OpenCore EFI for Ryzen 5600G & MSI B450M PRO-VDH PLUS with a working iGPU and dGPU

EFI

Warning

Use at your own risk. I built this EFI for myself and it does not guarantee 100% work with your hardware.

MLB, ROM, Serial Number, SystemUUID sections are specifically left empty. Use GenSMBIOS to generate SMBios.

I recommend using an iMac20,1, if you are using an iGPU. Otherwise use these

📺 Build

Component	Model
CPU	AMD Ryzen 5 5600X @ 4.2GHz
Motherboard	MSI B450M PRO-VDH PLUS - BIOS Version 7A38v9E
GPU	ASUS AMD Radeon RX 580 DUAL OC*
RAM	ADATA XPG GAMMIX D20 2 x 8GB @ 3200 MHz
OS disk	Team Group GX2 256GB
Win disk	NVMe Apacer AS2280P4 256GB
Other disk	WD Blue 1 TB
macOS	Ventura 13.5 (22G74), Sonoma 14 beta 3 (23A5286i)
OpenCore	0.9.4 Release

Note
Instead of dGPU, you can use iGPU in the processor thanks to NootedRed, but then you will have problems with DRM, iServices and sleep.

🔧 BIOS

🔌 Settings

Component	Model
Fast boot	Disabled
SVM Mode	Enabled
Above 4G Decoding	Disabled
Resizable BAR	Disabled
Integrated Graphics Controller	Auto
IOMMU	Disabled
Initiate Graphic Adapter	Int Graphics (IGD)
UMA Frame buffer Size	Disabled*
XHCI Hand-off	Enabled
Boot Mode	CSM
Secure Boot and TPM	Disabled

Note

*If you use iGPU, set minimum 512 mb. There may be artifacts on some PCs/laptops if 512 MB of VRAM is set. To prevent this from happening, you need to set at least 1 GB of VRAM

⚠️ You can read more about the BIOS settings in the guide

🩼 Functional

• macOS thanks to dortania
• CPU by AMD-Vanilla
• Audio by AppleALC
• Ethernet by RealtekRTL8111
• dGPU by WhateverGreen
• iGPU by NootedRed
• iServices & DRM
• Sleep
• Airdrop / Handoff (there is no way to check)

Note

If you use iGPU: iServices will not work. There are small graphical artifacts when working with browsers on the Chromium engine. The developer of NootedRed is aware of the problem. A crutch is built into the config, which reduces the number of graphic artifacts

🪚 Change it for youself

Edit the core count patch to match your CPU

See AMD Vanilla OpenCore or OpenCore-Install-Guide

Mini-Guide

Find the three `algrey - Force cpuid_cores_per_package`

- `kernel -> Patch -> 0  -> Replace` for macOS 10.13.x, 10.14.x
- `kernel -> Patch -> 1  -> Replace` for macOS 10.15.x, 11.x
- `kernel -> Patch -> 2  -> Replace` for macOS 12.x, 13.0 to 13.2.1
- `kernel -> Patch -> 3  -> Replace` for macOS 13.3

```
B8000000 0000 => B8 <core count> 0000 0000
BA000000 0000 => BA <core count> 0000 0000
BA000000 0090 => BA <core count> 0000 0090
BA000000 00 => BA <core count> 0000 00
```

| CoreCount | Hexadecimal |
| --------- | ----------- |
| 6 Core    | 06          |
| 8 Core    | 08          |
| 12 Core   | 0C          |
| 16 Core   | 10          |
| 32 Core   | 20          |
| 64 Core   | 40          |

For example 5600G has 6 cores

```
B8 06 00000000
BA 06 00000000
BA 06 00000090
BA 06 000000
```

🧱 Scripts

Warning

All scripts must be used with elevated rights! To do this, use sudo bash <name_script>.sh

1. hostname.sh - change the name of your computer's name or local hostname on Mac
2. clear-network-interfaces.sh - helps to solve problems with en0 ethernet

💡 Tips

1. If you want to change the processor name, use this
2. If you have a 1-in-1 CPU and motherboard configuration like mine, you can use this config. If it is different, I advise you to assemble it yourself according to the guide. This way you will spend less time solving problems and everything will work fine. 🫡
