I bought my computer from someone and I keep seeing his name in various places like SYSTEM PREFERENCES > USERS and I'd like to substitute his name with mine. I asked someone over at apple forums about this and they told me to open the NetInfo Manager in APPLICATIONS > UTILITIES and to delete him from the users. I did this and after about 5 minutes, the computer shut down and restarted and now I can't log on any more. Luckily, yesterday I created an account with user rights only for my collegue. I used that to log on and from within this account a can still see the previous users' name in SYSTEM PREFERENCES > USERS. The previous users' account has my desktop! i.e. all the stuff I've been putting on the desktop over the last few weeks can be found on his desktop. I cannot access the user accounts, though. If I go to APPLICATIONS > UTILITIES > NET INFO MANAGER > USERS I can see the following: daemon michi (the account I created yesterday) mysql nobody root smmsp sshd unknown www Please help me log on as an admin as I need my computer for my business.
