Hi everyone. I just tried to search for this, but the search seems to be disabled. I have a 2010 13" MBP with Mavericks installed on it that I'm going to sell. I tried following the directions on Apples support page, but the erase options are all greyed out in Disk Utility and it will not let me erase my HD. Can someone point me to the simplest way (I'm not great with computers) to do this and have Mavericks back on it for the new owner? Thanks! - Dave ---------- ooops, needed to hold down command + R. Now it's on the way.
