Yes, that is fine. I can now see the GFX0 and HDAU devices are correctly named, which is what I wanted to check. There are a few other devices that have missing sections of their IOReg Names, but these shouldn't affect the HDMI audio from the dGPU. It may mean these devices are not fully...

Can you post a screenshot of the PCIe tab with the IOReg Name fully expanded, so we can see the full name. Some of the devices show ‘pci-bridge’ in their IOReg Names, but we can’t see if the GPU or GPU Audio devices contain the same.

1. No the onboard WiFi will not work with macOS, as there are no drivers/kexts available for your Qualcomm WiFi card. You need to install a Broadcom or Intel WiFi/Bluetooth card, either as a direct replacement/swap for the Qualcomm card or use a spare x1 PCIe slot, with the companion Bluetooth...

Which OCLP variant/method are you using to enable the Broadcom WiFi and Realtek audio ? Is the RX 580 4G dGPU fully recognised by macOS, I.e. does the IOReg path contain any ‘pci-bridge’ entries when viewed in Hackintool > PCIe tab?

The first image with the Text list is normal, when the OpenCore Picker List is used. As it is only showing the Windows disk I can only assume you haven’t created the macOS installation USB correctly. I can’t read the text below the icons in the second screen image, so have no idea what options...

The Mediatek WiFi isn’t supported in macOS, so the builtin WiFi won’t work. This was the same for my ASUS B650E system. You need to use a Broadcom or Intel WiFi/BT card in macOS if you need WiFi & Bluetooth working. If you add either a Broadcom or Intel WiFi card you will need to disable the...

How are the three systems connected to the KVM, DisplayPort, HDMI or other display connector/cable? Which KVM switch are you using?

Have a look at @Shaneee GitHub repositories, there may be an El Capitan kernel you can use. https://github.com/Shaneee?tab=repositories

You would need to look in the ‘Zone’ setup/USB you downloaded to see which AMD kernels were available. With regards the ‘Still waiting for Root device’ error this is caused by the installer not activating the USB port you are using for the Yosemite installation device. You need to move the USB...

Which boot arguments are you using to help the installer boot?

Yosemite Zone if memory serves me right, contains a number of different Kernels, which can be called to be used by entering a specific boot argument, i.e. ‘AMD’ so the AMD Kernel is selected by the Distro. Have you tried using the AMD Kernel contained in the Distro? It may also contain a number...

If you have Above 4G Decoding = Enabled in your bios, you shouldn't be using either npci boot argument. You should only be using npci=0x3000 if you can't find and enable Above 4G Decoding in your bios. Remove the Boot Arg from your config.plist. I would recommend you switch SMBIOS from...

The OP is using Sequoia, so AppleHDA.kext is present and enabled in the OS. Also there are better/less expensive ways to fix builtin audio in Tahoe, than using the MaLad0n fix. Which I am not even sure will work correctly on an AMD Hack.

No it is not normal for Internal Speakers to disappear from the Sound Output options. If the audio codec is set with the correct layout ID then the Green coloured audio jack, which I assume your speakers are connected with, should work in any/every app. I would need to review your EFI folder...

Which version of AppleALC.kext are you using? Which Realtek Audio Codec does your Gigabyte motherboard use? Do you have any other entries in your OpenCore config.plist related to the Realtek audio codec, other than alcid=11? Web browsers on AMD Hack's can be a bit hit and miss. Have you tried...

Here is an OpenCore 1.0.7 EFI folder created for your Benico Mini PC. This EFI is based on the information I obtained from the various sites that have reviewed this mini PC. Your system may not be an exact match, but it should be close enough for you to boot to the Tahoe macOS installer. I am...

That's a laptop system, so not any use for your setup. Just because the laptop uses the same CPU/APU doesn't mean it will work in your Mini PC (Desktop) system. What would be more helpful is if you provided a copy of the system ACPI tables from your system. They can be obtained from Linux by...

I will have a look and see what I can do later, when I am next at my desk.

You need to provide some more information about your PC before anyone will be able to help you. Make and model of the motherboard, or prebuilt computer? Which graphics card are you using? Which SSD/NVME drive are you using? Which WiFi/BT card is installed?

You also need to make sure that the Serial Number (SMBIOS) you are using in your config.plist doesn’t belong to a real Mac.
