How to install
Download this repo and place the EFI folder into your internal drive’s EFI partition… That’s it.
How to Install macOS Monterey
There are two ways you can make a USB installer:
-
Have a working install of macOS, download the Installer from the App Store, then make a bootable Installer with
createinstallmedia
by using this command in Terminalsudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
-
If you are using Windows, use macrecovery.py from the offical OpenCore release package.
After you have created a bootable Installer, copy the EFI folder to the EFI partition of the installer drive and install as usual (GUID Partiton Map; APFS). After the installation, mount the EFI partition of the installed OS and copy the EFI folder to its partition.
Running Big Sur and Catalina
If you want to run Big Sur/Catalina, you have to replace AirportItlwm with the one appropiate to the version of macOS.
