Pete,
More questions.
I've just received my DP-to-mDP cable. The plan was to hook up my current iMac and turn it into my primary display. After more frustrations, I realise that my mac only works Thunderbolt - to - Thunderbolt!!!
So, now my thinking is that I get the Hackintosh up-and-running and stable. I will then sell the Imac to fund a proper screen.
To that end. You said that you used a Sierra installation and then upgraded to High Sierra. What was your experience like in Sierra? What didn't work (as far as the X299 and i7 7800x is concerned)? Help me if I'm wrong, but if I can rather get Sierra working, which to my understanding does support Nvidia, then I can continue with that until High Sierra becomes stable, and then upgrade.
What are your thoughts? I'm struggling to get High Sierra properly working, and I do animation so I need the OS to pick up the graphics card. Will Sierra be a viable option?
By the by, I attended the Super Rugby final! Big Lions supporter. Looking forward to see how we fare against you guys in the Rugby Championships!
Cheers my friend. And thanks for all the advise.
