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.

The DMG file will now be burned to the USB drive, and you can use it to do program installations. Disk Utility has a good burn success rate, so hopefully you won't have to repeat the process to get it right. Method 2: How to Burn DMG to USB in Windows 10 (Bootable). DMG files could be mounted as a volume in Finder. Currently DMG files on Mac OS are used to distribute software packages. When software package in DMG file is opened it instructs Mac OS Finder to change its window in a way it is easy for user to copy application to the right folder.

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!

How To Use Dmg File On Mac X

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.

Method 3: Create macOS High Serria/Mojave Bootable USB on Windows 10/7

Another way to create macoS bootable disk on Windows is using a tool called DMG2IMG along with Windows command prompt. It requires a bit of a workaround, but even novice users can learn to burn a DMG file to a disk to create bootable media for a macOS installation. Just make sure you follow the instructions below carefully.

Step 1. Download DMG2IMG and install it in your Windows PC. Open File Explorer and go to the folder containing the DMG2IMG program, then right-click and select 'Open command windows here.'

Step 2. Type the following command and hit Enter: dmg2img [sourcefile.dmg] [destinationfile.iso]

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.

As you can see, this is a bit of a workaround because DMG files aren't natively supported in Windows. Likewise, ISO files aren't fully supported in macOS. However, you can use this method to create a macOS installation disk in Windows. If you want a much simpler solution, then review the next method shown here.

Summary

If you ask us how to create a bootable macOS installation disk, this is the method we recommend. There's no confusing command line work involved, you don't need a bunch of additional software utilities to get the job done, and the high accuracy of the application ensures that you won't be wasting disk after disk trying to burn the installation media for macOS onto a disk. Use WizDMG as a quick and painless way to create a macOS installation disk in a very short time.

What is a DMG file?

A DMG file is a mountable disk image used to distribute software to the macOS operating system. The file is typically downloaded from the Internet by a Mac user, then double-clicked to install an application on the computer.

Today, software developers typically build and distribute applications for Mac users as DMG, .APP, or .PKG files. DMG files are especially common since their contents can be verified upon installation to ensure they have not been tampered with and they can also be compressed to reduce the size of the installer.

When a Mac user downloads a DMG file, he can simply double-click it to open it with the DiskImageMounter utility that comes with macOS. When the DMG file is opened, it mounts a virtual disk on the desktop and in an Apple Finder window as if it was a CD or a USB flash drive that was just inserted into the computer.

How To Use Dmg File On Mac Pro

In the Finder window, the Mac user can double-click the program icon, which is an APP file, to run the app. Or the Mac user can drag the program icon to the 'Applications' folder icon to move it to the 'Applications' directory in macOS.

After the software stored in the DMG file is installed, the DMG file is no longer needed. Therefore, DMG files can be deleted after installing the software.

Run Dmg File On Mac

While DMG files are Mac-specific and not intended for use in Windows, there are several Windows programs that can extract their contents or convert them to other formats. Some programs include 7-Zip, PeaZip, and DMG2IMG.

NOTE: The DMG format replaced the .IMG file format, which was previously used in Mac OS Classic.
