Hi josecup!
I understand that you'd like to use Touch ID to unlock your Mac, and I'm happy to help. In some situations, it's necessary to enter your password instead of using Touch ID as stated here:
After you set up Touch ID, you can use it to unlock your Mac. Wake up your Mac by opening the lid, pressing a key, or tapping the trackpad. Then place your finger lightly on Touch ID to log in.
Note that you must type your password to log in after you start up, restart, or log out of your Mac. When you're logged in, you can quickly authenticate with Touch ID whenever you're asked for your password.
You can also use Touch ID to unlock these features on your Mac:
- Password-protected Notes
- The Passwords section in Safari preferences
- System Preferences
Note that you must type your password rather than use Touch ID to unlock the Security & Privacy pane and the Users & Groups pane (if you have FileVault turned on).
If multiple users set up Touch ID and log in to the same Mac, they can use Touch ID to switch accounts. Just press Touch ID, and your Mac switches to the logged-in user account associated with the fingerprint.
Use Touch ID on your Mac
Cheers!
