Following your guide, I get a black screen immediately after OpenCore picker #65

Describe the bug Attempting to install Big Sur with OpenCore 0.7.4 RELEASE results in a black screen immediately after picking the USB/DMG

This happens both when I copy OpenCore 0.7.4 to my USB and replace files with this repo, and only copy EFI from this repo to the USB

To Reproduce Steps to reproduce the behavior:

  1. Follow all steps in guide word for word. Only difference is appending download to the end of the command since macrecovery.py requires an action now ./macrecovery.py -b Mac-E43C1C25D4880AD6 -m 00000000000000000 download. Another attempt included -os latest at the end
  2. Double checked BIOS settings, all of which match up to this guide.
  3. Boot the USB in UEFI. OpenCore successfully boots.
  4. Pick the USB/DMG, black screen until laptop reboots about two minutes later

Expected behavior Apple logo/setup screen (or verbose boot log) to appear

Screenshots None
