Corrupt Apps/Disk Images Wrong file creator wont launch

I have a strange problem. Ive just upgraded to os 10.8 with a clean instal. I was in the process of reinstalling my applications. I keep them on a disk image on a external drive. The drive came unplugged by accident. when I re opened the disk image I got a message that the image could possibly damage my computer do I want to mount it. I did and copied all my installers off it.
Now when I open any of them for example skype, I click on the dmg, the disk image mounts and I can copy the app from it. When I click on the app to launch it I get the gatekeeper message, it says it was created by Preview. [see screencap] and when I click open nothing happes.
I can download a new copy of skype and it works. I have limited bandwith with my isp so Id like to avoid redownloading all my installers if possible. Any ideas ?

Thanks. It starts to launch, gets to the point where you can see the doasboard then errors out.

Disk Image (.dmg) files no longer mount

Since updating to 10.4.9, I cannot mount disk image files. When I double click on them, I get an error dialog from Finder which reads, 'The Following disk images failed to mount.' Reason: 'Device not configured.' I suspect that some essential software, 'Disk Copy' and/or 'Diskimagemounter' did not, for one reason or another install with the rest of the update. My computer did crash when the update was almost complete, but after a restart, everything seemed to work OK, except for not being able to mount disk images, which in this age of downloadable software basically makes your Mac dead in the water. Any solutions, suggestions would be greatly appreciated. Thanks all!

Your Mac crashed before the update installation process was complete and before the prompt to restart?
If so - Houston, we have a problem. ;~)
Did you check your boot volume for any directory problems with Disk First Aid repair via Disk Utility when booted from your Tiger install disc immediately before the install and did you quit all running applications before the install?
Regardless and as a first step, check this link for system troubleshooting procedures and when doing so, follow all steps/instructions in the order provided.
http://www.thexlab.com/faqs/repairprocess.html
Test if this resolves the mount disk images problem since you should download the 10.4.9 Combo Update and re-install 10.4.9 since your Mac crashed before the install was 100% complete.

Disk Image/Original File (iDVD 5)

I just finished saving a iDVD Project as a Disk Image. I know you can move the disk image file to another computer for burning. Also you can create multiple copies of a DVD from a disk image.
This leads up to my question(s)...
When you have created a disk image, What should you do with the original file if you have really no use for it?
Do I need to keep the original file for some reason?
Should I trashed the original file to save hard disk space?
Thanks in Advance!

Susan, just as a point of protocol, new questions ought to be posted as new topics. Anyway, that said...
Ths disc image is a file, like any other file. It's just big. So to get it to the other Mac, either use the network (I'm assuming the machines are networked!): Click the network icon in the finder sidebar, click the host name of the other Mac in the finder window, and go through the steps of connecting as a remote user. (Depending on how the network is structured you may have to poke through some folders to find the other machine.) Once you have the remote share mounted, it's just a drag and drop Finder copy.
Your alternative is to plug in an external firewire or USB disk, copy it there, carry it over to the other machine, and copy again.
On the other machine, you burn the disc image with either Disk Utility or Toast. Start up Disk Utility, and select File->Open Disc Image. Then select the disc image in Disk Utility's sidebar and click the burn button. A similar procedure applies with Toast - select the disc copy mode and then select the disc image option.

USB Flash Drive (with password protected Disk Image) copies files very slowly. Why?

I'm backing up some data onto a 32GB flash drive that I've put a password-protected Disk Image onto, and am copying this data into, but it is achingly slow. It's taking hours to copy just 500MB!
I have another 64MB flash drive that I have set up the same way, but this one copies files very quickly. I can't spot any difference between them in Disk Utility/System profiler.
For the record, the process I've used for bothe drives is reformatted to Mac OS Extended (Journaled), then created a new Disk Image onto each drive (just a bitsmaller than the maximum size of the drive to enable it to fit) with 128--bit encryption.
Does anyone have any idea why the 32GB drive would perform any differently? I am using the same USB port on my iMac for each drive, but am getting very different copying speeds. It's driving me nuts! Many thanks.

The drive seems to be working fine if I copy files onto it outside of the Disk Image file (there's about 200MB of free space left over after I added the DMG). So I can only deduce from that that it is something specifically to do with the DMG itself. Though, as mentioned, I compared the DMG on my (fast) 64GB stick and the DMG on this problematic (slow) 32GB stick in Disk Utility/System Profiler (and I originally set them up in an identical way, as far as I am aware), and they seem to be the same. But one is performing achingly slow. Even dropping a file into the mounted DMG takes a few minutes to even think about it. It's very odd.

Merge Disk Image Shadow Files

I've fallen into the habit of mounting disk images with a shadow file to save disk space on my laptop. I'd like to merge the shadow file back into the disk image in order to better preserve the changes I've made. After reading the man page for hdiutil it appeared as if this task would be as simple as performing a "convert," specifying the image file and the "ov" flag in the options. However, I continue to receive "Resource Busy" errors despite the image being unmounted. Am I attempting the impossible, or have I simply missed the solution to my problem? Would anyone with any knowledge about hdiutil be able to share some insight?

I think you can not use the option '-ov' with the verb 'convert'; convert into a new disk image will work
hdiutil convert old.dmg -format xxx -o new.dmg -shadow shadowfile
After checking that new.dmg is OK, you may remove old.dmg. Or do you mean you don't have enough disk space to do this?

Recover lost disk image backup file

I think I may have screwed myself, but basically I am trying to get back the sparseimage that was lost when I tried backing up my internal hdd to an external using SuperDuper. My issue is that the external HDD was formatted as NTFS so I was using the NTFS-3G driver for write access. So something must have happened when I tried to remount and and the file was lost. This was after running a checkdisk on a windows machine to get the ntfs partition to show up again. So basically I am trying to figure out what kind of software I could use, if any, to get this 80gb disk image back. Also I should note that I used compression when backing up the disk image so I am thinking that this might make my problem even more complicated. Any help or advice would be appreciated.
Thanks.

Cool, Ya that program did a pretty good job. It seemed to have found my lost directory structure. However like I mentioned I think I'm running into an issue with the compression that was ran on the image after backing it up. A feature that I am now regretting using. Because when I try to recover a file, like a jpg, preview says it can't preview the file. And opening plain text files gives me what appears to be binary or hex etc. So I am thinking I am running into issues where the files are still compressed and I need to figure out how to decompress them first before I can fully recover them. I was considering trying to just recover the whole directory structure and renaming the the top folder to a .img or .dmg file but I am not sure if that will work. Any ideas?
Thanks again.

Wrong file opens on launch-very strange

Hey I am having a very bizzare problem and I am hoping someone here can help.
The animation in question runs perfectly fine on my computer, but when I emailed it to my colleague, she encountered the following odd behavior:
Clicking the shortcut launches another, seemingly randomly determined, swf file elsewhere on her computer (in a different directory). Deleting this file causes the shortcut in question to redirect to a different, also seemingly random file. If she deletes all of the swf files on her computer besides the one in question, the file refuses to launch, giving a system error saying it doesn't have the right program to open the file, as if she didn't have flashplayer. Then, restoring a deleted swf file from the trash bin resulted in that file being redirected to (and opening), regradless of the directory we placed it in.
I am absolutely confused.
Any ideas what could be going on here?

We just ran into the exact same problem here on a coworker's computer, and were able to resolve it.
When we Control-clicked the .swf in question and looked at the "Open with…" menu, the only application listed was the weird bogus .swf that had kept on popping up. It had been packaged as an application, and she didn't actually have the standalone Flash Player app installed — just the browser plug-in, so her computer kept trying to use this executable .swf to open the file she wanted.
Once we installed the standalone Flash Player app, .swfs opened just fine.
Hope this is helpful to someone out there!

Sparse disk image bundle file WAAAYYYY too big

Hi everyone! I'm currently using a Time Capsule in conjunction with Time Machine AND as an additional external hard drive. I decided against using the drive with Time Machine and deleted all my old backups (using the finder window in the Time Machine program). However, no space was cleared on my disk; i.e., the .sparebundle file is still HUGE! I have a 500TB version of the TC, with about 100GB being used on the hard drive and 204GB being occupied by the sparsebundle file. Is there a way to reduce the size of the sparsebundle file? I had thought deleting the backups would clear the desired space.

First you need at least two current backups of all the files you want to keep in your home folder. One backup is not enough to be safe. Warning: Time Machine does not back up a legacy FileVault while you're logged in.
Then you need to delete most of the data in your home folder. No less than about two-thirds. Deleting means moving to the Trash and emptying the Trash. Log out and log back in. You should then be able to deactivate legacy FileVault in the Security & Privacy preference pane.
Finally, you need to restore the files you deleted. That will be easier if you don't use Time Machine to back up. If you do use it, you'll have to dig down into the backups folder to find the most recent snapshot of your home sparsebundle, then mount it and copy the files back to their original location. You can't use the time-travel interface for this purpose.
If you restore everything, you may fill up your boot volume again. Some of the files may have to be restored to a secondary storage device, which you will then have to back up along with your primary device.

Disk-image files- file size

I have created a disk-image file on my backup hard drive to save important data. This has 2 folders of around 180mB. I am now trying to save more files and the message comes up that there is not enough free space to copy the file. Do these disk-images have a certain size and how can I determine this. Is there an option to create bigger image file sizes. I would ideally like to create disk-image files up to 4 gB and then burn to DVD for backup.

Welcome to the Forums!
Yes, disk images have the size specified when they are created. You can't increase it, you need to create a new, larger disk image and copy the files to that.
You can see the size by selecting the disk image then File menu > Get Info, or by mounting the disk image, opening it and looking at the bottom of the window.
Use Applications > Utilities > Disk Utility to create a new disk image. There's a default choice for 4.7 GB (the capacity of a DVD).
Hope this helps...

Firefox 8.0.1-4.dmg - downloads - could not be opened. Quick Time Layer cannot open files in the "Disk Image" Format - What do I need to do?

I get the above message when I try to download Firefox updates.

That is a disk image file and you can't open that in an application.
<br />
Make sure that Firefox gets installed properly.<br />
Open the Firefox disk image (DMG) file with a double-click if necessary and drag the Firefox program to the application folder on your hard drive.<br />
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

"Back Up Disk Image cannot be mounted" AEBS and Time Machine

Hi all,
I am hoping someone can help me. I recently purchased an Airport Extreme and was able to connect a G Tech Hard Drive to it and use it as the Backup Disc in Time Machine (thanks to help from other users in the forum). Until yesterday, the backups started failing and stating that the backup disc image cannot be mounted. Prior to the backups failing i tried to manually delete some of the backups to create space on the Drive for other shared items. I was unsuccessful at deleting any of the backups, but somehow managed to corrupt the disk image. The error i am currently receiving is "time machine backup failed, Backup Disc Image cannot be mounted" I have checked in Airport Utility, the drive is still online and accessible through finder. It is visible through Time Machine, but somehow the image has been corrupted? Help me please, I am sure my lack of attention to detail in deleting files manually had something to do with this. Help!Help!Help....need to have regular backups.... Thanks so much

Fix to the problem-- Back up Disk Image could not be mounted

In order for TC to backup your entire HD it needs to create a Disk Image on your Mac. For example you would have seen your computer do this operation if you ever installed programs on your Mac computer.
I actually had this same problem and I searched the forum for answers. One fix that I found was that your computer might actually not be named. To fix this click on the apple in the upper left hand corner and then go to >System Preferences. Then click on >Sharing, after you do that you will see Computer name at the top. Type in whatever name you like for that part and then also turn on file sharing by clicking the box next to it below.
The other fix to this problem...which was actually the solution to mine, was that during setup 2 files for a Disk Image mount were created onto the Time Capsule itself. It is only supposed to have one. *In order to fix this problem-->If your Time Capsule is setup so it allows file sharing you should be able to see it as a connectable disk drive in your Finder window under sharing. Click on Time Capsule from there and enter in you password. You should now be able to search though the files on it. Since this is your first time setting it up there should only be one file visible on the Drive and that one file is what creates the mounted Disk Drive...(What I found on my Time Capsule drive was a file labeled with a bunch of numbers and then a Shared folder and then another file with a bunch of numbers in that). For me it actually turned out that the first file was not working properly but the one in the shared folder was. So I deleted the first file and dragged the second file that was working out of the shared folder and into the main part of the Time capsule Disk and then deleted the shared folder.
The way you can tell which file is the correct one is by double clicking it, if you get an error message right away, delete it. If it starts to load, then that is the file you should keep. After I did this mine worked fine and backed up my disk last night. I hope this helps

I have had the time capsule since it first shipped. In that time I've TWICE suffered a corrupt backup disk image (which I checked by trying to hand mount it by selecting the TC under sharing, and trying to open the sparse image - each time it failed and reported an unfixable error). Each time this occurred after the machine had been working flawlessly for 3 or 4 weeks. This makes the machine completely useless in respect of Time Machine. The disk seems to check out as I've just zero'd all data and it did not report a fault, and I have now reset the capsule (using the hole at the back) hoping that perhaps I can give it one last shot. It seems to me that basing these backups on a diskimage is a bad idea because in principle you could lose a single bit and the diskimage will not mount (unless there's redundancy in whatever header information etc. it uses) and then you lose ALL your files. I would have thought that backing up as individual files would be more robust to occasional corruption. Anyhow, this is all very disappointing, and I've been in touch with an Apple rep I deal with to seek advice. Apple need to fix this. I don't know if it's a problem with Time Capsule, or Time Machine.

Disk image will not initialize.

After downloading several times, disk image will not initialize. Dialog box -"The following disk images couldn't be opened Firefox 33.0.2 not recognized."
Mac OSX 7.5.2

Thanks for the reply - unfortunately I can not see the Firefox Disk image, the file that I downloaded shows up, but does not create the Disk Image required to begin the installation process.
I have re-downloaded the file from Mozilla several times with the same result.

Disk Images won't open after update to 10.4.10

After updating to 10.4.10 disk images (dmg-files) won't open any more. I get the error message "The following disk images failed to mount:.. Reason: Device not configured". This happens every time on every disk image. These same images mounted just fine before the update.
Any ideas?

what if the disk image is on an attached FireWire Drive?
there is no OS on that drive, so I can't repair permissions.
I have two disk images on it: one opens fine, the other I get "no mountable file systems"
It opened just fine a few weeks ago

Putting info into an Encripted Disk Image...?

I created an Encripted Disk Image to file some sensitive things in BUT how do I drag them into it...I show a .dmg icon but I cannot drag any folders into it...how do I go about this..?
Also when I click on the .dmg nothing happens...and it shows a folder of this under '/Volumes' which I can't find....HELP

robert larkin,
In case anything here might be of help to you.
1.
When I create a .dmg and save it to Documents, the drive icon appears in the top portion of my sidebar in the Finder. I can double click to open it, add items, delete items, and then eject it when I am done. I can put the .dmg file wherever I want it to be stored.
2.
Here are three links which I have used to figure out how to work with disk images.
