This guide will walk you through creating a bootable installer for macOS Monterey on a USB flash drive for the purpose of installing Monterey on a hackintosh compatible computer.
Part 1: Creating a Monterey USB Installer
To create a bootable macOS installer that works on a PC desktop or laptop we’ll need:
- Copy of macOS Monterey
- 16GB USB Flash Drive (Monterey takes up 13GB of disk space)
- Software to create a bootable copy of macOS Monterey
Step 1: Downloading macOS Monterey
On Mac? Easiest way to Monterey is from the Mac App Store
On Windows/Linux? Download macOS Monterey on Windows or Linux (coming soon)
Step 2: Formatting the USB Drive
In order to create a bootable macOS installer that works on PC the USB flash drive must be formatted as Mac OS Extended (Journaled) which adds a second hidden EFI partition where the hackintosh bootloader is stored.
- Insert a USB Flash Drive
- Open Disk Utility
- Click View from the top silver menu bar
- Select Show All Devices
- Select your Flash Drive on the left column under External
- Click Erase
- Set the following settings:
- Name: Hackintosher
- Format: Mac OS Extended (Journaled)
- Scheme: GUID Partition Map
- Click Erase (If you get an error use First Aid in Disk Utility first)
- Click Done upon finish
Step 3: Transferring the Monterey Installer
Afterwards the the Monterey Installer downloaded from the Mac App Store is ready to be placed on the USB drive using Terminal.
- Verify Install macOS Monterey is in the /Applications folder
- Open Terminal through spotlight or launchpad
- Paste the following into Terminal entering your password if prompted:
sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/Hackintosher /Applications/Install\ macOS\ Monterey.app --nointeraction
sudo /Applications/Install\ macOS\ Monterey\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Hackintosher /Applications/Install\ macOS\ Monterey\ Beta.app --nointeraction
- Select OK if you get the prompt “Terminal” would like to access files on a removable volume.
- Do not close Terminal, the installer will transfer over slowly and can take awhile especially if you are using USB 2 bus speeds
Part 2: Configuring EFI Partition for a Monterey Hackintosh
We will now mount the hidden EFI Partition created when the flash drive was formatted.
Mount EFI Partition
- Download OpenCore Configurator
- Open OpenCore Configurator
- Select Mount EFI under TOOLS
- Click Mount Partition for Install macOS….
- Click Open Partition (This is where the EFI Folder will go)
Create or Download a EFI Folder
An EFI folder can be created with either Clover or OpenCore.
If you’re updating a hackintosh from an earlier version of macOS the same EFI folder that worked before may not work in Monterey without changes for compatibility.
