How to Fix Since Big Sur, boot stops with this message, not everytime, maybe 1 out of 2 time. I'm not using any EGPU. Did some research but can't solve that. Any ideas? (more in comment)
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
- Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
- Ensure Metal acceleration is fully supported for your macOS version.
- Update Lilu and WhateverGreen to the latest versions.
Verification
- Reboot and verify if the functionality is restored and stable under typical usage.
