How to Fix Cannot boot into macOS Installer.

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:

Hi, I made my Unibeast USB with the EFI being Clover, but when I boot into the macOS Installer, I get no activity from the USB Drive, the screen is hanging at the Apple logo, and nothing else. My CPU is a 6 Core AMD Ryzen 5 5600x Processor and my GPU is an AMD Radeon RX 580.
