Intel Wi-Fi/Bluetooth Support

To enable Intel Wi-Fi and Bluetooth on macOS, you need to install the appropriate kexts. The recommended kexts for this are:

• itlwm.kext (or airportitlwm.kext) for Intel Wi-Fi:
  GitHub - itlwm

• HeliPort: A macOS menu bar app to manage Intel Wi-Fi connections:
  GitHub - HeliPort

System Functionality & Known Issues

Working Features:

• Everything works as expected except for Apple Airport Card functionalities and S4 (Hibernate) sleep.

To Enable Full Functionality:

• You can swap your Intel Wi-Fi/Bluetooth card with a natively supported one (such as the BCM94360 or BCM94350), and use patches from OpenCore Legacy Patcher (OCLP) to ensure full support for Apple features.

Known Bugs:

• A2 Error (Boot device undetected): This occurs during POST because ASRock motherboards sometimes fail to detect the EFI partition, even on Windows or Linux.
• Intel Wi-Fi/Bluetooth: These devices are not officially supported by macOS and may experience lag or instability.
• Internal USB LED Controller (Port 11): The internal USB LED controller is disabled due to erratic behavior during shutdown and reboot. The LED controller cannot be turned off via the S5 call from macOS.

SMBIOS Configuration

This EFI uses the MacPro 7,1 SMBIOS, which is recommended for optimal compatibility with modern AMD Ryzen CPUs.

Creating Your Own SMBIOS:

To create or modify your own MacPro 7,1 SMBIOS, use GenSMBIOS:

• GenSMBIOS GitHub Repository

BIOS Settings for ASRock A520M-ITX/AC

To ensure compatibility with macOS, adjust the following BIOS settings:

Enable:

• Resizable BAR Support
• Above 4G Decoding

Disable:

• CSM Support (Compatibility Support Module)

Multi-Booting with Windows (Optional)

Disabling ACPI injections:

If you're dual-booting Windows and macOS on your Ryzen system, it's recommended to disable ACPI injections to avoid BSODs and other issues in Windows.

Use the OpenCore_NO_ACPI_Build to prevent ACPI-related conflicts.

Steps:

1. Download the OpenCore_NO_ACPI_Build version that matches your current OpenCore version:
   OpenCore_NO_ACPI_Build Releases
2. Extract the files and replace the following in your EFI folder:
   • BootX64.efi (in EFI/Boot)
   • OpenCore.efi (in EFI/OC)
   • Any Drivers and Tools you use in the respective folders (EFI/OC/Drivers, EFI/OC/Tools)
3. Modify the config.plist:
   • Under ACPI/Quirks, add:
     EnableForAll (Type: Boolean) → False
   • Under Booter/Quirks, add:
     EnableForAll (Type: Boolean) → False

This will ensure that ACPI modifications don't affect other operating systems.
