I erased my mac os x hard drive and tried installed lion again without knowing that I have to use my apple account, and I have forgotten my details for it.
So I held down option and the power button and erased my hard drive to set it back to factory settings for school and I did not know that I needed my apple details to install lion again, and I dont know the username and password for it because I never really used the apple app. I created another apple account but it says I cannot use that account on it.. Please help, what can I do?
