Hi,
I have enjoyed the SoundTouch App on macOS10.14(Mojava) as a Music server Wave SoundTouch Music System IV for a year.
Now Apple released macOS10.15 beta which was changed in the directory structure related music, photo, etc. So SoundTouch App does not work partially on macOS10.15, because I can't set a music library in the App on Mac.
I hope the SoundTouch App is going to be adapted to macOS10.15 soon.
Thanks in advance.
