I made a really dumb mistake [i think] My short user name was "nic" I wanted it to be a capital. So "Nic" I'm OCD on things like this >.<" I couldn't help myself. [I'm one of those people that hasn't go a single file out of place and whose iTunes library is perfect] I Went to System Prefs > Accounts > Right Click on the account in question And changed short name to "Nic" HOWEVER, I left the home directory as /users/nic thinking it wouldn't matter as it was only a case change. Changing my mind I decided to go back and make it users/Nic Only when I go to unlock to make changes my password is not accepted. My password isn't accepted on the machine as far as I know. I am now too afraid to turn the mini off incase I can't log in! Any ideas ? Running 10.6 by the way.
