EFI folder should work on other macOS versions, but it was only tested with Big Sur

Everything works fine, but audio is handeled with voodooHDA because AppleALC causes kernel panic

Download this repo. Generate SMBIOS data with GenSMBIOS and set it in config.plist. Then copy to your EFI partition and that's it.

• Stable and reliable system
• working sleep
• fully working sound including DP

There are two ways you can install Big Sur:

1. If you have an already working macOS, download the Installer from the App Store and make a bootable Installer with createinstallmedia by using this command in Terminal: sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

2. If you are using Windows, use macrecovery.py from the offical OpenCore release package. Follow this guide to understand how it works.

After you have created a bootable Installer, copy the EFI folder to the EFI partition and set SMBIOS data generated with GenSMBIOS. Then install as usual. After the installation, mount the EFI partition of the installed OS and copy the EFI folder to its partition.
