Radeon Compatibility Guide - ATI/AMD Graphics Cards

[RMJ114]

I am having a difficult time booting my USB installer for High Sierra 10.13.3 on my Aurora R7. It acts like it's booting to the main menu of macos installer and the screen goes black and this loses DP connect.

It was recommended I use the section, Note on current AMD cards (3rd & 4th Gen GCN)

but it still does it. All I did was add the RadeonDeInit line and set it true/

I didn't install the lilu as it implied it was part of clover. I have clover 2.4 r4411

I am posting my config.plist in hopes someone can spot my issue.

Thank you for any help.

I have just installed an RX560 in my HP 8300. Made no edits to BIOS/Clover/Kexts as want to keep as stock as possible. A few reboots later and dual displays work, sleep works, but the following don't:

- sound over DisplayPort or HDMI. I use VoodooHDA and I do still get analogue out. I also get 5x "Digital-out (HDMI) in Sound preference pane, but none of them work. This used to work before over DP with HD4000

- I don't have Quicksync enabled and opening FCPX gives a black screen.

I've had a search, and continue to do so, but if you have any hints on the above it would be great - 200+ pages is a lot of reading, and I suspect the recent 10.13.4 has changed things.

- For your on-board audio try the latest lulu.kext + AppleALC.kext (and remove VoodooHDA).
- For DP/HDMI audio, try AddHDMI_8000000=YES to Clover config.plist DSDT->ACPI->DSDT->Fixes
- For enabling quick sync:

• enable IGPU in BIOS,
• add Intel=Yes to Clover config.plist Graphics->Inject
• add ig-platform-id=0x01620007 to Clover config.plist Graphics
• make sure your SMBIOS model type is set to iMac13,2

Using RX 580, and trying to encode a stream with OBS with hardware encoding, my system will lag insanely (to the point where it freezes for 5 seconds, every 2 seconds or so) requiring me to hard reboot. I'm not sure if this is related?

Everything else on my RX works (multi monitor, DisplayPort MST) and I'm not using RadeonDeInit or framebuffer injection any more. SMBIOS iMac14,2.

I tried using 15,1 but I get no DisplayPort output.

Not sure OBS knows how to use AMD GPU on the macOS platform.
It may have a better chance using Intel QuickSync.
Apps have to be use the macOS specific API's to get hardware encoding.

You would have to enable the IGPU in BIOS and set Clover to Inject Intel = yes and set the ig-platform-id = 0x04120004 (connector-less meaning that you cannot connect any screens to your motherboard ports).
With your CPU & IGPU enabled, iMac15,1 is the best match (closest to the real iMac).

I got an MSI RX 470 (Armor 4G OC 4GB) over one year ago, and never got my system really working as it was when I only used integrated graphics (the good old days!)

10.13.4 seems like a good step forward! It properly identifies the card and I get full acceleration. But I still have lots of question, and cannot find current info:

1. is it possible to get sleep working?
2. Should I still use Lilu & Whatevergreen?
3. What should I do with the Intel HD 4000 graphics; shut it off somehow?

Many thanks for any insight.

Thanks. I tried OBS on my macbook and it appears to make use of hardware encoding (not sure if it's using the AMD or the Intel one there). Thanks for the tip about the IGPU, I take it that means my system will be using it to decode/encode rather than the RX? Would this also fix my issue where I can't watch HD content on Amazon Prime (due to HDCP issues)?
Is there no current way of getting the RX 580 to encode/decode?

Furthermore, will enabling the IGPU return my RX's DisplayPort functionality on 15,1 (which works under 14,2 but not 15,1)?

SMBIOS iMac15,1 has AppleGraphicsDevicePolicy issues, special EDID by AGDP and AGDC (MST support, Multi-Stream Transport) enabled by AMD FB and AGPM kexts, both may easy cause black screen, does not support multi monitors. Should avoid to use this SMBIOS even with AMD GPU unless special EDID or MST support is required when monitor higher than 4K.

hey guys
I have 3 cards currently installed.
Nvidia titan x
AMD 7970
AMD RX560

My issue is that after installing the Nvidia drivers, Only the Nvidia card works.
The others show black screen.

Without the nvidia card, The two AMD cards work without issues.

Any Ideas?

Cheers!

Drop in nVidiaFixUp.kext that takes care of black screens most of the time. Also use iMac 18,3 SMBIOS.
