Latitude 5480 Trackpad issue on Catalina


Recommended Posts

Hi everyone, I have been scouring for a resolution to this trackpad not working issue and some of the promising posts the attachments were unavailable. I am running Catalina with OpenCore. I have the voodooI2C kext and the DDST but it still isnt working. Not sure if I am missing something in my config.plist or what. If someone could take a look and point me in the right direction it would be appreciated, thanks.

@Jake LoI've used the above ACPI patches on my 5480 and it's got the trackpad working under Big Sur however it's showing up as a mouse rather than magic trackpad with only 2 finger gesture working - is it a limitation of my trackpad or can I do anything to get it going? my touchscreen is being emulated as a magic trackpad - could that be causing issues?

@Jake Lo I added the kexts and ssdt and replaced config file and it fixed the trackpad but broke the keyboard...   lol  I reverted everything back so i have keyboard again but no trackpad using my original EFI and config.plist.

 

I also just realized my audio does not work
