Media keys not controlling anything anymore after hardware reset on old Mac Pro
I had to do a hardware reset by turning my Mac off, unplugging, holding power button for 30 seconds, and plugging back in and starting. This fixed the problem I was having but now the media keys on my keyboard only open iTunes when they used to control the last played media. I used to be able to pause YouTube videos and control my music on Plex. I disabled the play/pause button automatically opening iTunes but now it just does nothing. Does anybody know how I can get the last used media functionality back?
