How to Recover Deleted DMG Files on Mac
'Hi, I have accidentally deleted a couple of DMGs that I would like to get them back. I have dragged them to Trash and emptied the Trash. It seems impossible to restore the DMG files. What can I do to retrieve the lost DMG files?'
Apple Disk Images are files (usually with the .DMG extension) which the Mac OS X operating system uses to store disk images, with optional data compression and encryption. Such images can be mounted as volumes to access stored data directly from the operating system. DMG files are mostly used for software distribution over the Internet, but Mac OS X users can create images of their own disks.
While data loss happens every, DMG files are no exception. And sometimes data recovery from such images is required. This brief article explains how to use Mac data recovery software for this task.

How to Fix the Corrupted DMG Files
What if the DMG files are corrupted? How to fix them? Unfortunately, when the corruption happens there may be little you can do to reverse it. However, there are a few things you can try.
Step One: Back up
Before trying to fix a corrupt disk image, make a copy of it. While you may be able to fix a damaged image, it is also possible that these suggestions may further corrupt it, so be sure to work from a copy.
Step Two: Use Disk Utility
Disk Utility has several routines you can use to try to clear the problem. Open the program and drag the disk image copy into the devices list. Then select it and in the 'First Aid' tab run a disk verification. If any problems are found, try repairing the image.
If the problem still exists, you can try resizing the image. For resizing, you might try the options for resizing just the partition, just the image, or both the image and partition since these will target different parts of the image structure.
Step Three: Mount the Images
Sometimes the problem is with the disk image mounter not being able to handle the image structure. You might try mounting the image when booted into Safe Mode (holding Shift at start-up). You can also try mounting the image in another operating system. Many times the utilities built to enable Mac compatibility in Linux and Windows use methods for mounting or converting a filesystem that may be more successful at getting a filesystem mounted than the ones Apple provides.
Conclusion
To avoid DMG or other Mac data loss, you should do the following things:
- Enable Time Machine Backup feature or data protection on Mac computer
- Never use RM Command or command terminal to delete a file
- Check selected files carefully before pressing Delete option

Then i click onto the restore tab making sure the .DMG is in the source field.
I then drag the flash drive name from the sidebar into the destination field.
I then click restore it then asks for admin password then the .DMG password after that it starts to scan the disk image bt then fails with the.

Nov 16, 2018 Method 2: How to Convert DMG to ISO on macOS (Disk Utility) Mac OS X and macOS offer an easier way to convert DMG to ISO, which is only natural because DMG is the native disk image format used by Apple. The Disk Utility that's built into Mac will help you do the conversion from DMG to ISO. Follow the steps below to convert your disk image files. Convert dmg to bootable iso mac. Convert DMG to ISO and Create macOS Boot USB from Windows. Since ISO is a better format for Windows, you can also convert the DMG to the ISO format and then use the ISO disk image to create the bootable USB. Please note that you can't boot your Mac from bootable USB made from an ISO file, which means you'll have to convert it back to DMG prior. Convert DMG to ISO options. When trying to convert a DMG to a ISO or CDR file for MacOS X, we have two options available. The first one is by using just Disk Utility, a preferred method if you don’t like working with Terminal. The second method is by using the command line by using Terminal. 2) DO use “tools/convert” to open DMG 3). Then, simply hit the convert button. Browse to your destination folder (Default is the same one your dmg is in) and u will find a perfectly converted ISo file. Hope this helps. UltraIso is also great for “all things ISO, like opening, updating and creating bootable burned ISO.
I have tried the terminal command
sudo asr –noverify –source '.DMG' –target ‘/Volumes/UNTITLED 1′ -erase
This also comes back with an invalid argument.
Not sure what i can do now as i cant seem to be able to do it with disk utility are there any 3rd part apps which could use to do this?
