I just got my MBA i5 128G SSD running ML and made I guess a big mistake by trying to change my user name which was admin to a prefered name. Found a Apple guide online to do that and succeed doing it .But now when I boot up it ask for my password which is the same but open a different desktop (default it seems)and I can move the pointer but can not click on anything at all except shutting off. Nothing is available to me on all that desktop. I had all my MBA organized as I want to but I am afraid all is lost now. So may be an expert can explain me a way to get it back if at all possible. Thanks a million I do have an other lap MBP to help if needed. Anxious to hear from this wonderful forum.
