I have a very simple setup. Mac Mini connected to a TCL Roku TV. I set the A button on the Skip to the TCL and everything works fine. I moved on to set up the B to control various media players I use on the Mac Mini(VLC, IINA, Movist Pro) but I cannot for the life of me find the Device, Brand or Model combo to give me the Apple Keyboard to map to the Skip B buttons. Can anyone point me in the right direction? Thanks.
