Troubleshooting Boot Issues on AMD Hackintosh with Ryzen 5 5600X and RX 6750XT

Based on the screenshot you provided, it seems like your AMD Hackintosh is experiencing a boot issue. The verbose output indicates that there are NVMe-related messages and a mention of a previous shutdown cause, but the exact reason for the boot halt isn't entirely clear from the provided lines. However, there are some standard troubleshooting steps you can take:

1. Check NVMe Drives: The log mentions "Successfully initialized NVMe drive" which is good, but ensure that your NVMe SSDs are formatted correctly and that the EFI partition is set up properly.

2. Review Kexts and Boot Args: The mention of "NootRX" suggests you may be using a non-standard setup or guide. Typically, WhateverGreen.kext is recommended for AMD GPU setups. Ensure that you're using the correct version of WhateverGreen and that it's configured properly in your config.plist.

3. Examine ACPI Patches: For Ryzen systems, proper SSDT patches are crucial. Verify that your SSDTs are appropriate for your Ryzen 5 5600X and B450M motherboard.

4. Check GPU Compatibility: The RX 6750 XT is a relatively new GPU model. Ensure that it's supported in the version of macOS you're trying to install and that you have the correct boot args for AMD GPUs.

5. Ensure Proper BIOS Settings: Go through your BIOS settings again and ensure that settings like CSM are disabled, and that you're using UEFI boot mode. Also, check that your RAM settings/XMP profiles are compatible with macOS.

6. Reset NVRAM: Sometimes issues can be resolved by resetting the NVRAM, which can be done from the OpenCore boot picker.

7. Use a Known Good EFI: If you have access to a known working EFI folder for a similar hardware setup, try using that as a baseline and adjust for your specific hardware.

8. Consult the Hackintosh Community: Forums like r/hackintosh, Hackintosh Discord servers, or websites dedicated to AMD Hackintoshes can be good resources for help with specific issues.

Given the complexity of Hackintosh setups, especially with newer AMD hardware, it may take a few attempts to find the right combination of kexts, drivers, and configurations.
