Hello there :-)
I am very happy if this little tool proves useful to other people and it is great to see screenshots and get feedback on what works and what does not.
As mbolo01 mentioned I have only tested the app with the M5, so perhaps I should add a disclaimer: using this tool is on your own responsibility - should you believe that your $1mio speakers have caught fire and burned down your castle then please don't come chasing me :-)
Jeff, you mentioned a Preferences window. I agree, it would make a lot of sense to have that. In addition to the current settings that can already be configured from the command line it would also be convenient with a checkbox to allow the program to start automatically as a login item. Currently that has to be done manually under System Preferences, Users & Groups, Login Items:

Millemissen, Hiort and kuyttendaele, thanks for testing!
Steve, I will look into releasing an updated dmg-file. Thank you for the excitement :-) I am not entirely sure what NL means, but basically the macOS app mimics what the official iOS app does. I simply looked at what commands the iOS app is sending to the M5 device and then I wrote some code to do the same. This was my first experience with Xcode/Swift and macOS GUI development so I am sure that experienced macOS developers will throw their arms up in the air in despair when looking at the code :-)
Ramasjang, I have not experienced any problems with the current code on macOS Big Sur 11.0 Beta. Is there anything in particular on your mind? Most welcome to continue this topic over on
