Ok, I was sitting in Biology class and I was deleting some extra junk on my HD that I didn't need. I just got this MBP about a month ago. I somehow put my "Desktop" folder from the HD in the trash, emptied the trash, and all of a sudden, all of my Desktop icons are gone and I cannot add anything to the desktop. I still have a folder in my HD called desktop, because when the "Desktop" folder was in the trash, I tried to drag it out, but it only copied it and still kept a copy in the trash for some reason. I have all my programs that were on my "Desktop" and they work properly if I access them from the HD, Applications file. Now when I try to drag my Safari program from HD to Desktop, it sais "Safari cannot be moved, because desktop cannot be moddified"....WHAT DID I DO???? I restored permissions on my HD and that didn't work. I went to Finder, then Preferences, Sidebar, I re-checked Desktop and click out. I then go to the HD, and on the sidebar, there is NO desktop, and if I go back to Finder, Preferences, Sidebar, the Destop box is un-checked again. I am at a loss here and I realize I am a moron for not paying attention in class and messing with this. Please excuse my stupidity as I am preparing for the worst here.....3rd Party Data Recovery. I sure hope not!
