Hopefully this is the best place to post this question...I need to take my MBA into apple for a screen repair (I have broken glass from a knucklehead throwing something in my direction and it hit my screen). Anyway, lets assume I am running 10.8 which I got from a developer friend, what will be the case? I am not currently a developer and I wanted to know if I need to revert back to 10.7 before I go into apple. Any help would be a appreciated!
