Latitude 7400: trackpad issues

Recommended Posts

Hello folks. 
I have an Lattitude 7400 (successor of 7490) and I'm facing also same problem with making trackpad working under OC. Currently I'm using Clover, as everything working perfect,  I was trying to switch to OC, and it was almost success. The only thing not working was trackpad. Tried many guides but with no luck. sadly, I'm not so advanced in programming, but tried my best. Maybe someone will find a solution for that. :) Fingers crossed.

Good morning. with your config I'm no able to boot. OC gives some "critical error" straight after choosing SSD with Catalina. Below photos of errors. Those regard kexts. I tried several versions, including newest one. no luck unfortunately... :-( I tried to disable VooDooGPIO, then I get error with VooDooI2C.

I was able to boot with my config, using your TDPX file disabling my existing patches , but trackpad working as a mouse. Below picture attached.
