How to Fix OpenCore does not show boot option

Graphics issues usually stem from an unsupported GPU, missing acceleration patches, or incorrect boot arguments.

Quick Fix Steps

  1. Verify GPU support: Check if your GPU is natively supported via WhateverGreen docs.
  2. Update kexts: Ensure Lilu and WhateverGreen are current.
  3. Check boot arguments: Add -v keepsyms=1 debug=0x100 for debugging, or agdpmod=pikera for AMD.
  4. Test Metal: About This Mac > System Report > Graphics.

Verification

  • Graphics acceleration is smooth.
  • Metal is reported in System Information.

Hi! I'm trying to install Big Sur to my Probook 440 G1 but OpenCore always not detecting MacOS Big Sur Install (only windows and reset NVRAM option shown). Is there anyway to fix it? I'm using OpenCore 0.6.4.
