What to Do When Your Mac Shows a Blank Screen After OCLP

A blank screen after an OCLP install is usually recoverable. The safest move is to reset boot settings and return to the OpenCore picker.

Step-by-Step Recovery:

  1. Power off fully: Hold the power button for 10 seconds, then wait 30 seconds.
  2. Reset NVRAM: Start while holding Option + Command + P + R, or use Reset NVRAM in OpenCore if visible.
  3. Boot with Option: Hold Option at startup and choose EFI Boot/OpenCore, then the macOS installer or internal disk.
  4. Use external recovery: If nothing appears, boot from a known-good macOS USB installer.
  5. Reinstall patches: Once booted, rebuild OpenCore for the exact Mac model and run Post-Install Root Patch.
