I wanted to transfer my partners files from her MacBook to my MacBook using Migration assistant. Both machines run Snow Leopard 10.6.2. I am administrator on both and she is a user on both. I connected the two machines by Firewire and selected her user to transfer. Part way through the procedure, I got a message saying I could not have two users on the same account with the same name. I aborted the procedure so I could delete her user account on my target machine. But now I can no longer open the account pane in system preferences on my machine. Every time I try, it crashes. I have: repaired disk permissions trashed the com.apple.systempreferences.plist and restarted my machine copied the com.apple.systempreferences.plist from her machine (where I can open the accounts pane) and restarted tried opening the accounts preference pane directly from System/Library/Preference Panes using System Preferences. Nothing seems to work, can you help?
