Yes, leveraging the command line argument is the typical approach.

Except I have now discovered that it won't allow me to connect Bluetooth MIDI devices. It crashes as soon as I open the bluetooth configuration window. Among a lot of other things, the error report says,

"This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSBluetoothAlwaysUsageDescription key with a string value explaining to the user how the app uses this data."

EDIT:

It was just a matter of adding my script to list of Bluetooth allowed applications in 'Privacy & Security". Problem solved!

/Applications/Organteq\ 2/Organteq\ 2.app/Contents/MacOS/Organteq\ 2 --fullscreen

and saved it as a workflow in the Applications Folder as 'Organteq_full_screen'

Then go to  'System Settings --> Login Items and Extensions' and add the file 'Organteq_full_screen' to the 'Open at Login' list.

Not sure if this is the approved way, but it seems to work as I want it to. If anyone knows a better way I am all ears.

I am brand-new to my Mac Mini, but am rather familiar with Linux. I would like to be able to turn on my mac and have it come up with Organteq full screen and ready to go. How do I do that?

Thanks!
