hey, my friend just got a macbook from 2010 but it's used and there is a lot of old software, media, etc. on it. The person she bought it from didn't give her the install discs or anything that came with it. What I am wondering is, if I were to use my 2008 OS X discs on her 2010 macbook could I restore the computer to factory settings? Or would I have to use a newer version of the OS X? Please help! thanks in advance.
