I looked and looked for the appropriate forum, and this one seemed the best. I apologize if the question seems somewhat irrelevant. I don't think it is, obviously. Before she was my ex, my wife and I traded computers. She took my mini and I took the G5. Unfortunately, because the G5 was originally hers, her name is assigned to the top administrator. Worse, the setup procedure included taking her photo, which is also associated with the administrator node. Consequently, her name comes up all the time; the computer is called K____'s iMac and the top level user bears her name, as well. When we traded I was told by Apple tech support that it's impossible to change these original assignments. Is that true?
