I'm trying to follow instructions in the Jan 2011 MacWorld to remove the Ping button from iTunes. I open Terminal and type in the command: "defaults write com.apple.iTunes hide-ping-drop-down 1" but haven't a clue what to name the file when I save itor where to save it so it will have an effect on iTunes. Is there someone out there who is not as clueless as me? I've tried Apple Support, but don't get any results even close to what I'm trying to do. Thank you.
