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

Please try the attached SSDT. Some notes:

• It's best to copy your working EFI folder to the EFI partition of a USB flash disk and add this SSDT to the USB flash disk. In case the boot process crashes, you can always boot from the normal EFI on the internal SSD.
• To boot the system with the new EFI, press the appropriate function key at the BIOS Splash Screen to open your BIOS Boot Menu, then select the USB flash disk.
• Also note that this method of disabling a GPU may no longer work under latest versions of Catalina and Big Sur.

It works. Thanks! So you used this path for construction of SSDT?

Just curious what is the logic?

Hi, guys! I just started buying parts to build my hackintosh again. So i bought the Z490 Vision G.

I want to ask about BIOS updates of the board .Does anyone know which version is stable, so that I can update to it.
To prevent any issues....with the build....?

Thanks.

Hey @CaseySJ

I have a question. It's not really urgent. So if you're busy, it doesn't need an answer right away.

So, at any rate, here is the question: on my Z490, I have a OWC TB 10Gb adapter plugged in to one of the two USB C TB ports. I have found that if I have anything else plugged in to either of the two TB ports or the USB ports that are tied into those two, I lose the OWC TB 10Gb adapter, and it does not initialize.

It would seem to me that I should be able to use the both of the USB C ports or the USB A ports above them or any combination of them with no effect back and forth, but that's not true. It seems if both are used, I may lose the other and vice versa.

Have you seen this issue with other users? Any thoughts?

I’ve had a similar issue. I believe it is to do with USBInjectAll. I created my own USB map keeping to the 15 port limit and that seemed to fix any issues I was having. This was only in Big Sur mind you, in Catalina, all ports were recognised, no matter what was plugged in.

Is there a way to set the default audio to load/boot on internal speakers ?

Every time the macOS boots up, it plays the chime through the headphones which is a good indication;
alcid = 28 in -> boot-args on the Z490 Vision D is working great as I have the green port on the back of the Vision D as set to internal. I got a front panel audio jack as set to headphones. For some reason it sets the default audio to play through headphones (Front Panel) not the green Rrear Back I\O.

...

Please try alcid=11 and then Audio Out 0 to 4.

@Higgie

In addition to reducing the number of USB ports to 15, did you also need to disabled XhciPortLimit?

Glad to hear it.

Just curious what is the logic?

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?

Hey there,

I have exactly the same problem. No idea how to solve it, and it doesn't really bother me that much, so I've just left it. Not much help, I'm afraid.

Although if you do find a solution, I'd love to know what it is...

Cheers,
V

@joe12south and @CamoViking I have this same problem and have posted a few times on this thread seeking assistance, but you guys are the first who chimed in with the same problem. I've ceased trying to fix it myself. Would love to say I've stopped caring, but who are we kidding...this kind of stuff (e.g. very nice user interface) is why I prefer Macs...

PortLimit patch is set to True in my configuration, as I configured my own SSDT with Hackintool, as opposed to a kext.
