I'm using my madiface XT with a MacMini 2018 and since I added an egpu to the setup, Fireface USB Settings prevent the computer from shutting down. Without the egpu everything works fine. The same is true when I shut down Fireface USB Settings before shutting down the computer.

Is this a known issue and is there a solution for that?

Best, Robert
