FWIW, I deleted the macro, created a new one, available only when excel is at front. I used a different function key this time. Now it does nothing - which is honestly much better than launching apple music!
I used interactive help now that something expected is not happening. It is telling me that the macro group is not enabled, but it seems to be. I have toggled it on and off and quit and restarted KM and still have the same problem.
