Here you go!
OC-0.6.3 working EFI for Big Sur. This is a slight modified version of
@Mikorist 's one.
- You have to fill PlatformInfo section by yourself
- UpdateSMBIOSMode is set to "Custom" and Kernel->Quirks->CustomSMBIOSGuid is set to true: this won't pass SSDTs to other OSes and you'll be able to boot Windows/Linux "natively" from OC. Breaks BootCamp
- OpenCanopy is enabled but you need to fill OC/Resources subfolders
- Should work with Catalina too
I am working on a new EFI with some custom SSDT, proper USB mapping, VoodooPS2 (Enables touchpad gestures for me) and AppleALC (microphone issues atm). I am facing sleep issues, so I won't share it yet.
@Mikorist if you want to help me improve the EFI, send me a PM.
