Hi all, I've posted a quick Q on another thread and had a good look around the net, (unsuccessfully), for answers. So thought I'd post anew.
So, I have a Mac Pro 5,1 with the following specs;
Boot ROM is 144.0.0.0.0
Booting via Opencore - Mac OS 10.13.6 build 17G13035 and Windows 10 build 1909 18363.900. Both are on SSDs in the SATA bays.
Normally I use an AMD RX470 and it boots both OS without issue.
With only the Nvidia installed GPU with additional power from a 2x6 to 1x8 pin adaptor, the Opencore selector will come up and I can choose between OSX and Windows but.......
OSX boots without issue using Web driver 387.10.10.10.10.40.137.
Windows is just a black screen.
I have tried it with just the Windows drive in and left for 20 minutes, but no luck.
I have tried all three display ports and the HDMI out but not the DVI, as I don't have a DVI monitor to hand.
With the 1070 and a GT120 installed, the Opencore selector will come up and I can choose between OSX and Windows but.......
OSX boots without issue.
Windows is gets as far as the blue Window on the screen but no progress bar. Weirdly enough when I rebooted with the appropriate card Windows said it was installing a display driver for a 9500. This is with the display connected to teh 120. When plugged into the 1070 it's just a black screen.
Any pointers?
