Jan 03, 2020 Quick note: You want to do this before creating the bootable media because there is a good chance that the drive was formatted using a Windows device. If this is the case, chances are that it’s using a MBR partition, and the USB drive needs a GPT partition to work on a Mac. How to Create Bootable USB Installer for Mac OSX on Windows 10? Mukhtar Jafari 0 In our previous topics, we have told you that how you can create a bootable USB flash drive for Mac OS Using Unibest & DiskMakerX, perform a clean installation of Mac OS, and upgrading Mac OS Yosemite to the newest and update to date version El Capitan.

Learning how to create a bootable macOS installation disk can be helpful in a variety of situations. Rather than download and install a new OS from Apple's servers each time, it can be used for multiple installations on different machines. It can also help in situations where the operating system is corrupted or installation from app store shows errors.

To create a bootable macOS installation disk, you have to burn the DMG file to a USB drive as CD/DVD is not available for Mac computers. Here's how to do it from text commands and using a purpose-built software called WizDMG. You will first need to download the DMG file for the macOS version you wish to install. For example, if you want to create a bootable macOS Mojave installer, you will need the DMG file for macOS Mojave. Once the file has been downloaded to your PC, you can proceed with one of the bootable disk creation methods shown below.

Method 1: How to Create Bootable USB Installer for Mac via Commands

macOS (formly named Mac OS X) is just a variant of popular Unix based operating system. This means a lot of daily and advanced tasks on Mac can be done via text commands such as creating bootable USB installer for Mac. However, this could be a lot of challenges if you had no clue about commands and I suggest taking a look at the other solutions in this post to avoid messing up the computer with the wrong commands.

Step 1. Search macOS name in app store (Mojave, High Serria, EI Capitai). Click 'Get' button to download the installer image on your Mac. The downloaded file will be located in Application folder.

Step 2. When the download is completed, the installation windows opens automatically, just close the window and go to Application folder. You will find a file started Install, such as Install macOS Majave.

Step 3. Now connect an external flash drive with more than 16G free space. And backup the data in that USB drive as the installer erase all content from it. Open Disk Utility app and format the USB drive with APFS or Mac OS Extended.

Step 4. Open the Terminal app and copy-and-past the following commands to make a booatble USB installer from macOS image:
For Majove: sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
For High Serria: sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
For EI Capitan: sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app

Step 5. Input the admin password when being prompted. And wait for the booatable disk being created. When it is done successfully, you will receive a message shown in above screenshot.

Unconfortable with text commadns and prefer doing it in a simple way? The second suggestion is more user friendly!

Method 2: How to Make Bootable USB from macOS with WizDMG

WizDMG fills a huge gap in Windows not supporting DMG files. It is a desktop utility supporting Windows and Mac. It allows you to directly burn DMG files to disk in order to create a bootable macOS Mojave installer or a boot disk for any macOS version.

WizDMG offers an intuitive interface with no clutter and full functionality to handle DMG files. Apart from burning such disk image files to DVD/CD or USB, it also gives you edit options where you can add and remove files from within the DMG file, rename DMG files and even create DMGs from files and folders on your desktop. This software application has been created for novice users as well as experts. It is easy to use, has a very high burn success rate and will help you create a bootable macOS installer in no time. Follow the instructions below:

Step 1Install WizDMG

Step 2Create Bootable USB from macOS Install Image

Click on Load DMG to import the macOS installation file into the application. Insert a USB (16G free space) and click on the 'Burn' button next to the appropriate media type.

The important thing to remember here is that you now know how to create a macOS installer in Windows. There aren't a lot of options out there because of the compatibility issues between Mac and Windows environments. That means converting DMG to ISO and back again to DMG leaves the door open for corrupted files and incorrectly burned bootable media, which defeats the whole purpose because it might not even work in the end.

Apple recently released the 10.13.6 version of the Mac OS High Sierra. Mac users can download this update from the Apple Store and update their existing systems.

Step 3. Now that the DMG file has been converted to ISO format, you can use the following command to burn it to a disk. Before that, insert a disk into the optical drive: isoburn.exe /Q E: 'C:UsersUsernameDesktopdestinationfile.iso'

Step 4. This command utilizes the Windows native disk image burner to burn the ISO to the disk in your optical drive. The ISO file can't be used directly in macOS, but it can be mounted as a virtual drive. Once you do this, you can convert it back to DMG using Disk Utility in Mac. You can then use this as your bootable macOS installer.

Before you start

Before you get started, make sure you have a thumb drive with at least 15GB of storage, or a spare external hard drive (one you aren't planning to use for anything else). You'll also need to download macOS Catalina and ensure that it's sitting in your Applications folder.

Note: After macOS Catalina has downloaded, it will automatically launch the installer to begin the installation process. Quit the installer when this happens.

And please: Don't forget to back up your Mac before you do anything.

How to format your external drive for macOS Catalina

You'll need to start with a clean thumb drive or external hard drive in order to make it a bootable drive.

Plug the thumb drive or cable for your hard drive into the appropriate port on your Mac.
Click on Finder in your Dock to open a Finder window.
Select Applications from the list on the left side of the window.
Scroll down and double-click on Utilities.
Scroll down and double-click on Disk Utility.
Select your thumb drive or external drive under External.
Click on the Erase tab at the top of the window.
Note the name of your external hard drive (probably 'Untitled') because you will need it when you create a bootable drive. If you have more than one external drive with the same name, you will need to rename the drive you are using as a bootable installer now.
If your Mac is using AFS+, select Mac OS Extended (Journaled) from the format list. If your Mac is using APFS, select APFS from the list of options.
If Scheme is available, select GUID Partition Map.
Click Erase.
Click Done when the process is complete.
Close the Disk Utility window.

Your thumb drive or external hard drive is now ready.

Click on Finder in your Dock to open a Finder window.
Select Applications from the list on the left side of the window.
Scroll down and double-click on Utilities.
Scroll down and double click on Terminal.
Recall the name of your formatted external drivewhen entering the following text into Terminal. If it is not named 'Untitled,' you will need to change the command syntax for the pathname where it says: Volumes/MyVolume. The name of the drive can't have any spaces and it is case sensitive.
Enter the following text into Terminal (Don't forget to change the name 'Untitled' in the text below to the actual name of your external drive. Names are case sensitive and can't have any spacing.):
sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Hit the enter/return key.
Enter your administrator account password. This is the password you use to make changes on your Mac or log in. No text will appear in Terminal when you enter the password.

The process could take a very long time, depending on the drive. When it is done, the Terminal window will report 'Done.'
