Okay, so I'm new to MAC (duh) and have some questions. First off, clips that I watch on Quicktime - are those saved on my hard drive? I don't see anything in imovie, and when I actually open quicktime all I see is promos for new movies. So I'm not sure if that stuff is saved anywhere. But if it is, how do I delete it? Second, is there a way to permanently delete my history? Thanks for the help!!!
