I know this is a bit bleeding-edge, but I just got a new M1 Mac and my USB dance pad doesn’t seem to register inputs, though the “Test Input” settings page shows that the device is present when I plug it in (macOS reports it as visible on USB as well). Actually pressing any of the buttons doesn’t show any inputs being received by the app though.
I did try toggling the Old Joystick Mapping setting (and restarting), no dice. I also verified that the same beta (4.9.1) running on my older Intel Macbook (running macOS Catalina) correctly registers inputs from the same pad, with the same app settings.
Maybe this is just something to do with the app running in Rosetta on the new CPU? Maybe we’ll get lucky and just building for the new architecture would fix this up.
