When I run 5.4.2-38-g106390a9 I get error message "NO DEVICES FOUND".

I tried to press "M" and "+", and then the options "auto", "all", but it doesn't work as I get another error message:

I'm using a Mac with OS version 10.14.2. When I plug in the moonlander2, I don't see it on my mac under devices. The moonlander2 has a solid green light on.

Pls, help!
