Izzy Macs are configured to use a custom login window. Most often, these Macs also have FileVault enabled. These screenshots should help you identify the differences between:

1. Microsoft Office 365 login
2. Local login
3. FileVault Unlock
4. Apple Default login

 

 

 

  1. Microsoft Office365 Login screen:

    1. All new user accounts must use this for the first time log on. (Requires your UMICH email address.)

 

  1. Local login or ‘Union’ screen:

    1. for existing user accounts already on the Mac

  1. FileVault unlock screen:

    1. unlocks the FileVault full disk encryption. NOT the login screen

  1. Default Apple login that has been reset by macOS updates.
