Radeon RX 560 on 10.13.4 macOS High Sierra

[macs_forever]

Have you tried the patches (method 3 or 4) in the first post? https://www.tonymacx86.com/threads/radeon-rx-560-on-10-13-4-macos-high-sierra.249235/

#3 worked for at least 1 monitor. I'll have to check tomorrow for all three monitors. Then play with Lilu and whatevergreen to see if I can get audio back. THANKS!

Hello,
I've recently switched from GT1030 to AMD Saphire Pulse RX560 4GB OC and have some questions:
Although my card works flawlessly (IMO) with every method listed in post #1, I'm still unclear which method is preferred. Also I only get Acre framebuffer with InjectATI - is this normal?

Could someone advice me do I need Acre framebuffer at all if I only use HDMI (no sound). And last - I'm getting black screen after 50% boot then it goes on at login screen. This happened with every method I use - is it normal for this card?
My IGPU is turned on via BIOS, PEG first.
Here is my Clover/kexts/other, using method #3, not sure if IntelGraphicsFixup is necessary?

I'm still unclear which method is preferred.

I prefer Inject ATI because I don't need DP audio and I would have to disable it with a boot flag when using WhateverGreen.
Acre framebuffer is normal, as far as I understood (see #111)
I've noticed the black screen related to login screen just once, but I usually disable the login screen immediately after installation.
If you don't want to use IntelGraphicsFixup, you should have DSDT Patches: GFX0 to IGPU, HECI to IMEI, PEGP to GFX0 and boot argument -disablegfxfirmware
I've attached my config.plist which has Inject ATI and I'm using with just two kexts: FakeSMC.kext & IntelMausiEthernet.kext

...and I'm using with just two kexts: FakeSMC.kext & IntelMausiEthernet.kext

wow !
I had to "skip" the intel IGP because itunes started to crash incl. weird text all over the menu.
Now I have the RX560 alone and the 3 kexts intelgraphicfix, Lilu+whatevergreen. No problem with sleep or any progy I use...

Maybe I'll give your config + lesser kexts a try.
@ bogdanw Which smbios are you using, iMac 17 or 18 ?

is your AirPlay working?
What is your BIOS settings and what is this boot argument -disablegfxfirmware?
are you just using InjectATI no any method from your post #1?

- I have Intel Graphics enabled in BIOS;
- SMBIOS iMac 18,2 (matches my CPU);
- occasionally iTunes crashes, but I use the alternative version 12.6.4.3 for iOS apps;
- I don't use AirPlay or sleep and I have an USB audio card;
- only PEGP to GFX0 and Inject ATI in config.plist are for RX 560, no other kexts or patches;
- disablegfxfirmware is for iGPU on Kaby Lake, don't think it's necessary for i7 6700K;

Thank you @bogdanw for your response.
Obviously I was wrong saying that my card is working with every method from #1 - Inject ATI working only if I have AppleGraphicsDevicePolicy patch. I've forgot it in my config and in result it booted both with InjectATI and method 3.
Only InjectATI (no IntelGraphicsFixup, + GFX0 to IGPU, PEGP to GFX0 etc) gives me black screen after boot.

I think I'll stick with method 3 and I'm looking for a way to properly inject Acre without clover InjectATI.

That is strange, we have the same CPU & GPU. Do you use a different SMBIOS? I don't have it set in config.plist, as Clover sets it based on the CPU.

Indeed. As per your config I've also checked InjectIntel - black screen, then have unchecked InjectIntel - same result - black screen but computer is working.

I'm using iMac18,2. Here is my config, note AppleGraphicsDevicePolicy is disabled for the test.

 

[bogdanw]

Here is my config

The only difference I see is that you have <key>RadeonDeInit</key> <false/>, I have deleted it entirely.
And change MEI to IMEI is necessary? Take a look at the boot log Patching DSDT:, it might say "already patched!"
