I've searched everywhere. I have ML and I want to go back to Lion, mainly because I'm a student and there is a program called Examsoft that I need to run for exams. There is a ML version but the only reason I can't use it is because my school needs to upgrade their software on their end for it to work. It's a long story and I don't want to bore you guys. I just need to downgrade to Lion. That's it. I bought a MBP last May that came with Lion pre installed. When ML was released I upgraded. I tried to reboot with OPT CMD and R and saw the Lion software come up. However I couldn't reinstall because it said a newer version of the OS is already installed. Please if you have time, provide me with a step by step procedure to get Lion back. I know it may involve reformatting and I'm ready for that. I have no backup image with Lion and I dont use time machine because all my important docs are on Dropbox. I don't really use the HD space for anything except WoW and iTunes as needed. Thanks in advance.
