Is there a specific .kext that I need to have to make the scrolling work on the touchpad? I also notice that the system does not recognize the touchpad even though it does work totally fine. Just the scrollling..
I have a Dell Latitude e5540 Intel Core 7

What Kexts are you using? Do you have VoodooPS2Controller.kext in your kext folder?

Which kext(s) are you currently using, there are three main kext(s), you should never use two of these main kexts at the same time:
  • VoodooPS2Controller.kext - contains three plugin kexts
    • VoodooPS2Keyboard.kext
    • VoodooPS2Mouse.kext
    • VoodooPS2Trackpad.kext
Rehabman's kext - https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller
acidanthera's kext - https://github.com/acidanthera/VoodooPS2
  • ApplePS2SmartTouchPad.kext - contains two plugin kexts
    • ApplePS2Controller.kext
    • ApplePS2Keyboard.kext
Kext - https://osxlatitude.com/forums/topi...and-synaptics-smart-touchpad-driver-mac-os-x/
  • VoodooI2C.kext - has a supporting kext, (used commonly with newer trackpads)
    • VoodooI2CHID.kext
  • Plus a kext for various trackpads, you use the one that matches your Atmel, ELAN, Synaptics or FTE trackpad.
    • VoodooI2CAtmelMXT.kext
    • VoodooI2CELAN.kext
    • VoodooI2CFTE.kext
    • VoodooI2CSynaptics.kext
Kext - https://github.com/VoodooI2C/VoodooI2C

I have a HP laptop that uses VoodooPS2 Controller.kext but I had to remove the VoodooPS2Mouse.kext plugin to get my trackpad working as a trackpad.

If I left the VoodooPS2Mouse.kext within the main kext the trackpad had only basic mouse options. The trackpad preference pane was empty with no finger swipe etc. options available.

You may find you need to do something similar.

I am checking under System\Library\Extensions and I do not have any of those three listed above. Should I add all three and see what happens? Also, I am struggling to add .kext files to this folder, is there a trick to add .kext files? Sorry, I am still learning this OS.

No do not add all three. As stated in my post above, you don’t want to have two of these main kexts installed at the same time.

Have a look in your /CLOVER/kext/Other folder as you are likely to have one of these kexts installed, most likely VoodooPS2Controller.kext.

@Edhawk Oh ok I see what you are saying. I am having a hard time finding that folder on my installed OS. For that matter I cannot even find my EFI partition, is there anywhere specific I would need to go to to find it?

You need to mount the EFI partition using an app or Terminal command, as it is hidden unmounted during normal operation.

I would recommend you download and install Clover Configurator, which will provide the necessary tools to mount the EFI partition.
