A DMG file is essentially Apple's format for mountable disk images in Mac OS X (macOS) computers. When opened, it mounts a virtual disk on the computer, and is normally used for installing new applications. DMG file is usually encrypted and compressed, unlike ISO, which is an uncompressed disk image format.

Part 1: How to Burn DMG to USB on Mac for Free (Disk Utility)
The native disk image utility on Mac is ideal for burning a DMG to a USB drive. Once you burn the file to the drive, this drive can be used to install the associated application on any other Mac system. The process may vary slightly depending on which version of Mac OS X your computer is running, but the steps below will give you a fair idea of how the process should be carried out.
Step 1: Go to Applications >>Utilities >>Disk Utility and click on it to launch the program.
Step 2: On the left, you'll see all the available drives. Insert the USB drive and watch as it appears on that list.
Step 3: Now open a Finder window and locate your DMG file. Drag and drop it under the drive names in the Disk Utility app.
Step 4: Select the file, and then click on 'Burn' in the same window. In the popup that appears, select your destination drive, which is the USB flash drive you want to burn the DMG file to. Click 'Burn' in the popup window.
Once the process is complete, remove the USB stick and use it to install the application associated with that DMG on any other Mac computer.
Pros:
- Totally free.
- No need to install other apps.

Part 3: Convert DMG to ISO and Burn ISO to USB
In certain instances, you may want to use a Windows computer instead of a Mac, which means you won't have the disk utility. Besides, Windows can't natively handle DMG files, so you will need to convert it into an ISO disk image that Windows can work with. Follow the steps below to do this.
Step 1: Download the DMG file and then convert it to ISO using a free online conversion service like YouConvertIt.
Step 2: Once you do this, you can use another utility like ISO Editor to burn the ISO file to a USB drive.
Remember, even if you convert the DMG to ISO, it's still Mac-compatible only, so you can't use it to install the program on a Windows system. However, it's helpful when your own system is a Windows PC and you want to burn the DMG file to a USB drive. In this case, you will need to convert it back to the DMG format for the installation.
Pros:
- Completely free.
- More options available for burning ISO image.
Cons:
- Take much more time.
- USB not bootable.
Part 4: How to Burn DMG to USB on Windows 10/8/7
If you're on a Windows PC, another way to burn a DMG file to a USB drive is to use TransMac. This is very useful if your Mac has become unbootable and you only have a Windows alternative. In such cases, you can use TransMac to burn the DMG file for Mac OS X (whatever version you want to install on your broken Mac) to a USB drive and do the installation that way.
To install Mac OS X, you're going to need a USB with at least 16 GB of free space. Also, it's better to take a backup of existing data so you don't lose it during the burn process. Follow the steps below to use TransMac:
Step 1: Download an original copy of TransMac to a Windows PC. The 14-day trial will let you execute the process we're going to describe, so go ahead and install it.
Step 2: Download the DMG file for the version of Mac OS X that you want to install. Now launch TransMac, but make sure to run it as the Administrator. Click on 'Run' once the application is launched, and insert the USB flash drive.
Step 3: The next step can be a little confusing because, normally, you would select the DMG or ISO file first before selecting the destination drive. Here, it's the other way around. In the main window, right-click on the USB drive in the left-side panel, then select 'Restore with Disk Image'.
Step 4: You'll get a warning popup. Select 'Yes' if you've backed up the contents of the USB drive, or else click 'No', backup the drive and then resume the process at Step 3.
Step 5: This is where you select the disk image, so go ahead and choose your Mac OS X .DMG file and click 'Ok'. The DMG file will now be burned to the drive you specified.
Pros:
- Make bootable USB installer from dmg image.
- Format disk to Mac compabile partition.
- Create new disk image.
Cons:
- Only 15 days of free trial.
- Costly price ($59).
Summary
All of these methods work well, so it's just a matter of preference and convenience, and depends on whether you have a Mac or a Windows PC. On a Mac, Disk Utility may show you some errors when burning a DMG file to a drive. Similarly, when you use a Windows system, converting DMG to ISO could corrupt the file, making it unusable once you convert it back to DMG. That's why we recommended YouConvertIt for that. Based on all these factors, choose the method that will work best for your specific situation.
Is there a way i can take my snow leopard user DVD, and make a bootable USB out of it on Windows. My friends mac doesnt have a DVD drive. I already was able to rip it into a DMG file. So how can i take that and make it a bootable USB? DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task.
Windows and Mac, they both are designed with different companies with a different file system. Because of their File system, it seems to us that we can’t create bootable USB for macOS Mojave on Windows. And the same goes for mac, where we are thinking we can’t create bootable USB for Windows 10 in mac. However, if you have used the Mac operating system, then you know that you can create bootable USB for Windows in mac with terminal and some other applications. But if you have used windows you will find out that you are not even able to create bootable USB for macOS Mojave using CMD or PowerShell. However, if we compare the Terminal and PowerShell, Terminal is built upon the Linux Codes and Infrastructure. but PowerShell is built by mixing all Unix, CMD, Scripts and other kinds of stuff. Jeffery Snover the founder of PowerShell said that anyone can work on PowerShell based on their platform. it means that if you are a Linux user you can use PowerShell, just like you are using the Linux terminal. This way PowerShell seems to be Powerful but yet no one has achieved to create bootable USB for macOS Mojave on Windows. I bet that for programmers it is not a hard thing but they are not interested in that. It is we, the basic users who wish to use a different operating system.
Dmg vitamin benefits. It should be noted that some kids tolerate DMG but not TMG.
So, enough of talk and let’s dive into creating bootable USB for macOS Mojave on Windows with TransMac, I hope it will be helpful for you.
Required Files:
- macOS Mojave Dmg File: In order to create bootable USB for macOS Mojave in windows 10, the first thing which is required is the macOS Mojave dmg File. If you have used a mac operating system, then you know that you can’t download macOS Mojave except for app store. I don’t know how, but programmers have decoded that from mac and uploaded the dmg file for windows users. Now windows user can download the macOS Mojave dmg file and they can use it to create bootable USB. And keep one more thing in your mind, if you visit any site download macOS Mojave iSO, then the flash won’t be bootable correctly. Because of those how are providing you the macOS Mojave ISO file, they have simply converted the macOS Mojave dmg file using PowerISO. Converting macOS Mojave dmg file to any other extensions requires a specific set of skills in the coding of an operating system. So, it is so rare that anyone put that much effort. However, I can’t predict if someone changes the macOS Mojave dmg to iSO in the future.
- 16 GB USB Flash: The macOS Mojave dmg file size is actually is 6.7 GB and at least it requires 8 GB of storage to extract the files. But since many users are facing errors, I would you recommend you to use a 16 GB USB Flash. And please make sure that the USB must be 3.0 because with USB 3.0 it takes 50 minutes to create bootable USB and I wonder How much time it would take for USB 2.0 to Create bootable USB.
- Transmac: TransMac is a software which is specifically built for windows users to mount, format, edit and create bootable for macOS. However there is also alternative software to TransMac but they are working best for Hackintosh file system (HFS), but since macOS high Sierra and macOS Mojave have Apple File system (APS), they can’t support it. Another thing which you must know about the TransMac, that TransMac is not free forever, it only provides you 15 days of trial. But After that, you have to purchase it.
Before creating bootable USB for macOS Mojave in windows 10 using TransMac, you have to download and Install TransMac. Installing TransMac is so simple and it does not require too much attention but in case if you don’t know How to Install. Follow the below procedures:
- Double click on the setup to launch the installation wizard.
- Click next, next, next, and next.
- Now click on the Install to copy the TransMac Files to your root drive.
- When the Installation is done, click Finish.
Step 1. Now Attach the USB Flash Drive to the Computer.
Step 2. Run TransMac as Administrator, if it is not given the full privileges it can’t create bootable USB for macOS Mojave.
Step 3. Right click on the USB and select format disk for mac.
Step 4. Once the disk is formatted for Mac, again right click and select Restore with Disk Image.
Step 5. Now the TransMac will warn that all files will be overwritten, so you have to click on the Yes and move to the next step.
Step 6. Now locate the macOS Mojave dmg file by clicking on the three dots.
Step 7. Once again it will warn you, that all the files will be overwritten, so you have to click yes.
Step 8. Have patients until the process of copying files should be complete, once it is done. Attach it to a computer and start installing macOS Mojave on PC.
Please keep in mind that the TransMac is only campable of creating a UEFI partition not legacy. If you are looing to create a legacy bootable USB Flash Drive you have to try using the Unibeast on Virtual Machine to create bootable USB.
Conclusion
That’s all with How to Create Bootable USB for macOS Mojave on Windows with TransMac? Well, if you have any question, suggestions, feedbacks please let us know.
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
Download WizDMG from the official website and install it on your PC. Launch the program and select the 'Burn' option in the main interface.
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.
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]
Make Bootable Usb From Dmg On Windows Transmac
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.
