My mac os x crashed. I have all my disk but I can't get anything accomplished. I pass the screen that ask if us, blah, blah, and when it get to pick the destination......I have no options. This is where I'm stuck. Please let me know what to do. I've been to format, to restore, bring it to the shop....trash it.... I want my computer back up and running. I have all my original disk. I just need to know what to do.
