Ok, that’s really strange. If I were you, I would remove the Alps Kexts and the SSDT-UIAC and see what you get then (rebuild your Kext cache). The touchpad should be recognized as a simple mouse by default and removing the SSDT should let the correct port get recognized. If that works then cross reference the port with the ssdt to make sure it’s configured correctly. Maybe your machine is an anomaly. Otherwise, post your troubleshooting files and I’ll take a look. Seems like this should be easy to solve provided that the touchpad works in windows ok. (Meaning not hardware failure)
Right. I got it at least partially working and it still has some issues I don't like.
I recreated the installer on my MacBook following this guide here and reinstalled. The trackpad worked in the installer which it had done before, but just as before, when I copied clover to efi, kexts to /l/e, rebuilt, and restarted the trackpad stopped just like it had before. It didn't work for me until I put voodoo2lc in the forceloadingkext in clover, re-downloaded and replaced the SSDT, and rebuilt the cache. It worked using the SSDT from the second page and never the one from the first post although I don't know the difference between the two, and I can't rule out a bad download.
Now, though, when left for a bit, a key has to be pressed on the keyboard to make the trackpad work again and there are no gestures at all. Almost like a screensaver is on but the screen doesn't change.
The trackpad is being registered as a simple mouse in settings. No trackpad found. Fun.
But! I'm happy enough to have the trackpad working as it is.
Now, I have to work out nonexistent bluetooth and there's a weird graphics glitch that only seems to show up when a new tab is opened.
It also takes a good long bit for wifi to begin working.
Still, it'll be easier to sort with the trackpad working.
I really appreciate your helping get it going. The Elite makes a great Hackintosh.
