How to Fix Stuck at "pci configuration begin"

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
  2. Ensure Metal acceleration is fully supported for your macOS version.
  3. Update Lilu and WhateverGreen to the latest versions.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

I used this tutorial: https://youtu.be/j-Cm30I_DEw

My System Specs: GPU: AMD RX570 4GB CPU: Ryzen 5 3600 MB: Gigabyte Aorus B550I Pro Ax SSD: SanDisk 240GB

In the tutorial it was said that you should disable CSM in the Bios, but if I do that, I cannot select the USB Stick for Booting, I can only see the Windows Boot Manager as a boot option.

Could CSM be the problem and if so how can I boot from the USB with CSM disabled.
