Weird Quirks and Shit I need to fix

• Phase 1 boot is stretched, could be firmware limitation
• screen glitching at boot phase transition, non issue for me
• haven't set up OC Boot Picker as i don't need it done
• USB 3.0 Mapping DONE
• fn key support is available with Karabiner-Elements
• pressing fn+f8 (Projector button thing) on lock screen, or w/o Karabiner-Elements COMPLETELY SHITS YOUR DISPLAY, DO NOT RECCOMEND.
• Playing DRM-Controlled movies on safari, Apple TV+ app is not possible, oc limitation. use firefox/chrome

BIOS Settings

• DVMT-PRE-ALLOC: 64M

How to actually install macOS Big Sur?

  • macOS Recovery Files with macrecovery.py (found in utilities folder)
  • EFI files
• appropriate installation medium (refer to "Creating the USB" part on OpenCore Install Guide)
• copy in files
• Create SMBIOS data for MacBookAir6,2 with GenSMBIOS (found in utilities folder)
  • make sure that the s/n is not registered
• fill in SMBIOS data on PlatformInfo/Generic
• example of SMBIOS data and where to fill it in
