( Formerly known as High Sierra Media Key Enabler )
Forwards media keys to iTunes or Spotify directly.
You can prioritize which app you would like to control or you can go with the default behaviour which controls the running app. The app runs in the menu bar.
Issues you should know about
The app listens on the event tap for key events. This causes problems in some rare cases, like
when changing search engine in Safari's preferences window
when trying to allow third-party kernel extensions
In these cases simply pause Mac Media Key Forwarder from it's menu.
I want it now!

Apple just released High Sierra and it brought good things and annoying things : they changed the behaviour of the media controller keys, they no longer control itunes, they control the video playback in safari. This pissed off a lot of people including me, so I just created a menu bar app to proxy media key events to iTunes/Spotify while Apple fixes this. It doesn't support touchbar yet, only physical buttons.
