Hi everyone,
I've been running a 5,1 upgraded 4,1 Mac Pro. The graphics card in there is the 6870 which has never been perfect but acceptable. It is running High Sierra at the moment. Thinking of putting Mojave on there but no metal. Linux support for 6870 is also not great.
I got a new Sapphire Pulse RX560 4GB. I thought this was a drop in replacement. No joy. I get a black screen at boot. Never comes up in macOs, or in Linux, or in windows..
Do I need to do any weird Clover stuff to get this working? Or is this card just a dud?
I run my machine occasionally in Debian Linux (and even windows sometimes but don't tell anyone). I use reFind to multi-boot. I have three drives in there, and MacOs installed on a PCI-based SSD.
I'm wondering if the problem is that I'm not booting pure Mac. I am on the verge of doing a fresh install to see. Anything else I can try?
