The patch I linked fixes the issue you're having due to IASL bug, you might be using a different version of MacIASL than I am.

With that said, you don't need to patch your DSDT for the Fn key for Brightness. I assume you have the Latitude 3480?

Add the 3 patches in those order, you already have the 1st 2 but needs to be reordered, then add the 3rd to your Config file. 

Add the attached SSDT to the Patched folder. Finally, you'll need to use VoodooPS2Controller.kext

Yes am on Latitude 3480, Mojave 10.14.6

I applied the 3rd patch in my clover only as i already have the first two

I put the attached ssdt into Efi/ Clover/ ACPI/ Patched

Remove the appleps2controller from Efi/ Clover/ kexts/ Other & installed voodoops2controller in Efi/ Clover/ kexts/ Other

But still the fn + f11/ f12 key not working

Is there anything i could do?
