third-party app (anti-virus), then touchID work properly. I tried to install it again and guess what, touchID still work like a charm!
