In this blog, we will share two different methods to create a disk image—the first one using macOS Mojave’s Disk Utility and the second using a Mac data recovery application. Read on to know the benefits of one method over the other.

How to Open a DMG File in Windows Martin Hendrikx Updated April 2, 2018, 10:29pm EDT Whether you are an avid Mac programmer using a Windows PC, or you just found a DMG file on your Windows machine, it can be useful to know what it is and how to open it.
Disk image of an external or an inbuilt Mac storage drive is immensely helpful in recovering files in case the source drive fails or dies. You can create a disk image of your APFS or HFS drive on a larger storage medium and access it at a later point of time.
Create a Disk Image Using Disk Utility on macOS Mojave
macOS Mojave’s inbuilt Disk Utility provides an option to select a mounted storage drive be it internal or external SSD/HDD and create a disk image (.DMG) file to a location other than the source disk. The systematic steps to create a disk image of a drive using Disk Utility are as follows:
- Open DiskUtility and select the storage drive from the sidebar
- Go to File > New Image > Image from “DriveName”
- Give a name to your disk image file and provide a destination to save the file
- Click the Format popup menu, then choose your required option
- If you want to limit the access of this disk image file, then click the Encryption popup menu to set a password for its access
- Click Save to continue the imaging process
- Click Done once the imaging process is over
Disk Utility mounts the image file’s disk icon on the desktop and sidebar of Finder. You can use the mounted image file to open its content.
Create a Disk Image Using a Mac Data Recovery Utility on macOS Mojave
The third-party data recovery utility, Stellar Data Recovery Professional for Mac also allows you to create a disk image (.DMG) file of the inbuilt Mac storage drive/volume or an external storage device. The logical steps to create a disk image of a drive using the utility are as follows:
Step 1)Download and install Stellar Data Recovery Professional on your Mac with installed macOS Mojave (or later macOS/OSX)
Step 2) Launch the software and select RecoverData from the main interface
Step 3) Click the ‘2nd‘ icon present at the top of the interface and select CreateImage
Step 4) From the “CreateImage” screen, select a drive or a volume to create an image file
Step 5) If you wish to create an image of the entire selected storage location, click Next
Step 6) If you wish to select the range to create an image, click the AdvancedSettings
- From the “SelectRangetoCreateImage” screen, drag the sliders to define the starting and ending sectors of the image file
- Click Close and then click Next
Step 7) In the “CreatingMediaImagetoSave” dialog box, locate the destination where you wish to save the image file
Step 8) In the “SaveAs” text box, type the disk image name and then click Save
This completes the disk imaging process using the software. Unlike Disk Utility, macOS Mojave does not mount this image file for you to access its data. Nevertheless, you can keep this newly created disk image as a backup and use it to recover data at the time of data loss.

Recover Data from a Disk Image Using the Software
The methodical steps to use the .DMG file for data recovery are as follows:

Step 2) Click the ‘2nd’ icon present at the top of the interface and select Load Image
Step 3) From the “Load Image” screen, select the .DMG file or else click Add to add the image file
Step 4) Click Scan to start the recovery process
Step 5) Once the scan is over, preview and select the required files then click Recover

Conclusion
We hope the blog helped you in understanding the practical details of how you can create a disk image file of a storage drive on macOS Mojave. By implementing Disk Utility, you can generate a disk image file and can open the automatically mounted image file from the saved location. On the contrary, by using Stellar Data Recovery Professional for Mac, you create a disk image file and use it to scan and recover lost, deleted, or inaccessible files.
Unlike Disk Utility, the software allows you to select the specific region of the drive for image creation. We recommend this method to recover files from a storage drive that is too big in size. For instance, if your storage drive has the data storage capacity of say 8 TB, then you need to recover data in portions. Ubuntu create bootable dmg for mac. Free download the software to create an image, scan, and preview files. Register the software to save the recoverable files.
Files in .dmg format are easier for Mac users to download and install than other file formats. This document describes how to convert a file saved on a CD or DVD into a .dmg file, and how to burn the .dmg file onto another CD/DVD.

Make a mac boot dvd on windows dmg download. But you say it won't be bootable.well I think we need to use a boot loader no?Ehhhh. Have 2 dvd's left to try)and once I had the DVD, to install it on vmware after booting it with the snowy vmware files.
- Double-click on Disk Utility to open the application.

- Click on the File menu at the top of the screen. From the drop-down menu, click New, then Disk Image From [name of your disk].
- Type a name for your new file, then navigate to the Desktop to save the file there.
- Under Image Format, choose compressed.
- Click Save. You now have a .dmg file saved on your desktop. Next, you can burn the file onto a blank CD/DVD.
Burning the DMG file
- Eject the original CD/DVD from the computer and insert a blank one. If you are prompted with a pop-up window, click Ignore.
- Return to Disk Utility, and click the Burn button at the top of the window.
- Navigate to the Desktop, and highlight the .dmg file you saved. Click Burn.
- Click Burn again in the new window to accept default settings.
- Once the program finishes burning the disk, it will automatically eject. You should now have a burned CD or DVD with a copy of the original file saved in .dmg format.
