Hi, Starting up new MacBook Pro for the first time, had to do something else for 30 minutes during setup. Tried to continue setup after coming back, but got a continually spinning beachball. After 15 minutes it was still spinning, nothing else responding, so powered the machine off and on again. Started setup process again, but now when it gets to the "account name" field it won't allow me to enter my name (it automatically puts a number 1 after it). It appears the first (incomplete) setup process somehow saved the account name so now the machine prevents me from using that same name. How can I start again and use the name I want without having some "phantom" other account name on the machine? Thanks in advance for advice.
