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. Jan 24, 2019  iSumsoft BitLocker Reader for Mac is mainly to unlock BitLocker-encrypted drive on Mac, but it also comes with the Attach feature that can help you mount or unmount DMG files on Mac.

Great, Great, Great.
I am creating a lot of disk images at the moment for the distribution of a product and obviously I have to test those images. After mounting about 10 the Finder stops doing it's work as described in the hint. This problem exists even in 10.3.5 and I am very happy now, cause rebooting, the only solution I had figured out so far, really interrupts my work big time.
Thanks for the tip.

Rehab is for quitters!

I have an image that is password protected, and it still doesn't mount with this hint. Here's the output from terminal. Since the GUI password box came up on the display, I suspect that whatever OSX bug the command line evades is non-evaded when the PW function is called. Another encrypted image that mounts ok in the standard way (double-click) mounts fine using hdiutil. Haven't tried rebooting to see if that lets me mount the first image.
AppleScript to Force-mount unmountable disk images
It just so happens that we already built an AppleScript solution using this method; I'll paste it below for those who are Terminally challenged. As for the issue with password protected disks, this script will indeed trigger a GUI window asking for any such passwords not already stored in Keychain. I have yet to find an instance where presentation of the password box triggered the failure we're looking to overcome in this hing, but the -stdinpass switch would likely resolve it (see the man page), and could be added to this script. Sorry about the code wraps, Rob, I tried to install AS returns, but they wouldn't deal with the line wraps any better because of the parentheticals.

[Rob, you can delete the post above (when are we going to get edit privileges?) if you want; I modified the script to fit nicely--F]

Man, it is amazing how fast folks around here report bugs. Sorry for the oversights; the script was originally written for single DMGs, and I added multiples without really testing it or thinking it through; also we rarely use a special character in a file path because we're so used to working on the web. All bugs should be resolved, except those idiosyncracies that exist with name problems in hdiutil (such as 'image already specified' errors).

Now, if you could add an 'on open' handler that handled drag-and-drop, you'd be all set! Just drag your dmg files onto the script and they would mount. No file dialog to get in the way. :-)

AppleScript to Force-mount unmountable disk images

Hi there..
Well, I tried both versions of your script on several disk images (including one that I KNOW mounts fine by itself), and most of them were grayed out in my file dialog. My first thought was that perhaps they were corrupted, but at least one of them mounts fine on its own, and it was not accessible either.
I very much appreciate your scripting skills, but do you have any idea why I might be having such problems? Any suggestions from anyone else out there? I would really appreciate the help!
Thanks in advance,
mlaurenc

No Mountable File System Error

I may just be a big newbie, (and I undoubtably am), but when running this script the only items I could select when it asked me which DMG I wanted to mount were file folders and no DMG files. Even with a foler selected, 'Choose' never highlit. Am I doing something wrong?
Also, is there an applescript super newbie thread I should be hitting up before getting to knee deep in this?
by the way, rebooting still didn't allow me to mount the DMGs. I'm running 10.3.7.
Thanks for any/all help guys!

While this is a nice workaround - I really wish the problem would be solved instead. Very annoying. On my machine - happens everyday after about my tenth disk mount. The image actually appears to get mounted and appears in /Volumes but it shows up no where else and is impossible to access.

I must say, it doesn't happen much with me. But if it shows up in /Volumes, you should be able to refresh the finder by doing 'disktool -r'. I am writing a script that triggers mounting of dmg and the 'disktool -r' seems to solve some of my problem.
Good luck

I tried this Hint for the first time today, but I didn't appear to have the relevant utility. Typing in hd and tab brought up
hdiutil
which is not the command quoted in the actual command string in the Hint.
Anyway, I tried hdiutil, and it tried to attach the dmg, but failed with the same problem: no mountable file systems. <sigh>
Back to restarting..

iBook G3, 10.3.5, all updates current

Oct 18, 2014  Question: Q: Unable to install OS X Yosemite on my Mac. So, following the onscreen instruction, I selected 'Verify Disk' which then enabled 'Repair Disk' option. That failed so I got instructions to backu, reformat and then restore. All seems odd after not having any issues prior to downloading Yosemite! I'm now in the process of doing that. Jul 26, 2016  Strangely, the verifying process failed and multiplied itself nearly a dozen times, which unsurprisingly didn’t work at all. Nonetheless, running the.pkg file through the Installer app allowed the system update to install without a hitch. This is a fairly rare hiccup to occur with installations and updates, but I’ve seen it happen with Microsoft Office, VirtualBox, Mac OS X, and other downloaded. Verifying install mac os x.pkg installesd.dmg yosemite. To chose a different volume or partition to install Yosemite on, click this button, select the destination you’d like to use, and click on Install. In the window that appears enter your user.

Yeah, 'hdituil' is a typo.

Unfortunately, this didn't work for me. :-(

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:

Dmg Warning No Mountable File Systems Error

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):

I get the same failure, whether mounting from Finder or from Disk Utility.
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 --
