DMG file is a Disk Image format, which was introduced by the Apple. This file is the proprietary disk image file used on Mac Operating System machines, which store disk images followed, by optional encryption and compression. Many users tend to use this file to save important data and hence its analysis and forensics can bring out many hidden evidences. This file is important from Apple machine’s digital scrutiny point of view and it holds chances of reaching to the helpful evidence. These images can also be mounted as volumes in order to access the data from the current OS directly.

Challenges to Open Corrupt DMG File

• Compressed or encrypted DMG files are usually not supported by the file examination applications, as they are read-only files.
• Unallocated space is not available in the compressed DMG file and hence the analysis can be difficult for such files.
• Moreover, encrypted files are not supported by most of the 3^rd party tools and hence it can be cumbersome for investigators to deal with the encrypted files.
• Most of the investigators’ workstations comprise of better and more convenient Operating Systems and hence they use Windows. However, DMG file is not supported on Windows and hence investigators can find it difficult for investigating these files.
• Deleted data can hold important evidence and hence it is important to recover data from corrupted DMG file for further analysis.

In order to resolve all challenges, it is important to take help from a third party software program like DMG Viewer to open corrupt DMG file. This utility is a Windows based utility, which support Apple DMG file format and help to open and view the DMG file on Windows machine.

This is a freeware application and supports all the Windows versions. Software supports recovery and viewing of permanently deleted files from DMG image disk file. It also supports compressed or encrypted DMG files aiding forensics investigation on it.

One of the major differences between Windows and macOS is the way they read, write, and install files and applications. For example, Windows uses .exe files to execute programs while macOS uses a .pkg file to install an app or a .dmg file to clone existing drives. Some app installers also come in DMG format and the Mac user just needs to mount the file to extract the installer and run the package.

Apparently, if there are too many dmg files open, the no mountable file system Mac error is caused. Disable if you have enabled any restrictions that need permissions or prevents accessibility to external drives (thumb drives, optical drives, etc.). Try mounting the disk image file in the command line in Terminal. Open a Mac app from an unidentified developer. If you try to open an app that isn’t registered with Apple by an identified developer, you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began.

But for some reason, several Mac users have been experiencing issues with DMG files. For example, one user posted on Apple’s support website about his Mac not being able to recognize the DMG files he created as a backup. The user had to do a clean install of the entire operating system, so he saved the important data in a DMG format. Unfortunately, once his Mac was back up and running again, the DMG files he created were not recognized by the freshly installed operating system.

Other Mac users encountered the error when downloading files from the internet, such as app installers or software updates. The files seemed to be downloaded successfully, but when they try to mount the DMG file, they get a notification that the disk image can’t be opened because macOS can’t recognize the file. There are also instances when macOS says that the DMG file can’t be mounted because it is still being downloaded, but the file has been downloaded completely on the device.

This error can be quite irritating if you want to install a specific app on your Mac and the downloaded installer from the internet is not recognized by macOS. What’s even more frustrating is when the DMG files you want to mount are your backup files from your previous macOS installation and they contain important data and files.

If you are getting this error when opening your DMG files, this guide will be quite helpful for you to resolve this error and successfully run your problematic DMG files.

What is a DMG File?

Before discussing the error, let us first understand what a DMG file is and what it is used for. DMG is a file format that you usually encounter when using a Mac. A DMG file, also known as Apple Disk Image or macOS Disk Image file, is a digital reconstruction of your physical hard drive. It is the macOS version of Windows’ ISO files. If you’ve worked with Windows before, then you have a pretty good understanding of what an ISO file is. A DMG file works the same way as ISO files.

Just like ISO files, the DMG file format is often used to save compressed app installers instead of using physical disks. You’ll notice that most macOS software that is downloaded from the internet is in this format. The Apple Disk Image supports file compression, file spanning, and encryption. So don’t be afraid when you are asked for a password when you try to run a DMG file.

DMG files are available only for Macs that run OS X 9 and later versions. Download java runtime environment for mac 10.10 full. For those with older Macs, the IMG file format is used instead.

DMG files were created for macOS, so opening or running it on a Mac should be very simple. When you copy the DMG file or you connect the drive where the DMG file is saved, it is automatically mounted by macOS as a drive and is treated as an actual hard drive.

DMG File Not Recognized Error on Mac

Launching a DMG file should be a straightforward process, but that’s not the case for everyone. For some reason, some Mac users are getting the “DMG file not recognized” notification whenever they try to mount their files. An error window that lists down the problematic files pops up, along with the following error message:

The following disk images couldn’t be opened.

Reason: not recognized.

Because of this, users are not able to access their files or install the software in the DMG file. This error can be caused by several different factors, so users need to investigate closely to find out what went wrong.

One possible reason why macOS can’t recognize your DMG file is because it is corrupted. If you downloaded the file from the internet, it could be that the file itself is corrupted or something happened when you were downloading the file.

If you created the file as a backup from your existing files, it is possible that something went wrong during the conversion process. An outdated operating system can also cause your file system to not function properly, leading to errors such as this.

So what do you do when you get this error?

How to Fix the ‘DMG File Not Recognized’ Error

It can be frustrating when you get this error, especially if the DMG file contains your backup files and you can’t seem to retrieve them. When you get the “DMG file not recognized” error on Mac, you need to consider various factors to determine the cause of the problem. From there, you can easily fix the problem by referring to our guide below.

Step 1: Check Your Internet Connection.

When you download the DMG files from the internet, make sure that your internet connection is stable and strong. Switch to wired connection if possible. An incompletely downloaded DMG file will not run because of the missing components.When your download gets interrupted because of power interruption or poor internet connection, the file is not successfully downloaded, causing errors at the end.

Step 2: Download From Official Sources Only.

If you’re downloading an app, get the installer from official websites only or the Mac App Store. When you download from somewhere, you have no idea whether the app is fake or is bundled with malware. To make sure you’re downloading a clean and complete DMG file, get it from official sources only.

Step 3: Clear Out the Junk Files.

When you have too many unnecessary files on your Mac, the system gets cluttered and file system errors appear. Clean up your files and optimize your Mac using Outbyte MacRepair. Make it a habit to perform regular maintenance tasks to avoid future errors. Sinatica monitor for firebird.

Step 4: Try to Open the File on Another Mac.

It is possible that the error has something to do with your Mac, so you might need to try it on a different Mac to rule this factor out. If the DMG file is successfully mounted on a different computer, then you can be sure that there is no problem with your file. What you need to figure out next is why your computer can’t recognize it.

The converse is also true: if the file doesn’t open on another Mac, then the file itself is the problem. If this is the case, redownload the file from another source and see if this makes any difference.

Step 5: Mount the DMG File Using DiskImageMounter.

The DiskImageMounter is the default app designed to automatically open DMG files. If you’re having problems mounting the DMG file, you can do it manually using the instructions below:

1. Right-click on the file, then choose Get Info.
2. In the Get Info window, scroll down to the Open with: section.
3. Click on Open with: and choose DiskImageMounter from the pop-up menu.
4. If you don’t see DiskImageMounter listed among the options in the pop-up menu, select Other instead.
5. When the Finder window appears, go to /System/Library/CoreServices/.
6. Locate the DiskImageMounter and click on it.
7. Click on the Change All button.
8. Click the Continue button when you see the confirmation message.

You should now be able to mount your DMG file using DiskImageMounter.

Step 6: Open the File Using Disk Utility.

When you can’t open the DMG file using ordinary means, another option is to use Disk Utility to open it and save the contents using a different format. To do this, follow the steps below:

1. Open Disk Utility by going to Finder > Go > Utilities.
2. Click on the DMG file you want to open from the list of drives on the left.
3. Click on 7-Zip or DMG Extractor to at the upper left portion of the window.
4. Rename the file to differentiate the old from the new version. For example, sample becomes samplenew.
5. Click on Save and wait for the file to be converted.

Once the process has been completed, you will now be able to open the contents of the DMG file.

Step 7: Extract the Content of the DMG File Using a Third-Party App.

If you can’t mount the DMG file on your Mac in the first place, you can’t use Disk Utility to open it. Your last option would be to use a third-party extractor to get access to the files. You can use 7-Zip or DMG Extractor to open the DMG file. Just install the app, right-click on the DMG file you’re having trouble with, extract the files and save them to a folder you can easily access.

Summary

DMG files are great for installing apps on Mac and for creating backup images of your files. Its encryption and compression functions also make it a lot more secure compared to other file formats. However, it can also be troublesome when macOS fails to recognize the file because you can’t open it or access the contents. If this happens to you, don’t worry because you have several options. You can try any or all of the steps above to successfully mount your DMG file.

I ran into an interesting macOS error while working with a customer a couple of weeks ago. I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself.

The error was as the screenshot above shows; trying to open a dmg (disk image), macOS showed the error 'no mountable file systems'. If you see the 'no mountable file systems error' while opening a dmg, here's what you should try:

1. In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. (There's an example of that in my screenshot below.)

2. Reboot your Mac if you haven't already tried that. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot.

3. Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:

   • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

   • Type hdiutil attach -verbose into the terminal. Add a space at the end, but don't press enter yet.

   • Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.

   • Press enter.

4. macOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to Apple_APFS or error 112, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.

   Here's an example of the end of hdiutil attach -verbose output that shows an APFS error due to an older version of macOS:

5. Think about if you have any kind of security policies on this machine to prevent writing to external drives (thumb drives, optical drives, etc). I haven't seen this one in action, but I read about this being a possibility while researching the issue.

6. Another suggestion added by a reader (thank you, Markus!) is that filesystem errors on your main Mac drive could be the cause of the disk image mounting errors. Here are instructions from Apple for scanning and repairing errors using Disk Utility. Note that in order to scan and repair errors on your main Macintosh HD drive, you'll need to reboot your Mac into recovery mode. You'll want to choose Disk Utility in the utilities listed in the recovery mode menu.

7. A new discovery from a reader (thank you, Colby!) is that APFS DMGs won't mount if you're booted in macOS booted in Safe Mode. (Who knew!?!) If you're not sure if you're in safe mode, select the Apple menu  > About This Mac > System Report button, then select the 'Software' heading from the left column. To exit safe mode, restart your Mac, without holding Shift during startup. Or, if you previously set your Mac to always boot into safe mode using nvram, turn off safe mode and have your Mac boot normally on the terminal:

   • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

   • Type/paste sudo nvram boot-args=' and press enter.

   • Restart your Mac.
