I have been trying to find a solution on how to remove a single item from the Recent Items menu and not have to clear the whole thing. Before upgrading to El Capitan everything worked just fine. I had downloaded Pref Setter software by Night Productions and used that to edit the /YOURUSERNAME/Library/Preferences/com.apple.recentitems.plist. After the update, I no longer can find this file in the Preferences folder which is probably why Pref Setter no longer works. I would really appreciate it if someone can help me figure this out. I have looked extensively online but have not come across a solution that works. Thanks!
