USB Installer
Requirements
The first thing we need to do, is to download the operating system of our choice, and a couple of tools to help finalise the USB installer.
Creating the Installer
Formatting the USB drive
Locate a USB drive of preferably 16 GB or more. Plug it into your reference computer and launch Disk Utility. Select the USB drive in the left sidebar and click on the button within the toolbar. Finally, when prompted, specify the values as seen below;
Installing the Installer
Once the formatting process is complete, you may launch UniBeast and follow the on-screen instructions in order to complete the USB installer. Refer to the application settings below during the process.
This process may take up towards half an hour to complete depending on your hardware.
Polishing Up
Before we're tempted to install the operating system, we must make a few alterations to the USB installer.
Configuring the EFI
Launch
, mount the EFI partition of the USB installer unless it has already been mounted for you by UniBeast. Open/EFI/Clover/config.plist with Clover Configurator and apply the following settings; HFS+ Filesystem Support
The clover bootloader comes with an alternative open source driver for HFS+ support for legal reasons. We'll want to use the official Apple HFS+ driver instead.
Download
into/EFI/Clover/drivers64UEFI. Additionally, remove the open source alternative - VBoxHfs-64.efi.
x99 Motherboard Support
If you're using a x99 motherboard, you must also replace the default OsxAptioFix driver bundled with the clover bootloader.
Download
into/EFI/Clover/drivers64UEFI. Additionally, remove the default - OsxAptioFix2Drv-64.efi.
