Hi mt-fr,
I followed your instructions to install trackpad on Mojave but it doesn't work for me.
I ran Kext Utility after deleting AppleIntelLpssI2C.kext and AppleIntelLpssI2CController.kext from System/Library/Extensions and rebooted with VoodooHDA.kext in EFI/Clover/Kexts/10.14/ folder and no result. Mac keeps booting without touchpad
Everything else is super. Intel HD630, HDMI, Audio, Bluetooth, Ethernet and Keyboard Fn keys are working like a charm! Thanks for all your work.
