VoodooSMBus VS WhateverGreen

Keyboard (VoodooPS2), TouchPad (w/gestures) and TrackPoint (VoodooSMBus)

Are you sure your touchpad is only PS/2? (check here) You may also need VoodooRMI, VoodooSMBus, and/or VoodooI2C (and its plugins).

Oh, there's your issue, you were using the wrong drivers from the beginning, remove the driver that you were using before and install this one

For touchpad use this : https://github.com/VoodooSMBus/VoodooSMBus

Read the "Installation" section in https://github.com/VoodooSMBus/VoodooSMBus, but ignore all the directions regarding patches. Instead, do this in OC-Configurator:

And finally, one last fix i needed to make all 3 screen working (before only 1 was working), was to replace the kexts with the newest version: https://github.com/acidanthera/WhateverGreen/releases

(from https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md)

Intel HD 520 graphics - WhateverGreen, AAPL,ig-platform-id = 00001B59 , device-id = 16590000

If so, refer yourself to Intel iGPU Patching guide and WhateverGreen patching manual.

I went to this site from the dortania opencore guide https://github.com/acidanthera/WhateverGreen/releases And I downloaded the 1.5.9 version I copy the kext file and I replace the old file with the new one in the kext folder.I have an amd gpu but I think there is hope.

Only other things I would check would be the BIOS settings. Otherwise you may need to work through the Frame buffer patching guide

Check this, there is more information about patching with whatevergreen.
