To help me tailor the exact XML code or patch values for your system, could you tell me: What is your specific ?
In your config.plist under DeviceProperties , you may need to change the connector type of the port mapped to HDMI. Standard HDMI hex value is 00080000 .
macOS hides HDMI audio outputs unless the GPU sends a specific EDID (Extended Display Identification Data) handshake.
You'll see something like:
Running 4K displays at 60Hz over HDMI is a common goal for Hackintosh builders, but it requires specific patches.
Copy this into your config, reboot, and your HDMI will be physically remapped.
Standard HDMI patches sometimes limit 4K displays to a sluggish 30Hz refresh rate due to pixel clock limitations. hackintosh hdmi fix
Check your for AppleALC.kext . Common IDs for HDMI audio pass-through include 1 , 3 , or 11 , but this varies by codec.
Once you have the right Platform ID, the real work begins.
Next, locate your audio controller path in DeviceProperties (usually PciRoot(0x0)/Pci(0x1f,0x3) ). Add the matching key there as well: (String): onboard-1 To help me tailor the exact XML code
If patching doesn't work immediately, try adding these in your NVRAM section: -cdfon : Enables HDMI 2.0 (4K @ 60Hz) support.
HDMI audio relies on the AppleALC.kext driver. This kext needs a to match your motherboard's audio chip.
hda-gfx = "onboard-1"
This tells macOS that the audio controller and the graphics card are linked for digital audio pass-through. Step 2: Adjust AppleALC Layout IDs
