EFI-RYZEN-B550-RX6600

ℹ️ The current version is fully macOS Monterey and Ventura compatible. OpenCore, drivers, and kexts are always up to date!


OpenCore macOS

⚠️ DISCLAIMER: THIS IS NOT A GUIDE!
It's just my complete EFI for my hardware based on my experiments, please refer to Dortania before doing anything. I am not responsible for any damage. This OpenCore configuration is optimized for my specific hardware, so please use it only as a reference or if you happen to have the same or similar hardware.

💻 Hardware:

Category Component
CPU 3,5 GHz AMD Ryzen 5 5600 6-Core Processor
GPU ASROCK Challenger - AMD Radeon RX 6600 8 GB Challenger 8GB
RAM 16GB GLOWAY DDR4 3200MHZ (XMP)
CHIPSET B550M DS3H Gigabyte
SSD 120GB ADATA SATA
Wi-Fi/BT Fenvi FV-HB1200
Ethernet Realtek RTL8111
Audio Realtek ALC897 (layout-id=12)

✅ Working:

  • CPU power management.
  • Graphics acceleration.
  • Keyboard & Mouse
  • Wi-Fi.
  • Bluetooth.
  • USB ports.
  • HDMI video & audio output.
  • Ethernet.
  • Audio (Internal speakers, 3.5mm headphone jack).
  • Internal microphone.

❌ Not working:

Wi-fi, Bluetooth and AirDrop are not working since i don't have yet a native Wi-fi card and my motherboard doesn't have one. Currently using with wired network on my ethernet port

All features are working, just added a Fenvi FV-HB1200 board. Now we have Wi-Fi, Bluetooth (usb mapped), AirDrop and others.

🔐 SMBIOS

You will need to generate your own SMBIOS and configure, since is required to fully work with macOS. As per this guide you can use the following SMBIOS: iMacPro1,1 or MacPro7,1. Note that if your hardware is different for the one mentioned here you have tho choose an appropriate SMBIOS, more details in the guide.

Use GenSMBIOS to generate your own unique SMBIOS and then copy each parametter following path (recomended to follow the guide above):

  • Config.plist -> PlatformInfo -> Generic

BIOS setup:

IMPORTANT: Need to enable Above 4G Decoding and set Resize BAR to Auto on BIOS or will not work! If you don't have this on your BIOS you will need to adjust the config.plist, refer to AMD bios settings and boot-args

Currently i'm running the F18 BIOS version and works great
