Hardware
  • Motherboard: Gigabyte Z390 Aorus Elite
  • CPU:Intel i7 9700
  • iGPU:Intel UHD Graphics 630
  • dGPU:AMD Radeon RX 6600 8GB
  • Sound:Realtek ALC1220
  • Ethernet:Intel I219V7
  • Wifi + BT:Fenvi FV-T919 BCM94360CD.
What works well?
  • Radeon graphics card (VDA decoder fully supported)
  • Shutdown, restart and sleep
  • Audio (ALC1220 and HDMI)
  • USB ports (USB ports map for this motherboard)
  • Airdrop, iMessage...
BIOS settings (version F10h)

  • CFG Lock: Disabled
  • CSM: Disabled
  • VT-d: Disabled
  • Fast Boot: Disabled
  • OS Type: Windows 8/10 WHQL
  • Platform Power Management: Disabled
  • XHCI Hand-Off: Enabled
  • Network Stack: Disabled
  • Wake on LAN: Disabled
  • Secure Boot: Disabled
  • DVMT Pre-Allocated: 256M or higher
  • Integrated Graphics: Disabled / Enabled (according to SMBIOS)

OpenCore 0.8.6

For the installation to be successful, 3 parameters related to security must be set:
  • SecureBootModel=j160 or SecureBootModel=Default in config.plist (Apple secure boot j160 corresponds to MacPro7,1 and Default sets the same model as in SMBIOS)
  • SIP enabled (csr-active-config=00000000 in config.plist)
  • Gatekeeper enabled (sudo spctl --master-enable in Terminal).
These security options can be changed after installation as they do not are required for Monterey / Ventura to run.

SMBIOS

SMBIOS model that works best on my systems is iMac19,1. This Mac model requires:
  • AMD dGPU as main card
  • Intel 630 iGPU enabled in BIOS
  • iGPU code for headless mode in config.plist.
iMacPro1,1 or MacPro7,1 SMBIOS can be set if desired. They work also very well. These Mac models require:
  • AMD dGPU as main card
  • Intel 630 iGPU disabled in BIOS (as this Mac models lack integrated GPU, they have only AMD GPU)
  • RestrictEvents.kext to avoid RAM misconfiguration warnings (MacPro only)
  • CPUFriend.kext: not mandatory but in my opinion it improves CPU Power Management (MacPro only).
CPUFriend.kext

Although the CPU is well detected with MacPro's SMBIOS, my guess is that it does not run at low frequency as often as it does with iMac19.1. For this reason, I have generated a CPUFriendDataProvider.kext extension from the CPUFriendFriend command to accompany CPUFriend.kext. With these 2 kexts (CPUFriendDataProvider.kext + CPUFriend.kext) the CPU shows correct power management and frequency drops to 800 MHz at system idle.

SSDTs, drivers and tools

SSDTs
  • SSDT-AWAC-DISABLE: to fix errors with system clock on Z390, B460, Z490 motherboards
  • SSDT-EC-USBX: fake Embedded Controller on Skylake and later, also fix USB power
  • SSDT-PLUG: power management on Haswell and newer CPUs; to configure the plugin-type=1 parameter on the first processor
  • SSDT-PMC: native NVRAM support on systems that lack it, for example Z390 chipsets
  • SSDT-USBW: to wake from sleep with a single mouse or keyboard touch (this SSDT works with USBWakeFixup.kext) >> very likely not needed if USB device in DeviceProperties has acpi-wake-type=01.
Drivers
  • HfsPlus.efi: to recognize HFS+ devices
  • OpenRuntime.efi: essential driver to run macOS
  • OpenCanopy.efi: graphical picker with themes
  • CrScreenshotDxe.efi: Screenshots in OpenCore.
Tools
  • OpenShell.efi: UEFI shell to perform command line tasks from OpenCore
config.plist

Some settings:
  • DeviceProperties >> Add >> PciRoot(0x0)/Pci(0x14,0x0): acpi-wake-type as data=01, to improve wake from sleep
  • Misc >> Boot >> PickerAttributes=144 to enable Flavours system
  • NVRAM> 7C436110-AB2A-4BBB-A880-FE41995C9F82> boot-args: alcid=7 agdpmod=pikera (agdpmod=pikera not needed with RX 580, only with RX 6600 and other Navi cards)
  • Misc >> Security >> AllowToggleSip=True to show in the picker the ToggleSIP tool that allows to easily switch between SIP enabled and SIP disabled for the current boot.
Intel UHD 630 headless mode
  • iGPU and dGPU must be enabled in BIOS with dGPU as primary
  • There should be no cable between iGPU HDMI port and any type of display
  • Lilu and WhatEverGreen properly installed
  • SMBIOS iMac19.1.
You have to add in DeviceProperties >> Add:
XML:
<key>PciRoot(0x0)/Pci(0x2,0x0)</key>
<dict>
    <key>AAPL,ig-platform-id</key>
    <data>AwCRPg==</data>
    <key>device-id</key>
    <data>mz4AAA==</data>
    <key>enable-metal</key>
    <data>AQAAAA==</data>
    <key>rps-control</key>
    <data>AQAAAA==</data>
</dict>

This code has data values in Base64, in plist editors they can be seen as hexadecimal, e.g. AwCRPg== in Base64 (AAPL,ig-platform-id) = 0300913E in hexadecimal.

To check if the VDA Decoder function is activated you can get Hackintool app (Fully Supported or Failed in the first System tab).

Notes:
  • AAPL,ig-platform-id=07009B3E is mandatory
  • device-id=9B3E000 to be displayed as Intel UHD Graphics 630 instead of Kabylake Unknown
  • enable-metal=01 to enable Metal 3 in Ventura
  • rps-control=01 to enable RPS control patch (improves IGPU performance).
Intel UHD 630 as single GPU

If you don't have an external graphics card and need to use the iGPU as single card, you have to use iMac19,1 SMBIOS with code in config.plist to patch the framebuffer and other properties so that the iGPU is well detected:
XML:
<key>PciRoot(0x0)/Pci(0x2,0x0)</key>

AMD RX 6600 on Ventura with MacPro or iMacPro SMBIOS

AMD Navi cards run fine on Ventura when using iMac SMBIOS with agdpmod=pikera in boot args as the only needed setting. But when using MacPro or iMacPro SMBIOS a lot of users have reported black screen. The simplest way to fix this is to add in DeviceProperties of config.plist some properties that set Henbury framebuffer for each of the 4 ports of this GPU.

By default, Radeon framebuffer (ATY,Radeon) is loaded. But, in AMDRadeonX6000Framebuffer.kext >> Contents >> Info.plist we can see that AMDRadeonNavi23Controller has ATY,Henbury and 6600 series are Navi 23. This is why this framebuffer is selected.

The patch is added in this way:
XML:
<key>DeviceProperties</key>
    <dict>
        <key>Add</key>
        <dict>
            <key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key>
            <dict>
                <key>@0,name</key>
                <string>ATY,Henbury</string>
                <key>@1,name</key>
                <string>ATY,Henbury</string>
                <key>@2,name</key>
                <string>ATY,Henbury</string>
                <key>@3,name</key>
                <string>ATY,Henbury</string>
            </dict>
        </dict>
        <key>Delete</key>
        <dict/>
    </dict>

Notes:
  • PCI path to the GPU may be the same on your system but it is convenient to check it with Hackintool (app) or gfxutil (Terminal utility).
  • This is not needed for Monterey.
  • This is not needed for RX 580 or any other Polaris card.
If needed for other Navi cards, the framebuffers to be loaded are different for each family:
  • 5500 ATY,Python
  • 5700 ATY,Adder
  • 6600 ATY,Henbury
  • 6800 ATY,Belknap
  • 6900 ATY,Carswell
Installing Big Sur or Monterey or Ventura

The process is almost the same for installation and for update:
  • You need a working EFI folder
  • Download macOS from Software Update or create USB installer; I don't comment about creating USB installer because there are a lot of sites with this info
  • Run Install macOS Monterey / Ventura app or the setup program from the booted USB
  • The process has 2 reboots booting from Install macOS disk and a third reboot booting from the target disk.
SMBIOS and config.plist files

There are eight configuration files, the ones starting with config-12 are for Monterey and the ones starting with config-13 are for Ventura. Variants are included for 4 possible SMBIOS:
  • iMac19,1 with AMD dGPU + iGPU headless mode
  • iMac19,1 with iGPU as main card without dGPU
  • MacPro7,1 with dGPU + iGPU disabled
  • iMacPro1,1 with dGPU + iGPU disabled.
List of config.plist files:
  • config-12-imac-amd.plist: iMac19,1 + dGPU AMD + iGPU enabled in BIOS
  • config-12-imac-intel.plist: iMac19,1 + iGPU enabled in BIOS as main card
  • config-12-imacpro.plist: iMacPro1,1 + dGPU AMD + iGPU disabled in BIOS
  • config-12-macpro.plist: MacPro7,1 + dGPU AMD + iGPU disabled in BIOS
  • config-13-imac-amd.plist: iMac19,1 + dGPU AMD + iGPU enabled in BIOS
  • config-13-imac-intel.plist: iMac19,1 + iGPU enabled in BIOS as main card
  • config-13-imacpro.plist: iMacPro1,1 + dGPU AMD + iGPU disabled in BIOS
  • config-13-macpro.plist: MacPro7,1 + dGPU AMD + iGPU disabled in BIOS.
Notes
  • rename selected config file to config.plist
  • current GPU is AMD RX 6600 XT; for RX 580 and other Polaris cards remove agdpmod=pikera from boot-args and don't use the framebuffer patch
  • add serial numbers for the SMBIOS model.
Important!
  • Don't forget to rename the selected config file to config.plist.
  • Do ResetNVRAM the first time you boot a new EFI.
  • Press spacebar to show auxiliary entries in the picker.

@Feartech
My bad :) copy paste has drawbacks sometimes.
 
@Feartech
I have made the post in the sub-forum Ventura Desktop Support but really I wanted to do it in Ventura Desktop Guides, can you please move the thread? Thanks.

Alternative method to Henbury patch to avoid black screen with MacPro or iMacPro SMBIOS on Ventura with Navi 23 GPU (thanks Dreamwhite)

Using SSDT-BRG0.aml fixes black screen on Ventura with SMBIOS models lacking iGPU. This SSDT allows to define a missing pci-bridge device. With it, the Henbury patch is no longer necessary.

Do not forget that the Henbury patch clearly drops down the GeekBench 5 scores, however with SSDT-BRG0 scores are as expected, in line with those got by many users with this graphics card.

SSDT-BRG0:
C-like:
/*
 * This table provides an example of creating a missing ACPI device
 * to ensure early DeviceProperty application. In this example
 * a GPU device is created for a platform having an extra PCI
 * bridge in the path - PCI0.PEG0.PEGP.BRG0.GFX0:
 * PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)
 * Such tables are particularly relevant for macOS 11.0 and newer.
 */
 
DefinitionBlock ("", "SSDT", 2, "ACDT", "BRG0", 0x00000000)
{
    External (_SB_.PCI0.PEG0.PEGP, DeviceObj)

    Scope (\_SB.PCI0.PEG0.PEGP)
    {
        Device (BRG0)
        {
            Name (_ADR, Zero)  // _ADR: Address
            Device (GFX0)
            {
                Name (_ADR, Zero)  // _ADR: Address
            }

            Device (HDAU)
            {
                Name (_ADR, One)  // _ADR: Address
            }
        }
    }
}
Be sure of the PCI path to your dGPU, mine is /PCI0@0/PEG0@1/PEGP@0/GFX0@0 so the SSDT has these lines:
Code:
External (_SB_.PCI0.PEG0.PEGP, DeviceObj)
Scope (\_SB.PCI0.PEG0.PEGP)
Modify the SSDT (if needed) to be set within your system. How to chek the PCI path?
  • gfxutil utility in Terminal, look for the line containing GFX0 at the end
  • Hackintool >> PCIe tab >> pointer over Navi 23 line >> copy IOReg patch.

SMBIOS model that works best on my systems is iMac19,1. This Mac model requires:
  • AMD dGPU as main card
  • Intel 630 iGPU enabled in BIOS
  • iGPU code for headless mode in config.plist.
MacPro7,1 SMBIOS can be set if desired. It works also very well. This Mac model requires:
  • AMD dGPU as main card
  • Intel 630 iGPU disabled in BIOS (as this Mac models lack integrated GPU, they have only AMD GPU)

Notes:
  • PCI path to the GPU may be the same on your system but it is convenient to check it with Hackintool (app) or gfxutil (Terminal utility).
  • This is not needed for Monterey.
  • This is not needed for RX 580 or any other Polaris card.
If needed for other Navi cards, the framebuffers to be loaded are different for each family:
  • 5500 ATY,Python
  • 5700 ATY,Adder
  • 6600 ATY,Henbury
  • 6800 ATY,Belknap
  • 6900 ATY,Carswell
Installing Big Sur or Monterey or Ventura

The process is almost the same for installation and for update:
  • You need a working EFI folder
  • Download macOS from Software Update or create USB installer; I don't comment about creating USB installer because there are a lot of sites with this info
  • Run Install macOS Monterey / Ventura app or the setup program from the booted USB
  • The process has 2 reboots booting from Install macOS disk and a third reboot booting from the target disk.
SMBIOS and config.plist files

There are eight configuration files, the ones starting with config-12 are for Monterey and the ones starting with config-13 are for Ventura. Variants are included for 4 possible SMBIOS:
  • iMac19,1 with AMD dGPU + iGPU headless mode
  • iMac19,1 with iGPU as main card without dGPU
  • MacPro7,1 with dGPU + iGPU disabled
  • iMacPro1,1 with dGPU + iGPU disabled.
List of config.plist files:
  • config-12-imac-amd.plist: iMac19,1 + dGPU AMD + iGPU enabled in BIOS
  • config-12-imac-intel.plist: iMac19,1 + iGPU enabled in BIOS as main card
  • config-12-imacpro.plist: iMacPro1,1 + dGPU AMD + iGPU disabled in BIOS
  • config-12-macpro.plist: MacPro7,1 + dGPU AMD + iGPU disabled in BIOS
  • config-13-imac-amd.plist: iMac19,1 + dGPU AMD + iGPU enabled in BIOS
  • config-13-imac-intel.plist: iMac19,1 + iGPU enabled in BIOS as main card
  • config-13-imacpro.plist: iMacPro1,1 + dGPU AMD + iGPU disabled in BIOS
  • config-13-macpro.plist: MacPro7,1 + dGPU AMD + iGPU disabled in BIOS.
Notes
  • rename selected config file to config.plist
  • current GPU is AMD RX 6600 XT; for RX 580 and other Polaris cards remove agdpmod=pikera from boot-args and don't use the framebuffer patch
  • add serial numbers for the SMBIOS model.
Important!
  • Don't forget to rename the selected config file to config.plist.
  • Do ResetNVRAM the first time you boot a new EFI.
  • Press spacebar to show auxiliary entries in the picker.

Do you know if this GUIDE would work on "gigabyte-z390-aorus-master"? thanks in advance!

For the most of settings, I think so. You don’t need agdpmod=pikera in boot args either Henbury patch if using Ventura with MacPro or iMacPro SMBIOS.
Main difference between our mobos is the Intel wifi and BT, keep the kexts and settings in config.plist needed for it.
 
Alternative method to Henbury patch to avoid black screen with MacPro or iMacPro SMBIOS on Ventura (2)

There are some more advanced SSDT configurations such as SSDT-VEGA.aml which, in addition to creating devices, does so by mimicking the way real Macs are configured (EGP0 and EGP1 devices instead of BRG0).

SSDT-VEGA has the same benefits as SSDT-BRG0: Henbury patch not needed and good GeekBench 5 scores.

It also requires checking the PCI path to your graphics card. In the example code I keep the same path as in the previous SSDT-BRG0.

C-like:
DefinitionBlock ("", "SSDT", 2, "HACK", "VEGA", 0x00000000)
{
    External (_SB_.PCI0, DeviceObj)
    External (_SB_.PCI0.PEG0, DeviceObj)
    External (_SB_.PCI0.PEG0.PEGP, DeviceObj)

    Scope (\_SB)
    {
        Scope (PCI0)
        {
            Scope (PEG0)
            {
                Scope (PEGP)
                {
                    Method (_STA, 0, NotSerialized)  // _STA: Status
                    {
                        If (_OSI ("Darwin"))
                        {
                            Return (Zero)
                        }
                        Else
                        {
                            Return (0x0F)
                        }
                    }
                }

                {

                    Method (_STA, 0, NotSerialized)  // _STA: Status
                    {

                        }
                        Else
                        {
                            Return (Zero)
                        }
                    }

                    Device (EGP1)
                    {
                        Name (_ADR, Zero)  // _ADR: Address
                        Device (GFX0)
                        {
                            Name (_ADR, Zero)  // _ADR: Address
                        }

                        Device (HDAU)
                        {
                            Name (_ADR, One)  // _ADR: Address
                        }
                    }
                }
            }
        }
    }
