No Mountable File System Dmg Problem

  • Hello All: Thanks much for your help - I was able to mount the my remote control.dmg file with Disk Utility, loaded my remote control app, cleaned up his disk permissions and loaded the printer driver software that was the original problem.
  • Jul 20, 2013  I'm trying to download Office for Home & Student 2011 to my new Macbook. The download gets to 940MB of the 1.04GB. Then I get a message which reads The following disk images couldn't be opened. Image: X18-08827.dmg. Reason: no mountable file systems. In layman's terms, what does this mean and what should I do to fix it?
  • How To Fix DMG No Mountable File Systems In Mac System. The Mac OS is greatly used across the world, this is because of its reliable features, and best management, security and accessibility. One thing you should know that the data in Mac are kept secure by building a DMG file that stands for Disk Mounted Graphics.

Using QT 5.9.2 & QTCreator I compiled in release mode today (XCode-Clang 64bit) then ran 'macdeployqt' from the command line to produce a *.dmg. It opened and ran fine on another OSX Sierra machine. However two 'El Capitan' computers can not mount the .dmg. During the 'verifying' process an error is thrown: 'No Mountable File Systems'.

Mar 26, 2017  Are you having problem installing Applications on your Mac running on Mac Seirra Operating System? Have you got a warning message that No mountable file systems.

I have a wrapper script to run 'macdeployqt' so I know the dmg and zip are being packaged exactly as they have been for months. This worked just fine the week before Christmas. My computer updated to Mac OS High Sierra 10.13.2 last Friday January 5th.

How to convert iso to dmg using magiciso. Are there any known new backwards-compatibility issues running 'macdeployqt' on High Sierra possibly causing the files to fail on El Capitan (10.11.6)? Has anyone else experienced this or can someone else please try to recreate it?

Mountable

I'm trying to do a complete backup of my wife's MB from my MBP. I booted the MB into Firewire Target Disk Mode, then used Disk Utility on my MBP to make a DMG of it onto another external FW drive. Here's the log from Disk Util:

When I tried to mount the image, it went through a 20 minute verification procedure, then failed with the 'no mountable file systems' error.
I tried mounting it from Finder by double-clicking the DMG and got the same error. So I deleted the DMG and re-created it from scratch (including rebooting the MB into TDM):

WTF? Does anyone know what might be going on? I came > < this close to repartitioning her HDD, then I got the willies and decided to verify the image first. Good thing I'm paranoid, otherwise my wife would have had a factory-fresh MB right about now. -- View image here: https://cdn.arstechnica.net/forum/smilies/scared_classic.gif --
