Dell Latitude 7390: touchpad not responding (Ventura with OpenCoreBoot 0.9.1)

[geo.logic92]

Hello,

 

I've been working on setting up MacOS Ventura (13.5) on a Dell Latitude 7390 (Latitude 7390 - Intel i5 8350U | 16 GB DDR4 | UHD 620 - MacOS Ventura 13.5) and everything seems to work except for the touchpad. I've tried VoodooI2C with the AlpsHID kext and that does not seem to work. Also tried attempting this patch to no avail: https://dortania.github.io/Getting-Started-With-ACPI/Laptops/trackpad-methods/manual.html#osi-to-xosi

 

Touching the touchpad does cause the keyboard backlight to light up but i cannot move the cursor with it. I've attached my current EFI which does not have the OSI patch since I wasn't sure if it was doing anything. Does everything look right?

Hi, pretty sure we've got several threads on this matter for the Latitude 7x90 series. You may also experiment/test the Alps driver I used for my 7490; details are in the guide I had posted in the Guides section.

Yeah I tried looking at and using kexts/SSDTs from a few EFIs on the following threads: here and here and here and also here which seems to use some of your EFI files

 

I also ended up re-adding the osi to xosi patch which still doesn't appear to do anything. Is it possible I need to go to an older version of opencore?

I used @Jazzoo's EFI from https://github.com/CloverLeafBG/Dell-Latitude-7490-OC-Hackintosh.

 

This got things working!!! The one thing I noted other than the difference in the number of SSDT's was that they were using was the fact they were using a MacBookPro15,2 SMBIOS and I had used a MacBookPro14,1 SMBIOS which came out of a suggestion from the Dortania guide.

Glad it worked for you! Enjoy
