Hello everyone, I have no experience what so ever with Apples products, especially computers, With windows I'm a wiz and can usually fix anything. My girl friend purchased a Macbook pro in summer of 2012 and loves it, had no issues with it until recently. Having speed issues on the internet and wile using the apple program that's the equivalent to Microsoft word and other small programs. She had no clue what to do so she brought it to her schools free tech support, wile there the kid suggested she bring it back with the OS installation discs so he could reformat it, it did not come with any, so from there she was told there was nothing she could do but go out and purchase the discs.Is it possible that the OS Lion is stored in the computers hard drive or some kind of recovery HD? Can anyone help me out and if its possible give me a step by step walk through to reformat her Macbook? Please someone help!!!! lol Thank you to anyone that can.
