How to open Apple's DMG files in Windows 10. By Roger Fingas Friday, June 07, 2019, 08:45 am PT (11:45 am ET) One of the potentially frustrating things about switching back and forth between Mac. Aug 21, 2012 I opened a DMG file when I needed to install chrome and there were no issues with that. Now I'm trying to install the VPN with the DMG file but it doesn't open. All that happens is that I click on the DMG file, and then it doesn't respond. I'll go to my downloads folder in the doc and it won't do anything. Is it just that.dmg that won’t open? Have you tried a different one to compare? Basically there’s no reason that should be happening. So unless it’s happening with.
Open Kmg File
- The installer DMG file did not fully download, the download was interrupted, or otherwise damaged. Download again and wait for the download to complete before opening the DMG file. If the problem persists, the network connection may not be reliable enough for a large download.
- DMG file provides some attractive features that allow securing password along with file compression. These virtual or physical Apple disks can be cloned from one to another. This is one of the powerful features of Mac. Tip: If you want to open and view DMG files of Apple Mac OS X so, you can try DMG Viewer tool. Why DMG Files Are Created?

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:
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 urlin Terminal to download the file. (There's an example of that in my screenshot below.)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.
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 -verboseinto 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.
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_APFSor error112, 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 -verboseoutput that shows an APFS error due to an older version of macOS: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.
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.
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.
If you are an avid Mac user using a Windows PC, and suddenly find a DMG file in your windows system, you would definitely want to open it up to see what it contains. Though the installation files or compressed files it contains will not be compatible with your windows PC, yet there are some ways you can check out what it withholds. But before proceeding with the ways to open or view a DMG file, it is better if we have a thorough knowledge of what a DMG file exactly is. DMG files are actually Mac OS disk image files. It is very similar to ISO files in windows, or rather a counterpart of ISO files.
The images usually comprise installation files of softwares and operating systems and sometimes, compressed files. Since you are using a windows PC, surely you won't be able to run it on your Window OS, but at least there are ways by which you can have a look at its contents. And that is what we are going to discuss in this article - ways to view the DMG files on Windows 10/7/8.
Way #1: Open DMG Files on Windows with 7-ZIP
7-ZIP is a lightweight freeware which is easily available on the internet market. It not only extracts DMG files but all other of compressed files, such as ZIP, CAB, ISO, RAR, WIM, etc. But we would restrict our discussion here only upto DMG. Read the steps below to know the tool's usage:
Step 1. Download the 7-ZIP program file in any of your working computer and install it.
Step 2. After installation is done, locate the DMG file that you wish to open or view in your directory or desktop, and right-click on it.
Dmg File Won't Open In Mac Drive
Step 3. From the context menu, click on '7-ZIP' which will not appear as a part of your system since installed.
Step 4. From the next sub-menu that follows click on 'Open archive' and your DMG file will be opened and you can view the contents inside.
Cons:
- You cannot view or extract files bigger than 4 GB.
- You cannot view or extract encrypted files.
- You are only allowed to extract 5 DMG files at a time.
Way #2: Open DMG Files with DMG Extractor
DMG Extractor is another professional tool to open and extract .dmg files without first converting them into .iso or .img files. It's interface is very user-friendly and even a beginner can use it without any difficulty. Just go through the steps below to pull off the task:
Step 1. First of all, download the DMG extractor program file from the internet and install it in your personal Windows PC.
Step 2. Run the application with admin rights and in the main UI of the tool's screen, click on 'open' button in the upper menu bar to browse the required DMG file. The file will be loaded into the software's screen.
Step 3. After the file is loaded, you will be displayed all the contents contained within the DMG file.
Cons:
- You cannot view or extract files bigger than 4 GB.
- You cannot view or extract encrypted files.
- You are only allowed to extract 5 DMG files at a time.
Way #3: View DMG files on Windows with PowerISO
PowerISO is yet another very powerful professional tool which can open, burn, extract, create, edit, convert, any kind of disk image files. It can process every kind of image files, be it BIN, DMG, ISO, DAA, etc. Here we would burn the image file into a CD/DVD or USB and then will open it from the disk storage to check out what it contains. But before you head on the tool's usage, better have a look at its specifications to use it in a better way.
Step 1. Get the program file downloaded from the official website and install it in your Windows computer.
Step 2. Launch the utility with admin privileges and then insert a empty Disk (CD/DVD or USB) in your computer.
Step 3. Click on 'Tools' button from the menu bar and then click on 'Burn' option from the drop-down menu.
Step 4. Now the 'DMG Burner' option will be shown in the PowerISO Window's screen.
Step 5. Click on 'Browse' button to fetch the required DMG files from your computer's directory.
Step 6. Select the burning speed from the dialog box and then finally click on 'Burn' button to start the burning process.
Step 7. Once the image is burnt in your disk, open the disk from 'My computer' and click on the DMG file to view what it contains.
Conclusion:
After going through all the methods mentioned above, you must have realized by now that the first two tools implemented have got several demerits and thus can be not relied upon fully. So in order to have all the facilities with disk images, better stick to way 3 for a guarantee result.
