FYI, I just did a test and the goTenna app runs on my M1 MacBook Pro. My goTenna Mesh paired easily with the MBP. After setting up the software for Locations services and such I had to quit the app and restart it on the MBP. It runs fine for the short test that I did. The virtual app screen is pretty small as it can’t be made larger but at least you can type on a real keyboard.
As an aside, I also did a test installing the goTenna app onto my Likebook Mars which is an eBook reader with an e-ink screen running Android 8.1 and that also worked fine with my Mesh.
