Radeon Compatibility Guide - ATI/AMD Graphics Cards

[qbe]

Running 10.13.4 (17E202) and the DPs working with SysDef iMac14,2 with RadeonDeInit=No (false) and w/o Luli & WhateverGreen kexts. Power management per Intel Power Gadget is being managed so no SSDT required for PM. Looks like I/we found the answer for using RX 580s which in my case is a Sapphire Pulse 8GB graphics card.

can you run dual screen? (one of those screens DP?)

Yes. All my ports are working with two monitors. I've tested 2x DP, 2x HDMI, DP and HDMI, DVI and HDMI and DVI and DP.

Hopefully, use of the 18,3 will get fixed in 10.13.5.

I'm running a Vega Frontier Edition on a Dell T5500. It works OOB for one monitor, but I can't get it to support dual monitors. Any help? I'm running iMac 14,2 for my system and I've used Clover Configurator to manually type in the frame buffer "Kamarang" and checked off "RadeonDeInit". Still can't do dual monitors. I am trying to do 2xDP but I did try 1xDP and 1xHDMI and that still didn't work. My screen goes milky grey and my other monitor interprets a signal but just stays black.

Use 10.13.4

Remove RadeonDeInit
Remove WhateverGreen

Add VegaGraphicFixup

Thanks for that. Unfortunately, it doesn’t work, but on a good note instead of freezing at the boot screen and turning gray it gives me the black screen with the Apple and loads to 100% then gives two black screens.

I installed the kext along with lilu 1.2.3 in /S/L/E and updated the kext cache...should I install this in the EFI partition’s “other” folder?
I removed RDI and didn’t have WG installed.

And I’m on 10.13.4 with the latest update.

I have a 7950 incoming (bought second hand). Is there any issues I need to be aware of? like non-working HDMI audio. or DSDT patch and etc.

Thanks

Yes use /efi/other as much as possible.

I have a Vega FE but I use the iMac Pro SMBIOS based on this guide which is more complicated to set up and for X299 boards.

Can you post your system specs?

Please provide complete details in your Profile per the Forum Rules.

Mobo: motherboard manufacturer/model
CPU: detailed CPU model (e.g., i7-4770K)
Graphics: Video card manufacturer/model and/or Intel Integrated Graphics version (e.g., HD4600)

See my Profile items to the left of my post, under my name.

Gotcha, done.

Updated my specs. I'll take a look through that guide and see if I can piece anything together. I moved the kexts to /efi/clover/kexts/other and still end up with the same result. My system is set up as a late 2013 iMac. Perhaps I should try an iMac Pro?

No, Mac Pro 5,1 is better for your system. Or Mac Pro 6,1.

Then with 10.13.4 Vega FE will work OOB.

You MAY want to try WhateverGreen just in case if it doesn't.
