Solution is insanely simple:
1. In BIOS Features change from default Other OS to Windows 8/10
this step is essential: CSM is configurable only when Windows 8/10 Features is set to Windows 8/10 or Windows 8/10
WHQL
2. Now CSM option is visible and configurable. Change CSM to Disabled.
That's almost all, but wait.
You probably have meanwhile messed with Clover and your your Clover Graphic Configuration is most likely screwed up. Before going on you have to verify if your Clover Graphic section is adequate. Clear every value in Graphic Sectionand leave just ig-platform-id. This value must reflect your actual hardware configuration. For my I3 6300 (HD Graphics 530) i have ig-platform-id 0x19120000. Select yours. Clear all other values.Disregard suggestions to enter "FB name" or "Video Ports" value.Now set "Inject ATI"=TRUE and "RadeonDeint"=TRUE.
Now, that's really all but, still there's more.
Before using your RX580 you have to attain Graphic acceleration on your iGPU and then you'll have just to plug in RX580 and enjoy. To do so, temporary remove your RX580 from the rig or simply disconnect PCIe power cable from your new graphics card. Otherwise, RX580 would hijack your display too early and you wouldn't be able to solve the problem. Reconnect it after you have attained QE/CI and Metal with your iGPU only.If you still do nothave accelerationuse the latest WhateverGreen.kext and Lilu kext. Also verify in Clover Acpi section you have adequate Patches (HDAS to HDEF, GFX0 to IGPU).
Never surrender. That isn't so hard.
NB: I have a slightly different Graphic card: Sapphire RX 580 Pulse (Device ID: 0x067df, Revision ID: 0x00e7, EFI Driver Version: 01:00.3180). However, this method would work for you too.
Sorry I haven't gotten back to you until now, this seems to be an issue that has gotten deeper the more I've dug. I'm going explain my current confirmed situation (after a few days of digging) and restate some stuff over the coarse of a few posts, to make the situation clear to anyone else who may be struggling with a similar situation.
The short of it is that the solutions that you suggested, though I truly appreciated them, have not worked for my setup.
I can't seem to disable CSM or legacy support without negative effects:
I'll post pics of my bios in the bottom, but as it stands now I get no picture when I disable any or all of these or set them to uEFI only.
(which is weird because I disabled them when I installed the os originally with my other nVidia card)
I can't engage my iGPU becuase it's not supported in current MacOS:
I guess only Ivy Bridge HD4000 graphics are supported which are, for desktop, the i5 3470k and i7 3770k
I only have the standard i5 3470
I did however discover both display ports outputs video with no sound in MacOs, but using any other port causes crashes after apple logo and load bar.
