Well, I use the nvidia without any properties in the config plist, I disabled switchable graphics so I have only dGPU (OPTIMUS DISABLED) It boots but I don’t have acceleration. I understand that it is not fully supported by High Sierra. I asked for properties for the config plist but I guess it’s doesn’t work also.
though as I said it is compatible with high Sierra but no acceleration.
I will try having both, intel+nvidia, but can I run games ? Is the nvidia card going to work at heavy performance? (It is a good old card)
