Opencore EFI for A520m-itx/ac ryzen cpu and NAVI GPU

You need to manually download and install itlwm.kext (or airportitlwm.kext) to use WIFI

itlwm / Airportitlwm : https://github.com/OpenIntelWireless/itlwm

Heliport : https://github.com/OpenIntelWireless/HeliPort

Every function works except Apple airportcard required ones ,such as sidecar and airdrop.

You may swap your wifi card into natively supported devices BCM94360 or BCM94350 with OCLP patcher to work these functions properly. My recommandation is wireless modules from "Fenvi"

• Random blackscreen during POST.
• A2 Error (Boot device undetected) during POST.
• Since intel Wi-Fi/Bluetooth are not officially supported in MacOS, it might be laggy.

ASRock motherboards are not good for hackintoshing, change your motherboard into different manufactures such as ASUS,GIGABYTE may resolve A2 Boot errors. (Seems ASRock motherboards sometimes cannot recongnize Bootstrap related efi partitions)

If you experience blackscreen/unresponsiveness before OC picker, you may try manual boot config with efibootmgr : https://www.reddit.com/r/hackintosh/comments/fj3zrj/booting_opencore_without_the_usb_on_an_asrock/

This hackintosh EFI uses MacPro 7,1 SMBIOS.

Create your own MacPro 7,1 SMBIOS with GenSMBIOS

• Read the Dortania guide for creating your USB from Windows or macOS
• Guide Dortania - USB creation
• Download EFI and copy it to your USB drive.

Since photoshop 25, no additional adobe patch is required.

Ryzentosh requires a lot of SSDT / Patch / Quirks modifications, which are the main reasons of BSOD in Windows.

If you are using Ryzentosh and Windows, I recommand to use NO_ACPI_Build version of OC.

Download the correct OpenCore_NO_ACPI_Build that matches your OpenCore version and unzip it

https://github.com/wjz304/OpenCore_NO_ACPI_Build/releases

Replace the following files in your EFI Folder:

BootX64.efi (in EFI/Boot)
OpenCore.efi (in EFI/OC)
Any Drivers you use (in EFI/OC/Drivers)
Any Tools you use (in EFI/OC/Tools)

Add the following Keys to your config.plist:

Under ACPI/Quirks, add: EnableForAll (Type: Boolean) and set it to False
Under Booter/Quirks, add: EnableForAll (Type: Boolean) and set it to False
