Here's a weird one. At work I use my iPhone as my music library but listen to it via my Mac with the plugged-in headphones. This always worked great, as I was able to view the library on the iPhone in iTunes with the column browser. The newer Music app doesn't support that. The Retroactive app allows you to install iTunes on later versions of macOS and it actually works and allows me to access my music like before. But, I'm having trouble coming up with macros in KM to do things like pause, play, next track, etc., with the keyboard. It works of course with Music.app, but I can't figure out how to set up controls for iTunes without bringing it to the foreground. Basically, for example, 'Ctrl-Opt-Cmd-Space' pauses and plays music in iTunes, no matter what app I'm currently using. Can anyone think of a way to make this work?
Also completely open to some third party app that would natively allow me to do this.
Thanks.
