Download and build macOS Installers

This document is centered around downloading and writing the macOS installer to a USB drive. If you're already familiar with how to do this, you can skip this section.

• Note: A 32GB drive is recommended, later versions of Sonoma and Sequoia cannot fit installer and patches to a 16GB disk. 16GB drive may work for older versions.

Creating the installer

To start off, you'll want to grab the app:

• OpenCore Legacy Patcher Release Apps

Once downloaded, open the app and you should be greeted by the main menu.

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. Select the "Download macOS installer" to get you a list of installers. Click to download the version you want.

Once the download is 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 the patcher will start the installer flashing!
