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
createinstallmediaby using this command in Terminal
sudo /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
