Thanks a lot @MakAsrock & @LockDown

I am using gigbyte MOBO if that makes any difference.
Tried no luck.

This is so annoying, Tahoe 26.0 worked flawlessly, then 26.1 and 26.2 have become nightmare.

Any other solution?

RX580 GPU has 2 display port and 2 HDMI port, if that helps.

Don't try to use my configuration directly. You'll need to adapt it to your needs, especially the ACPI patch section. I've provided it as an example only.
My card has Outputs: 1x DVI-D, 2x HDMI, 2x DisplayPort. But I don't use DVI-D.
If you have an AMD Radeon RX 580 2048SP, it won't work in Mac OS without flashing the correct vBios. It's not really an RX 580, but an AMD Radeon RX 570 or even an RX 480.
I also had an ASUS DUAL RX 580 8 GB, which also wouldn't work.

The Gigbyte MOBO was a great platform for Hackintosh, but it's long since become obsolete. It has its own unique features, unlike the Asus, which was a real headache for me due to its BIOS until I flashed it with a programator. But it was problem-free in terms of USB ports (less than 15 and only Intel).

My RX570 worked in 26.1 but had a problem in 26.2. The problem was somehow resolved after reinstallation.

Try also flash vBios by newer version with UEFI GOP, it may influence.

Thanks @Slice

any link to - Flash vBios by newer version with UEFI GOP

& @MakAsrock
I think I did the video flash (the card is XFX Rx580), and it was working till Tahoe 26.0. So if I need to flash with something newer, please share the link to the FW..

The card is the XFX Rx580, one of the best cards for Hackintosh and runs macOS 26.2 out of the box, just like the Sapphire Rx580. There's only one problem: It doesn't work with all MOBOs. But it does work with yours. It requires precise alignment of PCIe lanes.
UEFI GOP may need an update, but I doubt there is a newer one than yours.

You can search here. But be careful, you can make a brick out of your card.

In any case, I advise you to save the stock vBIOS in a safe place.
So the problem is in the config. Try updating and adapting this one.

I have no clue what needs to be done

From Hackintool, the info is as below

@vamose

According to @MakAsrock, your XFX Rx580 works fine (like my MSI Radeon RX580 8Go OC). Update vBios seems to be unnecessary.

PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) is correct instead fo your entry in config.plist. Why this incorrect entry is setting to disable ???

help me what needs to be done. I have followed guides blindly, so I do not know the logical reasoning behind.

Help is needed..

So, you need to disable this:
00:01.0 8086:0c01 /PCI0@0/PEG0@1 = PciRoot(0x0)/Pci(0x1,0x0)
And try the new Lilu-1.7.2-RELEASE fix, which enables the use of WhateverGreen.
I hope it works out for you. 😉

I'm sorry, but I was mistaken.
You don't need to disable anything.
The integrated video controller isn't showing up in the device list, which means, like mine, the RX580 automatically disables it when installed in the first slot.
Just update WhateverGreen and Lilu.
Later, I'll edit pcidevices.plist for you.

And yes, all 8GB RX580 cards already include GOP. RX580 4GB cards may not.
So don't flash anything.

thanks for the guide. Update .kext as per latest available, no go.

in regards to PCIDEVICES.plist, where & how to use it?

Just copy the "add" section and paste it into your config. 😉
But before that, I would do RX580 init first in the BIOS and reduce the shared memory for the integrated card to 0 and disable CSM compatibility.
At the same time, the PCIe bus number for RX580 may change.
Everything works the same for me, I just deleted the partition with Tahoe because of the very slowdown.

Thebes Knossos · January 16

Hi, I still have problem for full or delta updates on both computers for Tahoe (no dev releases need only regular ones)

Example here on the Haswell PC, it was installed without problem with SMBIOS MacbookPro16,1 .

Attached my actual Opencore EFI, config.plist is cleaned with latest with OCAT

Tested with Opencore 1.0.5 and 1.0.6 (actual 1.0.5)

OCLP is removed, so no Audio, no Wi-Fi nor metal lib but I don't think that's the problem for updates..

It's same EFI for Sonoma and Sequoia and for them I get delta updates.

If someone can have a look, would be nice!

Thanks

Let's see how the issue of the Taboe error in updates or beta installations when using Radeon is being addressed. Currently, there's a modified kext, which is the one I use, WhateverGreen.kext v1.7.1d7, that works perfectly. However, an unofficial kext, Lilu.kext v1.9.7, has appeared that claims to work and use the official WhateverGreen. This problem hasn't been mentioned in the official betas yet, and I'm not sure if it will be resolved, even though it's listed as the release date for OpenCore version 1.0.7 this January.
