Encrypted dmg won't mount

Not sure where best to post this - admins -- if desired please feel free to move.
I created an encrypted .dmg file in disk utility to secure a small amount of info. I did a time machine backup of my machine, then did a clean install of OS X (getting ready to sell my mbp) and later tried to access the dmg on the time machine external drive. When I try to open the .dmg I am prompted for the password (this is NOT a forgotten password issue) and then I get the following error, "The following disk images couldn't be opened....no mountable filesystems"
I also did some searching on this and tried to do command line "hdiutil attach", and get the same no mountable file systems error.
I also tried entering the password and saving to keychain, but no results.
any help appreciated, extremely important info on this disk, thanks.....

Solved my own question with some more searching - the solution that worked for me is described here - step by step:
http://digital.ni.com/public.nsf/allkb/52C5671CD2608532862575ED0001F1EC
and in case that link ever gets broken here's the copied text:
Open Terminal.app (Macintosh HD/Applications/Utilities/Terminal.app)
Once the terminal opens, type 'cd' without quotes.
Navigate to the folder that contains the .dmg file. In this article the .dmg file is located on the desktop and is called LabVIEW.dmg
Click on LabVIEW.dmg once and hold the mouse button down.
Drag the mouse into the Terminal window, and then release the mouse button. This will add a static link after the 'cd' command we typed earlier. You should see something similar to this:
Delete the actual file name (in this case LabVIEW.dmg) so that only the file's folder path remains:
Press the Enter key.
Type 'hdiutil attach LabVIEW.dmg -shadow' without quotes.
(replace LabVIEW.dmg with the name of the .dmg file you're trying to mount).
The Terminal will pause briefly and then mount the .dmg file.
National Instruments only recommends using this solution for .dmg files that are read-only. This is due to fact that a shadow image is created that contains any changes to the .dmg file. Since all National Instruments .dmg files are read only this method will work without issue in Mac OS X.

Encrypted .dmg won't mount after upgrade to Snow Leopard

Just upgraded to Snow Leopard and having trouble mounting an encrypted disk image that I use for my confidential files. I have tried mounting using both DiskImageMounter.app and the Disk Utility but both give error 60008, unable to attach.
Anyone else having similar problems or have suggestions for alternative ways of mounting?
Best,
Jon.

My encrypted disk image with confidential files was created under Leopard using Disk Utility. I just upgraded to Snow Leopard and when I try to mount the image, the password box comes up (as before the upgrade). But, I enter my password, and the disk image does not mount, it just keeps asking for the password again. I also have the latest MacBook Air and I also have an encrypted disk image there too with the same problem when I try to mount it. In addition, I have a LaCie 1TB External Harddrive that contains an encrypted disk image. When I try to mount this disk image, which normally appears on the desk top, I get the same repeating password box. Entering the password does nothing--other than causing the password box to reappear. All three encrypted disk images worked fine without any issues before the upgrade. So, based on the number of views that this post has had, this appears to be an issue that needs a resolution. Any suggestions or others with similar problems?

DMGs Won't Mount!

Hello,
I am downloading iTunes 6 for my PowerMac G4 Cube. The DMG file downloads fine. But it won't mount. When I double click on it to mount it, this comes up:
"The following disk images failed to mount
iTunes6.0_Mac_OSX.dmg - Reason: No mountable file systems.
I have deleted a couple of apps such as Chess, Image Capture and iMovie but I do not believe that this has any effect on this problem.
Thanks!

Hi, the DMG could be corrupted. When it's an extremely large file, sometimes missing a few packets makes the file broken. Have you tried redownloading it several times?
HTH,

Help! DMGs won't mount!

I'm not an incredibly computer literate person but the description below is what my computer guy at work emailed to some people, and they didn't know what to do. Anybody else have any ideas???
The problem is that no DMG file is mounting. So Apple updates, downloaded
programs (eg. Firefox) and so on do not mount after downloading. I have
tried downloading various apps with no success - it always says that the
disk image failed to mount. Surprisingly, however, one thing that DID work
was the MS Office 2004 update. Strange.
I have tried the Restore Disk Permissions option in Disk Utility, as well
as some online solutions to restore a potentially corrupted Disk Image
Mounter.
In terms of what is being affected, if I download something on my system
and it mounts, and I copy it across to Kaths, it doesn't mount. If I
download something on her system and it doesn't mount, I can copy it
across to my system and it mounts.
Her iBook appears to be behaving normally in all other aspects.
Ideas?

Here's a MacWorld forums thread about dmg mounting problems. See the last post for half a dozen ways to try to deal with it.
http://www.macworld.com/forums/ubbthreads/showflat.php?Board=UBB1&Number=369599
When you try what he calls "Procedure A" be sure to restart where it says. Also, you might possibly have to restart more than once for the system to adequately rebuild/replace the cache files. I hope something there works for you.

Dmg won't mount

I have one encrypted disk image that failed to mount. It accepted the password, just didn't mount. Other similar DMGs work fine.
I recreated the image from data in the trash, then dragged the bad one to trash. Now I can't empty trash because that dmg is "in use". I can retrieve it from trash, but can't do anything with it.
What can I try to make this image mount? Pretend like it's important data.
I've tried logging out and back in, no go. Tried repairing permissions, I didn't expect that to do anything, and it didn't.
I'm a new user (3 weeks). OS X has been horribly unstable. I'm trying to learn as much as I can before thinking about a reinstall.

Have you been able to use the printer with that particular Mac? Unplug the printer and then try removing the printer from your printer list, then reinstalling it.

DMG won't mount on Snow Leopard

This isn't a bug with Photoshop, so I didn't log a bug. The "photoshopcs6_p1_mac_032112.dmg shows an error of -4960 when you try to mount it. The file size is 1,231,479,172.

Thanks Chris. It's not often that a second download of a file would give different results, but in this case the second attempt gave a file size of 1,032,137,621, and that did indeed work fine.

Years of data gone, backup DMG won't mount "No mountable file systems"

Could someone help me here, I have this problem.
The reason for this was that I ran into some complications with my boot camp windows install and wanted to start over. After returning the boot camp FAT partition space to Mac OS X it froze while attempting to create a new boot camp partition. "Boot Camp Assistant" suggested I backup my "Macintosh HD" and re-partition my HD because "some files could not be moved." Ok so, I backed-up my "Macintosh HD" volume to a DMG using Disk Utility selecting the volume and clicking new image icon, it is compressed, it is Leopard. I then booted with Leopard install DVD and began the restore process. Everything was working smoothly until the progress bar stopped animating, waited awhile and forced restart. When I restarted my internal HD had only an "Applications" folder which ended its contents with a half copied iDVD.app preceded by 73 other apps successfully restored. Now worst of all my Backup DMG produces the "No mountable file systems" error. Help, oh please help!

Ok, here is the output. It shows there is a problem with the resource fork XML, just like yours Shad Guy. If only their were some specs available I could try to fix it myself. An Apple engineer could most likely fix this in 20 min.
Also, thanks for your help man, having people tell me to give up is the worst.

DMG Won't Mount. File Mount Greyed Out In DU?

Had this problem before.
I can mount the .dmg by double-clicking it but I can't do it in Disk Utility as the Mount command is greyed out.
I believe that last time I was told to hold the Shift or Option key down whilst selecting File>Mount but I can't get it to work this time.

Yes the grey "Mount" changes to "Open".
Last year someone told me how to un-grey the "Mount" in the File menu but I can't remember exactly how or find the original thread.
In those days I was on Leopard so maybe it's changed.
It's not a problem . . . . just one of those irritating little things.

Aperture 3 Trial .dmg won't mount??

Hi,
Has anyone had trouble mounting the 3.0 trial disk image? I've downloaded it twice, and each time I can't get it to mount.
I can mount other disk images just fine.

Worked fine for me, but I did it on a MBP with 10.6.3 at the time.

DMG won't mount on my Desktop

I have an Intel Core Duo 2Ghz processor I-Mac amd I am running Mac OSX Version 10.4.8 software and I have tried to download numerous software updates and haven't been able to use them because after the software has downloaded, the computer tells me that the disk image is being prepared and then tells me that the mounting has failed. An icon appears on the desktop, but when I double click it to open...nothing happens (and nothing shows up in my dock). It it a software update issue or what? I'm stumped.

I am having a similar problem when I attempt to download software from third party websites such as Adobe or Skype. The computer also tells me that the disk image is being prepared, then has failed to mount, as the device is not configured.
I have attempted to use the disk utility this does not work.
This problem seems to have only occurred after having installed Apple Software Updates.
I find this issue to be highly frustrating, time consuming and costing me money, ie., having purchased software online to download, it is failing to mount.
I hope Apple is not indifferent to this problem and is able to rectify or offer solutions.

Sims 3 DMG won't mount

I am trying to download the Sims 3. I bought it off EA games for MAC and everytime I try to download it, it says that "Error 4960". Can anyone help? What should I do?

Welcome to Apple Discussions:
Is the download complete? Usually there is a checksum you can use to verify the DL before doing anything further.
When do you get the error? During the DL or when you try to open it?

Mail preferences in encrypted DMG accessed even not mounted

I keep the contents of ~/Library/Mail on an encrypted DMG which i mount here when i need.
Sometimes, when i close mail and unmount volume mail mustn't get new messages, but it does !
Even if I reboot after unmounting.
I cheched ~/Library/Mail after unmounting ad it's empty. But if i launch mail it downloads new messages and recreate files.
Why is it happening? Is it a cache problem? how can i solve it?

Is there any chance anyone can help, this issue is becoming rather annoying especially as this iMac is less than a month old!
Thanks in advance!

DMG backup image won't mount

name-lt.dmg won't mount and says "File too large" as the warning error. I used Disk Utility to make this compressed image for backup purposes and now I'm afraid I won't be able to open it. A friend told me to use HexEdit to edit headers on the image. Does anyone have any advice? It's a 125gb backup image. All other images I have made will mount and work fine.

The image was taken using my iMac (10.9) connected with a firewire to a macbookpro running 10.7.5

Mount encrypted DMG and share as a shared filesystem over afp

I am trying to share the hfs+ filesystem that resides on an encrypted .dmg file. When trying to share the filesystem the only one that can mount this system is the person that mounted it on the localsytem. Is there a limitation on mounting .dmg and sharing the filesystem or is there a trick that i don't know. The end result should be a work group with an encrypted share.
Thanks

Try creating a disk image on your Desktop. If you have the same problem with it, do as follows.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

How do I get an encrypted dmg on a network share to automatically mount at login?

I need to mount an encrypted dmg that is stored on an SMB share to automatically mount at login. I've got the SMB share to mount at login as a "Login Item," but I can't get the encrypted dmg to mount.
A related question:
I've got a shell script that mounts my encrypted image, copies data using rsync, and then unmounts the encrypted image. I tried automating this using a cronjob, but cronjobs are nut run as $USER. Since the cronjob isn't run as $USER, the cronjob does not have access to the $USER's keychain and cannot authenticate to the encrypted dmg. Any tips on getting either of these to work?

I don't use SMB so I'm not sure whether this will work, but try it. Open a TextEdit window and type something like this:
smb://user:password@server/path-to-file
Make the obvious substitutions in the text, then select it and drag it to the Desktop. You should get a bookmark file. Double-click it to test. If it works, you can rename the file and put it anywhere you like. Add it to your login items.
If the above doesn't work, try again with "cifs" in place of "smb".
The "user:password@" part may not be necessary if the password is in your keychain.
