Troubleshooting
Most OCLP errors are easier to reason about after you know the exact Mac model, target macOS, GPU class, and wireless hardware.
Verify against official docs
Mac Pro 2010 / 2012
Many setups depend on GPU and wireless card choices. Do not assume another user result applies to your hardware.
Do not jump to random patches before narrowing the failure category.
Write down model identifier, target macOS, and OCLP version.
Boot failures and post-install feature failures usually have different causes.
Graphics and wireless behavior may depend on root patch status.
Use official docs and issue context before changing EFI or system files.
