Hello, thanks for guide!
My system is intel 6700k with hd 530, i also have gt 210 (i know the guide says gt 4xx or newer). I am running high seirra 10.13.3. Hd 530 works out of the box, gt 210 requires inject nvdia set to true or a kext to work. Both work individually, together causes a kernel panic(graphics firmware) ...Can they work together? I use intel to power primary 4K display, i want gt 210 to power secondary monitor. No heavy graphics just text editing! Please give feedback, i will post error later. Thanks for the guide.
Ps. Getting another gpu is not an option.
