What Works

Audio device: front panel, back panel

HDMI video output port (only tested in 1920x1080@30HZ with 4K monitor, didn't test the audio of HDMI)
DP video port, audio output of DP
Sleep
Wake up
iServices: iMessage, FaceTime, Apple ID, App Store, iCloud, Sidecar (with BCM94360CS2)
WiFI & Bluetooth
- Intel WiFi & bluetooth also works with patches: OpenIntelWireless/itlwm
- BCM94360CS2: WiFi works, bluetooth works, iServices works

What Broken

When the OS boot, the Apple logo first is big, then changes to smaller
In Hackintool -> USB, the name can't display correctly, displays ???

How To Enable Built Intel WiFi/Bluetooth Module

IMPORTANT: Please note that the KEXTs to enable Intel WiFi/bluetooth module maybe is not update to date, please visit OpenIntelWireless/itlwm to get the latest guideline, here only a simple steps before I tried to enable Intel WiFi/bluetooth module.

Download itlwm.kext from OpenIntelWireless/itlwm and place the kext file to EFI/OC/Kexts/
Downlaod IntelBluetoothInjector.kext from OpenIntelWireless/IntelBluetoothFirmware and place the kext file to EFI/OC/Kexts/
Copy IntelMausiEthernet.kext from Intel WiFi/Bluetooth Module KEXTS to directory EFI/OC/Kexts
Add itlwm.kext, IntelBluetoothInjector.kext, IntelMausiEthernet.kext to your config.plist, the section Kernel
Download HeliPort from here and install it
Reboot with reset NVRAM
Control the WiFi with HeliPort to on/off
Enjoy it

iGPU Patching

Purpose: I meet black screen issue of DP port when the long time sleep (for example, more than 30 mins), when wake up, the fan of CPU start to work, but the monitor no signal, so for fixing this issue, I patched the video ports of iGPU, after patched, the black issue was fixed.

Follow the official instruction: https://dortania.github.io/OpenCore-Install-Guide/extras/gpu-patches.html#igpu-busid-patching

Then add the patching information to DeviceProperties -> PciRoot(0x0)/Pci(0x2,0x0):

- framebuffer-con0-enable = 01000000							// HDMI port
- framebuffer-con1-enable = 00000000							// disabled it as this motherboard only two video output port
- framebuffer-con2-enable = 01000000							// DP port
- framebuffer-con0-alldata = 01050900 00080000 C7030000 		// data type: DATA
- framebuffer-con1-alldata = 02040A00 00040000 C7030000 		// data type: DATA
- framebuffer-con2-alldata = 03060800 00040000 C7030000 		// data type: DATA
- framebuffer-patch-enable = 01000000 							// data type: DATA

Notice

device-id is a must for DeviceProperties->PciRoot(0x0)/Pci(0x2,0x0), or you may suffer crashes on firefox, Photos etc.
Fill your SMBIOS information (can generate from GenSMBIOS) in PlatForm->Generic, else will can't boot.
