When I try to sign on I use the touch ID and nothing happens. Its not even saying retry or anything of that nature. So I'm forced to use my password. I tried deleting the fingerprint and adding a new one, when i did that it, at first, it didn't read my fingerprint. So i deleted the null fingerprint and tried to create a new one and it read it. but then i close the lid an try to log back on and it won't read my fingerprint. Anyone else have this problem?
