Radeon pro duo 32Gb polaris Compatibility with High Sierra

[siyamalan]

Hi Guys. I just received my Radeon Pro Duo 32GB (Polaris). I hoped that this would be a simple plug and Play on my Mac Pro 5,1 just like RX480. Unfortunately not.

The GPU has one 8 pin (Powered by Dual PCI 6 pin) and one 6 pin (Powered by Dual SATA pin)
Mac Pro 5,1 says Driver Loaded but says " No Kext Loaded"

AMDRadeonX4250.kext in High Sierra GM has this pci device id: 67c4 . Couldn't find anything else
Can anyone point me in right direction in getting this card work with High Sierra

Thanks Heaps

AFAIK MAC OS does not support dual GPU cards.

You can install multiple single GPU cards but not a dual GPU card.

That's unfortunate. This seems to have good render performance for fusion 9

I am having the same challenge. Did you go through with it, have you been able to get it to work later on?
Apple has finally dual gpu`s in operation such as the dual VegaII and the dual 6800xt. So this card here is actually the precursor card to those later dual cards. I`d love to get it to work aside from it being too long. Did anybody scored success with a Frankenstein Polaris Radeon 580 dual Mac driver of some sort?
