Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

@CaseySJ,

The previous versions of the SSDT to hide a GPU in my system has always made my system fail to boot, but seeing your post above explaining the process made me curious to see whether I could create one for my needs. The card in question is an RX6800 in slot 1. Here is my IOReg output, and my attempt at modifying your SSDT (I haven't tried it yet - Just wanted to make sure I understand the process!). Can you confirm whether I've got the right idea?
Yes, you have it right! Please let us know whether it works.

@emistral would be interested in this as well.
 
Hey, Casey! Thank you so much for your effort for the EFI. I just made a fresh boot of your OC 0.6.7, and I was wondering if it’s normal that SideCcar and screen mirroring are not working? Also, I can’t find the sound output of my monitor. Sometimes, when I turned off my monitor and turned back on, then I can see my monitor sound output. Can you show me what is wrong? I use the iMac 20, 2. My PC setting:
i9-10850K
Vision D Z490
Fenvi T919
Intel UHD 630
Kraken Z73
Corsair RGB Vengeance 32GB 3200MHz 2x16GB
EVGA 1000 watt power supply.
Thanks again!
Hello @Hackintosh-ProVirgin,

Glad to hear the build went well. Unfortunately both Sidecar and screen mirroring aren't working at this time. We've had sporadic luck with these features so I wouldn't give up on them; instead I would just wait and see if a solution is found. Screen mirroring does work with system name iMacPro1,1.

As for sound output to monitor, please try a DisplayPort cable (such as this one) if you're currently using HDMI. The USB-C side of the cable can be connected to either of the two Thunderbolt ports.

Works a treat. System Information > Graphics/Displays now only shows the RX580.

@Hackintosh-ProVirgin, Hi!

I'm building also a hackintosh in this weekend. I want to ask you about "Kraken Z53".
How does it work under hackintosh? Does sleep work? Do you have any issues or something because I want to buy the Kraken Z53.

Thanks in advance.

I used Casey’s 0.6.7 oc efi, so far only sidecar, Apple TV, screen mirroring, and hdmi sound, but sleep and hot plugging are working on tb3. I used iMac 20,2 and intel igpu since 5700xt is literally $1000 now!
 
Glad to hear it.


The thinking was as follows:
  • Your Nvidia GPU was being attached to:
    • _SB.PCI0.IOU1.PXS2.PCI-BRIDGE@4.GFX1
  • There are several PCI bridges on PXS2, but your GPU is attached to the bridge on Address 4, hence PCI-BRIDGE@4.
  • The DSDT and SSDT files confirm that the firmware (BIOS) is not defining any default devices under PXS2, which means we are free to define our own.
  • We start by creating a device at the "PCI-BRIDGE@4" location, which is done as shown below. Your GPU is connected to this particular bridge.
    • Note that we set _ADR to 0x00040000. This ensures that our new PBR4 device is registered to the correct PCI bridge.

  • Then we define the actual GPU device as a sub-device of PBR4, as follows:

  • And finally we can create a Device Specific Method (_DSM) for GFX1 that will hide the GPU from macOS. Notice that the _DSM method is created for _SB.PCI0.IOU1.PXS2.PBR4.GFX1, where the last two elements of this path had to be created first.

By the way, are you running Mojave, Catalina, or Big Sur?
I am running all of those +HS. I tried injecting the SSDT with:

through refind without OC, but it did not work. Thanks for the explanation.
 
Hi, all! I have problem. I have updated my Z490D to OpenCore 067, and, when my BIOS is booting, I see this screen. My BIOS is f6.

It means you need to compare your config.plist with the sample.plist from OpenCore when you update OpenCore.

How can I do this I just upload to
My hard disk the 067vision d files WiFi from the thread
