Update: everything is now fixed. I have modified @johnnync21 ’s EFI to a fair degree (much is documented in an other thread I posted). I also now fixed multitouch. I may post a guide once I clean up my fixes.

This solved my problem. :clap: Thank you very much for your patience and help.

Yep I was just about to update my last post with that as well. I got this EFI from another user so that kext wasn’t for my system. The webcam problem is taken care of. Do you think that my trackpad not being detected is likely from an incorrect voodoo kext or also from the bad usbports.kext? I...

Thanks for your help. I doesn’t look like it worked :cry: I tried both with Inject set to true and false and each time retyped sudo kextcache -i/ Any other ideas? Update: Trackpad is not working but my webcam is now detected. I was experimenting and added USBInjectAll.kext to /L/E/ and that...

Thanks again for your response. I upgraded to Mojave and have the same problem. Everything works but no trackpad and no camera. I just spent hours trying to fix this including rebuilding, using kept utility, and also patching my own DSDT/SSDT (that ended up breaking everything). I don’t have...

Okay thank you for your quick reply! I installed High Sierra because I thought your EFI was not ready for Mojave (I am using the 1st gen Xiaomi Air Skylake). I need multitouch and webcam for work. Does this work on your efi? Which version should I use? I see your Mojave public beta branch...

I followed his linked guides and I used your EFI but the trackpad isn’t working for me either. Audio works. Also the webcam does not work and shutdown remains incomplete (screen powers off but not the power button light) I rebuilt the cache (sudo kextcache -i /) and I have also copied the kexts...
