Normally, this would probably be an easy question... I would erase the entire hard drive, reinstall the OS from the disk and be done with it. Unfortunately, because of several issues... A) Losing the Leopard install disk B) Not wanting to erase ALL of the programs I have installed ...erasing the entire hard drive is not an option. Instead, I would like to delete all important things and personal items from the hard drive, leaving all of the programs in tact. I will delete my home folder contents, and my safari bookmarks, and things like that... but I really need to know what OTHER items (such as library items) that I need to delete. Please, help me! If you were selling your mac under similar circumstances, what files would you be sure to delete? Where are those files?
