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.

This guide covers the verbatim copying of a DMG image to a USB thumb drive using only Linux (no need to find a Mac). If the DMG was intended to be bootable then the resulting USB will be bootable. Convert to ISO. Linux doesn’t much care for DMG files. Sure, it’ll play nice with them. But we don’t just want to play nice. To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps. To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps. Dec 20, 2009 Transmac for Windows (2-week trial) can format USB drives for mac and restore.dmg files to USB drives. Download Transmac and install in Windows. In the right-side panel of Transmac, right click on your USB Drive Format Disk Format with Disk Image (see attached screenshot) Point to your.dmg file and click Open.
While DMG files are usually downloaded from the Mac App Store, they can also be burned to a USB disk when you want to install a utility on another machine. In such cases, you will need to create a boot disk or burn it to a USB flash drive so it can be used on another system. This article shows you four different ways to do this.
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 : Next, 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.
Part 2: How to Burn DMG to USB (Bootable) via DMG Editor on Mac
UUByte DMG Editor is a versatile application that can help you burn converted DMG files to a USB drive. The interface is very simple, and all you need to do is click a few times and the job is done for you. DMG Editor gives you the option of creating boot disks or boot drives, and is the perfect tool for transporting your DMG files in their ISO avatar. Assuming you have a USB drive with enough capacity, it can hold several programs.
DMG Editor doesn't require any technical expertise because it is specifically designed for new users who may not be comfortable handling disk images. All the hard work is done behind the scenes, and the layout is intuitive enough for any novice to figure out what to do. For first-time users, here's a small guide for using it to get a converted ISO file burned to a USB drive.
Key Features of DMG Editor
- Make USB bootable after burning to USB.
- Able to edit DMG file and recreate it.
- Also support burning to CD or DVD disc.
- Easily extract files from DMG file.
Step 1: Install UUByte DMG Editor
Install DMG Editor after downloading it from the official site. Insert your USB drive into a free port.
Step 2: Insert USB Drive and Import DMG File
Launch DMG Editor and select the 'Burn' option, which will take you to a new window.
Step 3: Start Burning DMG to USB
Select the DMG file and specify the destination, which is your USB drive. Click on Burn. That's it! In a few moments your USB drive containing the converted DMG file will be ready. You can now use this to install the program or programs to another Mac computer after converting them back to the DMG format.
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.

Part 4: How to Burn DMG to USB on Windows 10/8/7 (TransMac)
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.
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.

The capacity of your external flash drive or SD card is large: 8GB, 16GB, or more. There is enough free space on the drive. You can copy the smaller files to the external drive just fine. Yet, when you attempt to copy a large file (4GB or larger) to the external drive, Windows gives you an error (such as: There is not enough free space on the drive, or similar.) Does this sound familiar?
If you experience such a problem, most probably it’s caused by the fact that your external drive or card is formatted with the FAT32 file system. This type of a file system has a built-in limitation on the size of the files that it may contain. Although the total size of the files that you can copy to a FAT32 drive could be as large as 2TB (or the physical capacity of the drive, whichever is smaller), the size of each individual file may not exceed 4GB.
This limitation may sound silly: why would anyone design a system that would not allow for the larger files? The problem is, when the FAT32 file system was designed (that was back in the days of Windows 95), no one anticipated that we would have such large files in use today. Or, maybe the designers hoped that by the time such large files become common, the use of the FAT32 system would be replaced by the more modern systems.
In any case, how to solve the problem of copying the 4GB files? Easy: you need to replace the FAT32 file system on the drive with a more modern one, such as NTFS or exFAT. These newer file systems do not have the 4GB file size limitation! Scroll down this page for the instructions on how to change the file system.
Which file system is better, NTFS or exFAT?
They both are pretty good, but which one to choose depends on how else you are going to use the external drive or SD card.
The NTFS file system is supported by all modern versions of Windows (including such dinosaurs as Windows XP, Windows 2000, and Windows NT), and it also supports many other functions not supported by FAT32: file security, encryption, compression, etc. However, if you plan to use the external drive with non-Windows devices (such as an Android tablet or a Mac computer), it would not be recognized by such devices out of the box, and you would need to install additional software or tweak their settings quite a bit to make them work with the NTFS drives.
The exFAT system is not as advanced as NTFS (it does not support the file permissions and access control, for example), but it has more support on the non-Windows platforms. For example, many Android phones and tablets, as well as the recent versions of macOS support exFAT devices pretty well.
How to change the drive from FAT32 to NTFS or exFAT format?
Let’s show how to do it for NTFS first:

1. Attach the external flash drive to the computer, wait for Windows to recognize it and assign a new drive letter to it.
2. Open the Computer folder and locate the drive letter assigned to the flash drive you want to format with NTFS (in the example below, it’s drive F:)
3. Before continuing, open the drive in a window and make sure it’s empty or does not contain any important files, because after you format a drive, all information that was on it will be erased! If there are files on the drive that you want to keep, take this opportunity to copy them over to the hard drive or some other drive.
4. If you are sure that the external drive contains no important files of yours, go back to the Computer folder, and right click on the icon of the external drive:
5. Select Format from the menu, and then choose the formatting options:
6. Make sure to select NTFS in the File System drop-down list. That’s what determines the kind of a file system that the drive should have. Also, you may want to select the Quick Format option, which should speed up the formatting process quite considerably.
7. Press Start, and Windows should warn you once again about erasing any existing information on the drive (see step 3 above). Again, if you are sure the drive does not contain any irreplaceable documents, confirm that you want to proceed with the formatting:
8. If you’ve selected the Quick format option, the formatting should take no longer than a minute or two.
As a result, you should have the same drive, but now it should have the NTFS files system on it. Now you should be able to copy the files larger than 4GB to the drive just fine.
In addition to formatting a drive with the NTFS file system, Windows also offers a way to convert a FAT32 drive to NTFS. The difference is that the conversion process would keep the existing files on the drive. See Windows Help and Support of your computer for the instructions on how to do the conversion.
What if I want to use exFAT instead of NTFS?
The steps to change to exFAT are the same as for NTFS, you only need to select exFAT in the dropdown box instead of NTFS.

P.S. Our encryption software USBCrypt can create a NTFS- or exFAT-formatted Virtual Encrypted Disk even if the host drive is formatted with FAT32. This suggests yet another solution: instead of formatting the host disk with NTFS, you can instead use USBCrypt to create a NTFS-formatted Virtual Encrypted Disk. If you do that, then in addition to breaking the 4GB file size barrier, you would also get the strong security and password protection for files you put inside of the Virtual Encrypted Disk. See the USBCrypt web page for more information or to download a free 30-day trial.

P.P.S. If you only need to transfer a large file from one computer to another, you can get by with the FAT format if you use a file splitter utility, like the one included in our file manager AB Commander. Using its Split command, you can split a large file into smaller chunks (say, 2GB each). Such chunks can be put on a FAT-formatted drive without a problem. Then, on the destination computer, use the Merge command to combine the chunks together into the original file. Of course, if you want to open the file directly from the external FAT drive, this won’t help you, but just to transfer the file between Windows computers should work fine.
P.P.P.S. Here is what to do if Windows does not offer the NTFS format option.
