Installing macOS

Creating the macOS Installer

Start by creating a vanilla macOS installer, refer to Dortania's Creating the USB.

You may also use createinstallmedia if you already have a Mac.


Often as above, the project will defer universal steps to Dortania links. Hence, this repository is meant to be used in conjunction with their guides.

EFI Partition

  1. Make the following changes to config.plist within the EFI folder.

    • ShowPicker to YES
    • If your machine has a vanilla (unmodded) BIOS, merge /patches/ OpenCore Patches/ Vanilla BIOS.plist with config.plist


It is generally a good idea to keep the install media around. As you tweak your own OpenCore config.plist, things may break and you will not be able to get back into macOS using the system's OpenCore. In those times, you can use the install drive to boot into macOS.

  1. Mount the installer media's EFI parition. You may do this via the command line with diskutil or via a utility like corpnewt/MountEFI.

  2. Copy the EFI folder into the installer media's EFI partition. Remember that the top directory level should be EFI.

  3. Boot into the macOS installer envrionemnt using the media. Format target disk as APFS using Disk Utility and complete installation.

  4. Once macOS has been installed, boot the installed macOS paritition with the existing installer USB and complete new user setup.

  5. Copy EFI onto the macOS drive's EFI partition. Set ShowPicker to NO for a cleaner boot experience. You can still access the boot picker by pressing ESC during boot time.


At this point, your machine should boot into macOS without anything attached.
