I have a somewhat unique problem. My wife purchased a Macbook Pro with OS 10.9 at the beginning of the year. Unfortunately she hasn't been able to use it until now because Apple uses plastics that give off a gas she is very sensitive to. And this delay has led to a problem, which I cannot work our because I am only familiar with Snow Leopard. When we bought the computer, we ran the standard software to copy everything across from her old G4 desktop Mac. I can't remember now what options I chose, but most of the files seem to be there, and all I thought I had to do was copy across the files she's updated in the last 7 months, which I have done. But when I came to transfer files in her music folder, I couldn't find a music folder on the new Macbook, and I realised there was no users folder either. Then I realised I haven't a clue about the file structure and how user accounts appear in the file structure. I presume she must have a user account to do anything at all, but I don't know where it is. So my questions are these please: 1. Is it possible to be running the computer, have a desktop etc and have no user accounts? 2. If there is no users account, how do I set one up now? 3. If there must be a users account, how do I find it? (The Apple support documentation says search for 'Home' directory, but that search reveals nothing.) Thank you.
