I have a 2009 Macbook pro that runs Mountain Lion. I did not "purchase" it, but I installed it. When I went to make a clean install, I forgot to back up my data through time machine or external hard drive. So I formatted it and I tried to reinstall it but it said i needed an account that purchased lion. I used my aunt's account that has mountain lion that was already pre installed on her new laptop but it wouldn't work. so what do i do?
