Hi! To be clared first, the pre-built OpenCore from this repository is specifically target for model Lenovo Legion R7000P2020H (82GR). Its compatibility with other models cannot be guaranteed due to hardware differences between generations and models, althought they might within the same product line. I can only offer some general suggestions here:

  1. Are you in macOS 14.4 Beta? It's a known problem that iGPU Driver NootedRed.kext won't work on macOS 14.4, see: ChefKissInc/NootedRed#226
  2. If black screen occur during system installation or first time booting, please disable NootedRed.kext untill you finished all installion process and get into desktop. It's a known problem. Disable it temporarily every time you gonna install or upgrade macOS.
  3. Try reset NVRAM.
  4. Maybe bad kext loading order , try to do a OC Snapshot to your config.plist using ProperTree
  5. Maybe XHC0 problem, follow this guide to disable:

Known Problem 4: The system fails to start and gets stuck at a certain point occasionally

  • Temporary solution: Press and hold the power button to force shutdown, then try restarting again. If it doesn't work, try forcing restart multiple times.
  • Permanent solution: Disable XHC0 (ACPI->check SSDT-XCH0-DISABLE.aml) & disable modified XHCI driver (Kext->uncheck GenericUSBXHCI). Note: This solution will disable two USB ports (top C port & left A port)
  1. Maybe bad ACPI patching, you can get yours following this guide, and add bumblebee-method ACPI patch to disable dGPU.

Closing this issue due to non-targeted models.
We can still discuss under this issue. :)
