How to Fix Grey Screen with Cursor when Booting OCLP USB

Fixing Grey Screen during OCLP Boot

Sticking at a grey screen with a cursor means the OpenCore environment has loaded, but the macOS installer kernel is failing to initialize.

Possible Fixes:

1. Wait: On older Macs with slower USB ports, this screen can last up to 10 minutes. Give it time.
2. Reset NVRAM: A stale NVRAM can block the installer. Perform a 3-beep PRAM reset.
3. Check Model ID: Ensure you built the OCLP settings for the exact model you are targeting.
4. USB Port: Switch to a different USB port, preferably a USB 2.0 one if available.
