Here's the problem: 2011 i7 Air, amazing Machine. I will never sell it. Media keys stopped working with iTunes. 1) When the computer boots, I can control iTunes for few seconds using the media keys on the keyboard. 2) Shortly after, they stop working with iTunes. 3) I believe that the culprit is Spotify. When I open it (I have only iTunes Helper as a startup item), the media keys control Spotify instead, and I remember that that wasn't the case until few days ago. 4) The media keys stop working with iTunes even before I open Spotify. Maybe is there a preferences pane, somewhere, like Vox? How to fix this?
