Graphics issues usually stem from an unsupported GPU, missing acceleration patches, or incorrect boot arguments. Below is a systematic approach to diagnosing and fixing them.
Step 1 — Verify GPU Compatibility
Check if your GPU model is natively supported in your target macOS version. AMD Radeon RX 400/500/5000 series generally work natively. NVIDIA support ended at High Sierra for most cards.
Step 2 — Update Essential Kexts
Ensure Lilu and WhateverGreen are installed and current.
Step 3 — Configure Boot Arguments
Add -v keepsyms=1 debug=0x100 for debugging. For AMD cards add agdpmod=pikera.
Step 4 — Confirm Metal Support
Open About This Mac > System Report > Graphics/Displays. Metal support should be listed.
Expected Results
- Graphics acceleration is smooth
- Correct resolution on all displays
- No GPU-related kernel panics
