Alternatively, you can use GParted to create Mac OS Extended (Journaled) partitions and convert to APFS using Disk Utility. If the latest version does not work, try the older versions. Please check the Changelog.txt file for more details.: Cloverv2.4kr4674. MacOS Mojave 10.14.0.: macOS High Sierra 10.13.6. In this guide we’ll go through how to create an install drive from the macOS Mojave 10.14 application, either general release or beta. This will allow you to perform clean installs, install to multiple machines without re-downloading, boot the system externally for troubleshooting, and more. Step 5 – Detach the Sparse Disk of your new macOS install media. So we can create a macOS install media DMG file, we will need to detach the Sparse Disk: Again in Terminal (the name “ Install macOS Mojave ” depends on the macOS version you’re creating install media for – if unsure, see what is in the “/Volumes” directory): sudo.

#!/bin/bash
# Install OSX Mojave through App Store. After downloading, the 'InstallESD' is automatically mounted, which causes this script to fail.
# Therefore, '/Volumes/InstallESD' should be unmounted before running this script!
# Summary of instructions
#1 Download Mojave from App Store
#2 open terminal and run 'umount /Volumes/InstallESD'
#3 make script executable: 'chmod +x make_mojave_iso.sh'
#4 Run './make_mojave_iso.sh'
#5 After running this script, if successful, you end up with 'Mojave.iso' on your desktop

Mojave is still one of the most popular macOS desktop operating system in late 2020, which occupies around 20% market share of entire macOS. There are still millions of Macs or Hackintosh running Mojave as its primary OS. However, if the computer was crashed or broken, you have to reinstall macOS Mojave on it to solve the problem.

In this post, we will share a detailed tutorial on how to create a macOS Mojave bootable USB installer. At this time, we will use a Windows PC (Windows 10 laptop) as you are unable to get into the Mac. Honestly, it is much easier to create macOS bootable USB on Mac with createinstallmedia command in Terminal. You can refer to Part 6 of this tutorial if you have a Mac to do this.

Part 1: MacOS Mojave Hardware Requirement

If Your Mac was shipped with Mojave in default, then there is no need to check hardware compatibility at this time. For system downgrade or upgrade, you have to make sure your Mac hardware meet the minimal requirement for installing macOS Mojave.

For Mac:

  • MacBook Pro (Mid 2012 or newer)
  • MacBook Air (Mid 2012 or newer)
  • MacBook (Early 2015 or newer)
  • Mac mini (Late 2012 or newer)
  • iMac (Late 2012 or newer)
  • iMac Pro (2017)

However, if you prepared to install macOS Mojave on a Hackintosh, the requirements are different and much complex. You should do your homework more carefully. Below is an overview requirement.

For Hackintosh:

Create Macos Mojave Bootable Iso

  • CPU: Intel 8th or 9th Generation
  • Memory: 4 GB RAM
  • Storage: 128 GB SSD or HDD.
  • Motherboard: Compabible with CPU (Asus, MSI Preferred)
  • Graphics: AMD Radeon Recommended

Part 2: Download macOS Mojave DMG File

macOS Mojave has two types of installation format. One is via Install Mojave App where you can directly download from Mac App Store. This option is not available on Mac with a new version of macOS that is newer than Mojave.

The other installation media is via Mojave dmg file, which contacts all the files and boot information for installing macOS Mojave in a compressed structure. However, you need to burn dmg to USB first before it is used as a bootable media. Now, you can download macOS Mojave DMG file the following resources:

Download Link 1: https://archive.org/download/macOS_Mojave.dmg

Part 3: Create macOS Mojave Bootable USB Installer on Windows 10 PC

You have completed the preparation process in above steps and it is time to create a bootable Mojave USB installer from the download dmg file. Unfortunately, the USB would be bootable if just simply copying the dmg file to USB drive without additional actions because the booting code is not written to USB via file copy. Instead, you should use third-party software to help you create a macOS Mojave USB drive from DMG file.

UUByte DMG Editor is such a tool for burning dmg file to USB drive. It will copy all installation files and write boot information to USB drive as well. After burning, the USB is bootable and can be used as a media to install macOS. The following is the details for creating macOS Mojave bootable USB drive.

Step 1: Click the Download button and save the .exe file on your Windows PC; then double click it to start the installation process.

Step 2: Insert a USB drive into the PC and open DMG Editor software from desktop shortcut. Now, click Next button at the right side of Burn module.

Step 3: Now, you need to import the downloaded Mojave dmg file into the program and choose the USB drive name from drop-down menu.

Step 4: When the preparation is done, click Burn button to start burning macOS Mojave dmg file to target USB device. You have to wait for 5-10 minutes for this.

This is one of most reliable ways to create macOS Mojave bootable USB drive on a Windows PC. You can use DMG Editor on latest Windows 10 as well as Windows 8/7/XP.

Part 4: Install macOS Mojave from USB Drive on Mac

After creating macOS Mojave bootable USB drive, it is the right time to install Mojave on your Mac. If possible, make sure taking a backup of important data on your Mac. The installation process will format the drive and this will delete all your personal data and apps from Mac.

To get started, please connect the USB drive to Mac and power on the computer. Keep pressing the Option key and you see the Startup Manager in a few seconds. Click on the USB drive name with your mouse to enter into installation page. Next, select the internal drive and finally click Continue button to begin the installation process.

Note: For installation on a Hackintosh, you need additional tool to configure the boot loader, such as OpenCore or Clover. After that, plug the USB into Hackintosh and set USB as the first boot device in BIOS. By doing this, you will manage to get into Mojave install wizard.

Part 5: Possible Issue and Fix

Create Macos Mojave Iso

According to our research, there might be a few issues during this process, which were reported by online users. Below is a list of most common issues you may come across. Please don't be scared as we also share possible fix to help you out!

USB Not Showing up in Startup Manager: If the USB drive burned with DMG Editor did not show up in Startup Manager, it means the burning process failed. The most possible reason is that the dmg file was corrupted, you need to download it from another source and burn it again.

No available drive for installation. Mojave is built with APFS but the old Macs come with HFS or HFS+. You have to boot into macOS Recovery mode and format the drive to APFS with Disk Utility app.

It could be more issues with Hackintosh and we don't have less epxerience on this topic. Please go to Hackintosh blog or forum for more accurate solutions.
