You Do Not have Sufficient Privileges is a message I get when trying to save anything to my Desktop. I was simply trying to save some pictures from my SD card to the desktop for quickness and the msg says - 'The item 1234.jpg could not be moved because "desktop" cannot be modified.' I click the button "Authenticate" - then get "Finder requires that you type your password". Click Ok and get "The operation cannot be completed because you do not have sufficient privileges for some of the items". Any ideas on how I resolve this one?
