Controller showed in Steam, but not in the game

Hello, I use Jumper T16 Pro V2. After connect to my Macbook and set as Joystick I can see it in the Steam Controllers Settings. But in the Liftoff it couldn't see. How to fix it?

Have you checked this support topic?

Yes, I checked, tested and it not working. Currently I installed Freerider and Freerider works fine.

To be clear, have you made sure you disabled generic gamepad support in Steam? Liftoff uses an input plugin that is not compatible with Steam input. Enabling it in Steam will make it not work in Liftoff.
The Jumper T16 is an OpenTX device, so it should work well in Liftoff, even on mac (the Taranis QX7 and X9D+ work as expected on my mac here)

I'm sure that it's disabled and it doesn't help. Not works.

Then I'm really at a loss here :/

EDIT: What firmware version are you using on the remote? Seeing some other people with newer (newest?) firmware (I'm not a specialist on this front) seem to have some trouble still getting it to work reliably.
I know Freerider uses a very basic input solution that isn't flexible in detecting all ranges of values and that Liftoff (and some other sims) use the same input plugin that is more advanced but is more finnicky in working on every system. Perhaps this is still a difference that is at play here and the firmware may be interfering with it.

The guide above drivers that you sent is for Windows OS, but I am using MacOS. I asked my some guys with the same device(Jumper T16) - they said that Liftoff works fine, but on MacOS Catalina. But I want run it on latest MacOS BigSur.
