With OpenCore Legacy Patcher(OCLP), the new GUI includes a convenient download menu for recent macOS installers. We will not be using the other features of OCLP, as they are not relevant to creating a hackintosh.
So to start off, you'll want to grab the latest OpenCore-Patcher-GUI.app.zip from:
For this guide, we'll be using the standard OpenCore-Patcher (GUI). Once downloaded, open the app and you should be greeted with this menu:
Download macOS Installer
First we'll want to select the "Create macOS Installer" button. This will present you with 2 options:
For this example, we'll assume you'll need an installer. Selecting this option will download Apple's Installer Catalogs and build a list for you to choose:
Since OCLP only supports Big Sur and newer, only those entries will be shown. For this example, we'll select macOS 12.1 Monterey. This will download and save the macOS installer to your Applications folder.
Downloading the Installer
Requesting to install
Write installer to USB drive
Once finished, you can proceed to write the installer onto a USB drive.
Note: The entire USB drive will be formatted
Select Downloaded Installer
Select disk to format
Now OCLP will start the installer flashing - copying macOS to the USB drive!
Open EFI Agent from its Menu Bar Icon and click on the downward triangle next to the USB drive you wish to use (SanDisk Ultra in this example).
After authenticating, you will see the EFI partition of your USB drive in the Finder.
Drag to copy the EFI folder previously created and configured with OCAuxiliaryTools from the Desktop to the EFI partition on the USB drive.
This step completes the creation of a hackintosh bootable USB drive with the macOS installer and the OpenCore EFI folder on it. - You may want to add some tools such as OCAuxiliaryTools and EFI-Agent to the USB drive, as these will be useful during post-install configuration.
