Mac OS X Mountain Lion is compatible with the following Macs:

Downloading macOS Mountain Lion:

To start, you'll need to grab a copy of macOS Mountain Lion. While you don't need a fresh install of macOS to use OpenCore, some users prefer having a fresh slate with their boot manager upgrades.

You can download macOS Mountain Lion from the App Store or with Munki's script. Alternatively, if you're just making a bootable OpenCore stick and not an installer, you can skip this step.

Formatting the USB:

If you're planning to create a bootable OpenCore stick, you'll need to format the USB drive before installing macOS. You can use the Disk Utility tool to erase the USB drive and create a new partition.

Getting Started with ACPI:

Before we dive into setting up the EFI, it's essential to understand how to work with Apple's proprietary file system, HFS+. This will allow you to access your files and folders more easily.

You can find more information on working with HFS+ in our article on Getting started with ACPI.

Setting up the EFI:

Now that you have a copy of macOS Mountain Lion, it's time to set up the EFI. The EFI (Extensible Firmware Interface) is responsible for booting your Mac and loading the operating system. To set up the EFI, follow these steps:

1. Open the Disk Utility tool.

2. Select the USB drive as the target disk.

3. Click on the 'Erase' button to erase the USB drive.

4. Create a new partition by clicking on the 'Partition' button.

5. Follow the prompts to create the new partition.

Once you've set up the EFI, you can start installing macOS Mountain Lion.
