Thanks

touch pad is now working. though had to install Trackpad.prefPane from Sierra to detect trackpad in os preferences. now gestures including double-click works

 

mouse still doesn't work.

any way of injecting wx3200 to make it work?

I Have injected wx3200 with Radeon Pro 560 and running successfully

have you got sleep wake working? I have my 7450 mojave and catalina fully working, but sleep and shutdown result in reboot. all the rest works like a real macbook pro. Although I had to disable the Nvidia card ( rtx3000 for which there are no drivers published from nvidia even for HighSierra)  currently running -wegnoegpu with nvidia gpu disabled through hotpatch. but sleep doesnt work, and shutdown results in reboot. using MacBookPro 15,1 at the moment ( tried 15,2 - 15,3 and 16,1 with varied results but always sleep and shutdown result in reboot.

 

tried removing powermanagement files, but no go.

 

edit: small update, seems to be a system issue, as windows and linux behave the same as OSX, sleep=crash-restart shutdown=shutdown and reboot after 10s with entry in bios log, power-on reason: unknown.
