I used to connect my Spektrum DX6i with Aerofly RC7 (running on Mac OS Mojave) without a glitch through an USB adapter (KSIM 4/8/All-in-one).
With RC8, the rudder channel is not recognised anymore (all other channels are ok).
As a workaround, I used ControllerMate to map the rudder channel to the z-axis of a virtual joystick, which is then recognised by RC8.
It works but I would prefer, obviously, to have native support of the output channels of the device.
Can you advise?
