For MacBook Pro users whose TouchID checkbox to unlock their mac no longer stays checked...<p>If deleting and restoring finger prints, rebooting, and rebooting with the key combo to wipe out the sensor cache all haven't worked for you, try this:<p>Try running "sudo bioutil -w -s -u 1" in terminal.<p>It will wipe out your existing fingerprints, and allow you to re-register, but now the "let me unlock my mac" button will stay checked.<p>Took me forever to find this. Hope it helps someone else.
