MacBook pro won't book past gray screen. That loading circle will freeze about half way. Recently changed the ram from 4g to 8gb..and last time I remembered the hard drive was indexing. What ever that means. I don't know why but all of a sudden I've ran into a lot a problems and it's making me hate apple. MacBook pro 6,2 OSX 10.7.2 I believe. I can't access anything else. Im writing from my iPad. I have an appointment at the genius bar tomorrow.
