Hi. First sorry for my English mistakes. I installed a macOS Sierra on a Sapphire RX 460 2GB. As you can see on the picture, it can show up the VGA and the VRAM but it hasn't got acceleration and animations are lagging. I tried the Device ID but no luck. I'm using it with HDMI cable and I disabled the Intel HD Graphics, because the Windows can't boot with it. What can I do for the full support, because I want to use the macOS , not the Windows? Thank you for the answers!
