1. Warning

⚠️Warning A⚠️： Before using the EFI, you should at least understand how do you install macOS and understand the file structure of OpenCore.

If you don't, I strongly recommend you to read the OpenCore Install Guide before using this EFI.

Directly using this EFI does not mean your system can boot normally, even though the configuration is identical, you would need these knowledge to solve problems in your case.

📖 OpenCore Install Guide

⚠️Warning B⚠️： This EFI is based on OpenCore, if you currently are using Clover, please read following document to avoid unpredictable error.

📖 Converting from Clover to OpenCore Guide

⚠️Warning C⚠️：This EFI does not contain any platform information (SN, UUID etc.). You can generate these information by using OpenCore Configurator.

4. Getting Ready

4.1. Wi-Fi & Bluetooth module replacement

The motherboard comes with Intel® Wireless-AC 9560 module, support 802.11ac and Bluetooth 5.0 with 2x2 802.11ac 2.4/5Ghz Wi-Fi. We need to remove this module and replace it with BCM94360CS2 module,BCM94360CS2 module required an NGFF to M.2 adapter. Steps shown below（By icyleaf）：

In Windows 10 you might need to install drivers manually in order to use Wi-Fi and Bluetooth.

4.2. Flashing Special BIOS to enable TB 3

Download Z39PGIX4.40C, store in a thumb drive and flash the BIOS by executing Instant Flash. Steps of how to flash BIOS can be found on Asrock Official site 📖ASRock BIOS Upgrade Instruction.

This is for enabling Thunderbolt 3 on MacOS.（Do I have to flash this BIOS? I tried and no good with TB 3 while using BIOS 4.40😂.） If you do not use Thunderbolt 3 port, you can skip this step. You can flash back to 4.40 anytime you want.

- ⚠️Warning：There are risks while flashing BIOS,
- ⚠️This instruction dose not responsible for any hardware damage.

You also need to check your rp21's reg value to choose the proper SSDT file by using IORegistryExplorer.

Download IORegistryExplorer , search for rp21 and check the value under reg.

If it includes dc, you don't need to do anything. However if it includes d8 then you need to download the SSDT-TbtOnPch_PINI_D8.aml file under Tools, then put it under OC -> ACPI and remove SSDT-TbtOnPch_PINI.aml. You need to made modification to your config file as well.

4.3. BIOS Setting (4.40c)

- With iGPU

• Advanced

  • Chipset Configuration

    • Vt-d → Disable
    • Share Memory → 128MB
    • IGPU Multi-Monitor → Enable

  • Super IO Configuration

    • Serial Port → Disable

  • USB Configuration

    • XHCI Hand-off → Enable

  • Intel (R) Thunderbolt

    • Thunderbolt (TM) Support → Enable
    • Thunderbolt Usb Support → Enable
    • GPIO3 Force Pwr → Enable

4.4. SMBIOS

• Step 1：
  • Use the latest OpenCore Configuratortor open config.plist.

• Step 2：
  • Choose PlatformInfo then choose on the top DataHub - Generic — PlatfromNVRAM, click the "up and down arrow" button on the right side on the Check Coverage button located at the bottom of the interface.

• Step 3：
  • Choose model iMac19,1 if your CPU comes with iGPU, otherwise choose Mac Pro7,1.

4.5. Clean up emulated NVRAM（Optional）

If you used emulated NVRAM before, you need to clean up the emulated NVRAM to get the native NVRAM works. If you never used emulated NVRAM or you are doing a fresh install, you can skip this part.

4.5.1. Clean up LogoutHook

• Step 1：

  Execute in terminal

  sudo defaults read com.apple.loginwindow LogoutHook

  If the output is

  The domain/default pair of (com.apple.loginwindow, LogoutHook) does     not exist

  Means no LogoutHook left.

• Step 2：

  Remove LogoutHook.command file,execute in terminal

  sudo rm -rf $(sudo defaults read com.apple.loginwindow LogoutHook)

• Step 3：

  Clean up LogoutHook trigger setting, execute in terminal

  sudo defaults delete com.apple.loginwindow LogoutHook

4.5.2. Remove Files（If there are any）

• nvram.plist in EFI prartition.
• VariableRuntimeDxe.efi and EmuVariableRuntimeDxe.efi in /EFI/OC/Drivers

4.5.3. Examination NVRAM function

• Execute in terminal each line at a time,

  sudo -s

  sudo nvram -c

  sudo nvram myvar=test

  exit

• Reboot your device, then execute in terminal

  vram -p | grep -i myvar

• If myvar test is included in your return line, then the NVRAM is working properly.

4.6. Mapping USB（Recommanded）

• Downlaod Hackintool
• Launch Hackintool then choose USB

• Select the ports you don't need then click - to delete them.
• The number of ports（SSP1 is not included）should below 15, you need to choose the type of device for them as well（USB2，USB3，TypeC+SW，TypeC and Internal）
• ⚠️ Noticed：HS14 should be set as Internal

• Port distribution shown as below（HS stands for USB2 and SS stands for USB3）

• Export the kext file, which usually would save to your desktop as USBPort.kext, put it in EFI -> OC -> Kext.
• Reboot your system.

4.7. Sensors

The latest release of this EIF is using the FakeSMC by CloverHackyColor which supports AMD's RX5000 Series and RX6000 Series GPU Die temperature sensor.

5. More

5.1. Big Sur Style Icons

There are many applications are not optimized for Big Sur with the new icon style, we can replace these icons for a unify UI. Image below is how the lunchpad looks like in my case ：

You can download these icons form macosicons. I personally also make some of the icons and uploaded them to this website (this is an open-sourced project). If you are capable to make icons for the application you are using, please feel free to make contribution to this project.

6. Known Issues

• The enable of the patch change _E2C to XE2C will cause APIC Error while booting Windows with OC

  Solution: disable the TB3 Function or boot Windows with BIOS interface.

• My device dose not support Apple TV + ?

  Solution: Run

  defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes
  

  forces AMD DRM decoder for streaming services (like Apple TV and iTunes movie streaming)
  

• Time do not sync between Windows 10 and macOS.

  • Solution：In Windows 10, run following code in CMD
    

    Reg add HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation /v RealTimeIsUniversal /t REG_DWORD /d 1
