How to Fix OC Slow Boot speed with iGPU + dGPU

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 model is natively supported in your target macOS version via WhateverGreen documentation.
2. Update kexts: Ensure Lilu and WhateverGreen are current and loaded before other GPU-related kexts.
3. Check boot arguments: Add -v keepsyms=1 debug=0x100 for debugging, or agdpmod=pikera for modern AMD cards.
4. Test Metal support: Open About This Mac > System Report > Graphics and confirm Metal is listed.

Verification

• Graphics acceleration is smooth (not CPU-bound).
• Metal is reported in System Information.
• No GPU-related kernel panics on boot.

My question is weather the boot time latency is known issue compared to boot time with only dGPU. Any suggestions are appreciated greatly guys. Thanks I will update soon the actual boot times with stopwatch to get the exact time difference between two modes. submitted by /u/walkingjune [link] [comments]
