Hello all I have a Mac that has this weird problem. It's a used Mac and I've no idea what the previous owner did. This Mac has a 750GB drive but the OSX partition only has 100GB. Disk utility doesn't recognize the entire disk so there's no way for me to resize the OSX parition. All I want is to perform a clean re-installation of OSX onto the entire 750GB drive and but since disk utility only recognizes the 100GB I'm unable to do so.
Can someone help me? I can work with Terminal commands if that will fix the problem.
