Troubleshooting OpenCore Boot Error for Ryzen and RX 6700 XT Setup

SOLUTIONS:

Target Audience: Intermediate to Advanced Hackintosh Users

Objective:

Address the boot error encountered while installing macOS Ventura on a system with Ryzen 5 5600G, RX 6700 XT, and Gigabyte B550M.

Troubleshooting Steps:

1. Check OpenCore Version:

   • Ensure you are using the latest version of OpenCore tailored for AMD systems.

2. Correct Kexts and Drivers:

   • Verify that you have the AMD-specific kexts such as AMD_Vanilla patches.
   • Use the Lilu.kext, WhateverGreen.kext, and VirtualSMC.kext or FakeSMC.kext.

3. Ryzen CPU Configuration:

   • Configure your config.plist for a Ryzen CPU, which involves using the correct SSDTs and kernel patches.

4. Graphics Compatibility:

   • Ensure WhateverGreen.kext is up to date for compatibility with your RX 6700 XT.
   • Set the npci=0x2000 or npci=0x3000 boot argument if you face PCIe related issues.

5. ACPI Configuration:

   • Ensure that your ACPI patches are correct. You may need SSDT-EC and SSDT-USBX for proper functionality.

6. BIOS Settings:

   • Disable CSM or Secure Boot.
   • Enable Above 4G Decoding if available.
   • Set the PCIe mode to Gen3 for the slot your GPU is in if you face compatibility issues.

7. Boot Arguments:

   • Add agdpmod=pikera to the boot arguments to avoid black screen issues with RX 6000 series GPUs.

8. FileVault:

   • Disable FileVault if enabled, as it can cause issues on Hackintosh systems during installation.

9. USB Mapping:

   • Proper USB mapping is crucial; incorrect mappings can cause boot failures.

10. Clear NVRAM:

    • Clear NVRAM through the OpenCore boot menu to resolve any issues from previous boot attempts.

Analysis of the Error Message:

The screenshot provided indicates a failure during the early boot process, potentially related to kernel extension loading or ACPI configuration. The error messages suggest issues with loading the kernel cache (EB.LD.LKC*).

Feedback and Support:

• Share your EFI folder configuration (without serial numbers) on forums like r/hackintosh for community support.
• You might find it beneficial to search for others with a similar setup who have documented their EFI configurations.

Reminder:

• Tweaking a Hackintosh EFI can be a trial-and-error process, especially with newer versions of macOS and AMD systems.
• Always keep a USB stick with a working EFI as a backup to boot your system in case of issues.

Given the complexity of AMD systems with Hackintosh and the fact that macOS is not natively designed to support these CPUs or newer GPUs like the RX 6700 XT, you may need to seek assistance from communities specializing in AMD Hackintosh builds.
