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.

Apple's Time Machine is the go-to backup method for many Mac users. Apple's termination of the AirPort series puts some users in a lurch over how they will be continuing to back up their Macs using Time Machine when Time Capsule is no more. Luckily there a few Apple approved Time Machine backup optionssans Time Capsule.

However, not everyone will be able or willing to use a spare Mac as a backup location or attach yet another external drive or even buy an expensive Time Machine capable NAS. There do exist other hacked solutions that will allow you to use any networked location — including a Windows share. Although this method cobbles together various utilities to make it function (and as such could be subject to points of failure), you can easily set up Time Machine to use a non-approved location for backups. Here's how!

Mac Dmg File

The problem

The issue that makes Time Machine more difficult in terms of options for backup locations is that it requires use of Apple's proprietary HFS+ filesystem. Although I'm certain the HFS+ features that Time Machine uses for file versioning and linking could be 'mimicked' for use on other more open filesystems, the reality is that Apple chose HFS+ and supports that filesystem exclusively in Time Machine (in fact as of this writing Apple's new APFS isn't even supported for Time Machine backups as of yet). How to decipher dmg and rpm in division 2.

Create a Windows share location

I won't go into detail on how to create a shared folder on a Windows PC but before you begin, you'll need to have a share created and accessible to your Mac that you want to run Time Machine on. For example, if you have a Windows PC named 'Server' and a network shared folder on the Windows PC named 'share', you'd be able to test for connectivity by doing the following:

  1. Start Finder.
  2. Click GO > Connect to Server.

  3. Enter smb://Server/Share where 'server' is the name of the Windows PC and 'share' is the name of the shared folder.

  4. Click Connect.

If you've properly set everything up, you'll be prompted to enter a registered user and password. Make certain to save those credentials to your keychain for the OS to automatically use those credentials for connecting to the share for future access. You should also see that share in Finder in your 'Shared' section and see the 'Eject' icon next to it since it is now mounted.

Create a sparsebundle image

We now need to create an 'image' file that will, in essence, pretend to be an HFS+ filesystem for your Mac to back up to.

  1. Start Disk Utility.
  2. Go to File > New Image > Blank Image.

  3. Rename the Save As to TimeMachine.

  4. Press the Down Arrow next to Save As.
  5. Select your mounted Share.
  6. Rename the Name of your sparsebundle.

  7. Select the Size of the backup location. Be generous. If you want to be able to at the very least backup the entire contents of a full hard drive, elect a size at least equal to your Macintosh HD drive size. As a word of warning, the size you choose will be the size of the disk space that will be immediately created on the remote share.

  8. Make certain that the Format is set to Mac OS Extended (Journaled).
  9. Click Save. This will take a while especially if you set a large file size.
  10. Click Done.

Make the remote share automatically mount

In order for this hack to survive reboots, we need to ensure that the remote share is automatically mounted when you restart your Mac. Here is a simple way to get this done. Some drawbacks of this method are that it only works once you've logged in and it won't work for other users of your Mac.

  1. Start System Preferences.
  2. Select Users & Groups.
  3. Select your Username.
  4. Click Login Items.

  5. Click the +.

  6. Navigate to and select your mounted share and TimeMachine.dmg file we created earlier.
  7. Click Add.

You may need to unmount the share before this can take effect but as of this moment, that share will automatically mount every time you reboot and log in.

Make Time Machine use the remote share and file

Finally, we're ready to make Time Machine see and use the Windows 10 share housing our sparsebundle file.

  1. Start Terminal.
  2. Enter the command sudo tmutil setdestination /Volumes/TimeMachine/ where 'TimeMachine' is the name you gave to your sparsebundle you created with Disk Utility.
  3. Enter your Password.

Check Time Machine

Now we just need to check that Time Machine sees the disk and is ready to use it for backups.

  1. Start System Preferences.
  2. Select Time Machine.

  3. You should now see that Time Machine has a backup location and Select Disk shows the proper name of the sparsebundle.

Final Comments

Yes, this is far and away from the simple 'just works' ideology that Apple is famous for. But if you have no other choice, it works for our Time Machine purposes. Do you have any comments or questions? Let us know in the comment section!
