Hey People!
So, let me tell you a story haha
I run Mac OS 10.7.2 on a 8 core Mac Pro. A while ago, I tried to change my username, but what I forgot was that my 2nd user on the computer has the username I wanted to change to. So I changed my username, didn't get told that it's the same as the other one, restarted, and, well, compeltely lost the access to my files. I tried to go to the settings and change the username back to what it was, but the settings closed a moment after I opened them.
Any idea of what I can do, before throwing cash at the apple store?
Thanks :)
