SAPPHIRE PULSE RX560 purple screen

[mattiuccio]

Hi guys,
I installed macOs High Sierra on my Gigabyte H370 Gaming WI-FI 3 with i3 8100 Coffe Lake processor and bought an AMD RX 560 for Graphics and in my post installation phase the GPU has been recognized with full acceleration but the display shows purple. The GPU is not broken because in my windows 10 partition it works perfectly. I attached an image .Please help me

try change the Bits/pixel from 32-bit to 24-bit

if you are using Whatevergreen, you may try add this boot-arg : -rad24
* Allows enforcing 24-bit mode on unsupported displays (-rad24)
