Macbook Owners User Name Change
I'm giving my macbook to a friend and have successfully changed the owner's name, following the steps outlined here: http://support.apple.com/kb/HT1428?viewlocale=en_US&locale=en_US
However, when logged in as that user and I want to make changes in System Preferences, when the popup asking for the password to verify/allow the changes, the default username is the old username, despite me having removed that account.
Does anyone have any ideas?!
I can obviously change the username and approve the changes that way, but it would nice for it to default to the new username automatically...
MacBook, Mac OS X (10.6)
