This guide will walk you through creating a bootable flash drive installer for macOS Mojave which is started by first formatting the a USB flash drive and transferring the Mojave Installer over and then creating the boot partition necessary to run the Mojave Installer on a hackintosh on a non-Mac PC.
Part 1: Transferring Mojave Installer to USB
To get a working Mojave installer onto a USB flash drive it must first be formatted into a scheme that allows for an EFI Partition. Afterwards the the Mojave Installer is ready to be placed on the USB drive using is Terminal.
Step 1: Formatting the USB Drive
In order to transfer the Mojave installer the USB flash drive must first be formatted into a usable scheme that allows for an EFI Partition.
- Insert Flash Drive
- Open Disk Utility
- Select the Flash Drive on the left column
- Click Erase
- Set the following settings:
- Name: Hackintosher
- Format: Mac OS Extended (Journaled)
- Scheme: GUID Partition Map
- Click Erase
- Click Done upon finish
Step 2: Transferring the Mojave Installer
- Open Terminal through spotlight or launchpad
- Paste the following into Terminal entering your password if prompted:
sudo /Applications/Install\ macOS\ Mojave\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Hackintosher --applicationpath /Applications/Install\ macOS\ Mojave\ Beta.app --nointeraction
- 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 Mojave Hackintosh
If this flash drive is being made for a hackintosh there is a second part required where we must configure the boot partition of the flash drive to boot off non-mac devices. The boot partition is also called the EFI Partition and within the hidden EFI partition is a folder called EFI. The EFI folder contains the boot configuration files. To access the EFI partition it must be mounted.
Mount EFI Partition
With the EFI partition mounted you now have two options. You can either make your own EFI folder or you can save time and a potential headache by using the preconfigured EFI on this site. If this is your first time I recommend going with the preconfigured EFI folder.
- Download Clover Configurator
- Open Clover Configurator
- Select Mount EFI under TOOLS
- Click Mount Partition for Install macOS….
- Click Open Partition (This is where the EFI Folder will go)
Option 1. Generate your own Mojave EFI Folder
To generate your own EFI folder for Mojave you need to download Clover EFI Bootloader, install it onto the flash drive with the proper selections and then add addition kext files to be able to boot the installer successfully.
Step 1. Install Clover EFI Bootloader
To generate a working EFI folder we must first configure Clover EFI Bootloader with the proper settings for macOS.
Step 2. Add Boot Kexts for Mojave
For the installer to work there are a number of .kext files you should add and a port limit patch that is necessary to use USB 3 flash drives for those without an SSDT for USB.
xThere are a number of recomended kexts that will help you boot the macOS installer for Mojave.
Option 2. Use preconfigured Mojave EFI folder
Now we are going add the hackintosh EFI folder to the partition you mounted:
- Delete the folder called EFI in the partition you mounted
- Download Hackintosher-Mojave-10.14-EFI.zip
- Unzip Hackintosher-Mojave-10.14-EFI.zip
- Copy the unzipped EFI folder
- Paste the EFI folder into your mounted EFI partition or /Volumes/EFI
