Apple Dmg No Mountable File Systemsanfranciscotree



No mountable file systems dmg mac fix
  • Notarize a dmg 'no mountable file systems' Suddenly the notarization service failed with message: 'b'hdiutil: attach failed - no mountable file systems ', but I can mount the dmg in my mac. Until few days ago, notarization by same build process on CI works as expected.
  • When it does, it then adds an extended attribute of type com.apple.diskimages.fsck to the disk image file, and shouldn’t need to repeat it when you next mount that disk image. You can force macOS to bypass the fsck step using a command in Terminal of the form hdiutil attach filename.dmg -noautofsck.
  • I have a macintosh osx, my computer can't mount cds/dvds anymore (after about a minute or so it will spit them back out) I also cannot mount dmg files.
  • If it's different, try redownloading the file. If the md5 is the same, also try following steps 2, 5, and 6, if applicable, from the guide linked to in the first post. If all of that seems to be fine, see if you can open the dmg in safe mode.

Force-mount unmountable disk images | 16 comments | Create New Account

A DMG file is a proprietary disk image file format developed by Apple for its Macintosh line of computers. These are large, single files that comprise the entirety of a physical disk, such as a DVD or CD, and, just like a real disk, they can be damaged and made inaccessible.

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.

No Mountable File Systems Dmg Mac Fix

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.
