Hi Jake, used the IOReg from the one you linked in the previous page.
 
	 
 
	Catalina, OC 0.5.9
 
	I haven't patched SMBUS though via SSDT though, and I'm not sure if that's gonna affect my IOReg output
 
	 
 
	Edit: Forgot to answer your question
 
	It is an elan ps2 touchpad, but I'm not sure if there's an SMBUS connection I can hook into.
 
	The gdrive link with the jumping cursor upon gestures is my video which I posted on reddit.
 
	 
 
	Edit 2: I've tried all 4 kext versions. V1 actually works well for my gestures ! I didn't patch smbus or anything. Since my touchpad is elan V4 touchpad, I believe something was added in the version 2 of the kext, probably about accommodating v3 touchpads.
