Fixing the error - no mountable file systems problem by Manual Method:

If you are facing Mac error no mountable file systems problem, follow these steps:

  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.
  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 into the terminal. 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

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.

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

AppleScript to Force-mount unmountable disk images

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..

Yeah, 'hdituil' is a typo.

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