If you just downloaded or updated to the new iTunes 10.0.1 for Mac OS X, then you’ll notice that in your library, next to every song (when selected) there’s a drop-down menu called “Ping“. It looks like this:

Disable iTunes 10.0.1 Ping Drop-Down

New iTunes 10.0.01 update Ping dropdown (Mac OS X Snow Leopard)

It shows even if you don’t have a Ping profile, and when you click it—it shows options to “Like”, “Post”, “Show Artist Profile”, “Show in iTunes Store”, etc. This new menu is similar to the iTunes Store arrows (which it seems to have replaced). There’s no option in the iTunes Preferences to remove this functionality.

So, how do I hide the Ping drop-down? Easy. As reported by a user on Apple Discussions, all you have to do is:

  1. Open Terminal (search in Spotlight or go to your Applications folder)
  2. Copy and paste the following, and press enter:
    defaults write com.apple.iTunes hide-ping-dropdown -bool TRUE
  3. Restart iTunes, and the Ping drop-down in your library will be gone!

To undo this (make it come back), simply do the same, but instead use:
defaults write com.apple.iTunes hide-ping-dropdown -bool FALSE

That’s all folks. Now tell your Mac-user friends!
