Hello, I just bought myself a new MacBook Pro 15" touch bar. After starting it up for the first time and running all the updates, when shutting down my Mac and starting it up again my profile picture now is now showing a black profile user and I'm unable to login using my fingerprint. My other admin user is working fine. However if I login with a password its working but its taking longer than normal to login. Sometimes it makes the Mac crash aswell. What can I do? If I log out then suddenly the profile picture is showing.
