Newer Mac computers with the M1 processor require logging in to FileVault with your identifier upon power-up or restart. Newer Mac computers display a single username and password combination on the login page(macOS Sonoma). (Older Mac computers display a list of users on the login screen and accept your UTRGV email address as the username).
Enter your UTRGV identifier [abc123 format] and your password at the login screen.
If the below image is shown on your screen you may create the new account using your UTRGV email address and UTRGV password.
Note: A profile must have been previously added to the computer in order for a user to login.
If a new profile (user) needs to be added, please contact the IT Service Desk.
