Started with a GTX 970 on Ventura using OpenCore Legacy Patcher. What followed was over a year of CPU power management issues, GPU artifacts, kernel panics, missing boot logos, and no hardware acceleration.
The breakthrough came when I stopped layering fixes and cleared every OCLP request, then rebuilt the config from scratch: WhateverGreen patches, framebuffer edits, AGPM injection. It finally booted clean with acceleration. Still learning why each patch works.
