The first time you log in to a newly configured Mac, you will need to sync your account credentials using the NoMad application:
1) NoMAD is the triangular icon in the top bar. Click it and choose "Sign In". Use your netid and password.
2) You will get the message below that your passwords are out of sync. Provide the temporary account password from Tech Services in the box as shown.
3) When the account is successfully synced, the NoMAD icon will now have a check mark and you'll see new options in the menu.
