Dmg file help

i have a .dmg file that i am trying to mount and when i double click on it, it appears to be doing something, then i get this message:
'the following disk images failed to mount' and the reason is 'no mountable file systems'
is there a way to make it work?
thanks
Brett

It's a bad file. Try downloading it again. If you are downloading it from a P2P net like Gnutella be prepared to find a lot of files like that one.

When i try to open dmg file for newest version of itunes, my mac pro does not open to install and freezes my main desktop toolbar so i can't select the apple to shut down, it also enables me to open any other programs?HELP PLEASE

i've been forced by my comp to shut down several times by holding the power button because of the inability to select the apple and shut down correctly..idk if i got a rare mac virus or bug.. and some programs simply won't open when clicked on.. i don't know how this is possible after years of great performance..

Where did you get this "dmg file"? To install the newest version of any Apple software, including iTunes, all you have to do is use Software Update from the Apple menu. This doesn't download any dmg, it automatically installs the software for you.
Maybe try repairing your permissions from Disk Utility (in your Utilities folder).
Also - What version of OS X do you have? Please update your forum profile so we can help you better.

Need help recovering .dmg files from an accidentally reformatted external hard drive

Help?
I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled). The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the table information got overwritten, as the re-format took about 30 seconds. None of the recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).
Any suggestions on how I can retrieve these disk image files?

I am having .dmg files issues can someone help?

I have mds loaded on my macbook air. I had no problems downloading dmg files until I upgraded to Lion. Here is the error:
"MDS DWNLDA WOODGRAIN STAMP BRUSH Installer" is damaged and can't be opened. You should eject the disk image.
in smaller letts and grayed out it says:
"MDS DWNLDA WOODGRAIN STAMP BRUSH Installer" is on the disk image "MDS DWNLDA WOODGRAIN STAMP BRUSH.dmg". Safari downloaded this disk image today at 10:17pm from ec2-50-112-2-55.us-west-2.compute.amazonaws.com
cannel or eject disk image.
I have been using mds and downloading art work since I have had my macbook air for 2 years, it is not an amazon file so I am not sure why amazon is showing up. Please help as I don't know what to do and I know for a fact that the file is not damaged. I have downloaded and loaded this file in the past. I get this error no matter what I am trying to load that is a .dmg
Thanks!

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 models. 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.

Help! Can't open .dmg files suddenly, and can't find stuffit expander application!

My iMac is currently running on Mac os x 10.5.8, **out of nowhere my computer can't open dmg files. I can't seem to find the stuffit expander application anywhere in my hard drive either, which usually opens these files. Is there another application that can open dmg files? Help Please! I need to open multiple dmg files tonight and can't figure out a way around this. Downloading/running a new stuffit expander application also happens to be a .dmg file. If anyone can help me I'd appreciate it so much!

Do you mean DiskImageMounter was chosen or not?
No change on that .dmg or on on others?
If you want to apply DiskImageMounter to all you have to choose "Change All".
EDIT: Also, Repair Permissions from /Applications/Utilities/ Disk Utility.
Also, George Orville has some interesting advice in this thread
Note this advice is for 10.3 but much of it will apply here.

I download dmg files but cannot be open (not recognised). If I try try to use disk utility, it says the disk image unable to attach. Could someone pls help? Thnx

Hi, I am trying to install some programs (on mac book pro mac osx 10.6.8) that are downloaded in "dmg" file format. These are antivirus and security related programs. Unfortunately when I try to open the downloaded file, this does not open and I get message it is not recognised. I have also tried using Disk Utility but I get an error "unable to attach"l. This just started recently. I have downloaded the file several times but same problem recurs. Thanks for your help
PS: Other files directly downloaded from apple work fine.

curious to know your reservations about Kapersky!
They screwed up the first Flashback removal tool very badly, locking several users out of their accounts permanently. It took a day or so for them to react and post a revised tool, but the damage had been done.
They are one of several formerly PC only vendors who rushed to the Mac front back in the spring after the Flashback scare. I would advise giving all of those folks time to prove they really understand OS X before installing it on any of my Macs. There are several others who have proven themselves.
Since you are running what I assume to be a fully up-to-date OS X 10.6.8 you are not vulnerable to any currently known malware capable of impacting OS X or other Mac software. That's no guarantee there won't be something new show up tomorrow, but the chances of any commercial anti-malware software catching it before Apple can react is pretty slim, IMHO.
Now if you are concerned about Windows malware, that's a different story.

Can anybody help me to open a .dmg file on my MAC OS 9.2.2.

Can anybody help me to open a .dmg file on my MAC OS 9.2.2. the file is a Mac OSX 10.4 Tiger Boot Disk which i would like to run along side OS 9.2.2

Rincewind is correct is saying that DiskCopy 6.3.3 can mount many .dmg images on the desktop (thanks for the correction, R.). He is also correct in saying their contents will generally run only in OS X.
Interestingly, I find by testing that Disk Copy 6.4 and 6.5b11 are unable to mount several .dmgs that 6.3.3 mounts OK.
Trying to install OS X from a disk image that has been burned to disk in OS 9 is going to be a fool's errand, I'm afraid. Buy the correct installer disc set.

5-powerbook g4 with dvd drive and firewire (for some reason will not read the tiger discs i just burned, even though ive already used them on the ibook g4
6-mac pro with firewire and dvd drive, but the dvd drive is broken.
so seems to me, every computer i have has a weakness for exactly what i need. what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire. if you have any suggestions on what i should try with the supplies mentioned above, please inform me. thanks!

what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire.
You can't unless the PowerBook is running Mac OS X Server, in which case the NetInstall feature can be used.

I am having trouble with replacing my old Firefox version 3.6.3 with the new 9.0 version on my Macbook. I have it downloaded as a dmg file, but I keep getting a message that the opertion cannot be completed because the item Firefox is in use...HELP!

After having the issue with my photos being blocked on Facebook, I was told I needed to upgrade to the newest version of Firefox and that the version I am currently using (3.6.3) is no longer supported with security updates. I have tried to follow the steps in the upgrade process through Firefox itself, but have been unable to do it...I would love step by step instructions to walk me through it as I don't know what I am doing wrong.'''bold text'''

If there are problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the disk image (dmg) file to the desktop
*Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
*Trash the current Firefox application to do a clean (re-)install
*Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data if you uninstall and (re)install Firefox.

The dmg files have downloaded to the wrong folder - not finished with the install process

The dmg files have downloaded to the wrong folder - I am at the part of the download/install process where the "Welcome" screen appears asking for me to agree to the license agreement. Somewhere on your site, I read that they should NOT go to the applications folder but to the "Users" folder. Can/should I move/drag the folder with the dmg files into the "Users" folder"? If so, before or after I complete the install? I am running MAC OSX 10.7.4 on a MAC Mini.
Also, when the trial period is over, I will use the license number for the purchased software disks, should the dmg's/folders then be moved to the application folder or stay in the "users" section? I have Purvhased Adobe Photoshop Elements 10 and Adobe Premiere Elements 10, but somewhere on your site it was suggested to download them instead and use the license code at the appropiate time. If someone can help with these questions, I would appreciate it. Thank you

Hi,
In the Welcome screen, you can accept the license agreement and can go ahead with the installation. You will be asked for the serial number. If you don't have one, install it as a trial application. By default, it's installed in the Applications folder. However, you can change the installation folder in the third screen, if you have a reason. Please see the screenshot below:
After installing, you can't move application to a different directory by dragging. You need to uninstall and install it again in the folder of your choice.
Thanks,
Sunil

How do you use a dmg file image to download windows through boot camp?

after reaching my limits in finding the answer to this problem/question i have, i finally decided to post it for everyone to feel my pain
so i dont know if i would be spanked or something but i downloaded a windows xp sp3 from the internet through torrent
it was originally an iso file so i changed it to a dmg by using disk utility
now heres the problem:
after that, i opened the dmg file image and mounted the virtual drive
then when i started up the boot camp installation and clicked the "Start Installation" after about fifteen seconds it said that it couldn't find any disk installers!
AARRGG
it would be awesome if someone could help me
and this other question that i did not mention above is:
when you run windows xp on Parallels, is it slower than when you use windows on a PC or through boot camp?
thanks and hope you have a nice day

Hi and welcome to Discussions,
so i dont know if i would be spanked or something but i downloaded a windows xp sp3 from the internet through torrent
I don't spank you for that but I also don't comment on it as maybe this post will be deleted soon !
it was originally an iso file so i changed it to a dmg by using disk utility
now heres the problem:
after that, i opened the dmg file image and mounted the virtual drive
then when i started up the boot camp installation and clicked the "Start Installation" after about fifteen seconds it said that it couldn't find any disk installers!
The BootCamp Assistant requires Windows to be on a bootable CD/DVD and will not work with any kind of images, iso or dmg.
when you run windows xp on Parallels, is it slower than when you use windows on a PC or through boot camp?
Yes, since it is not running 'natively' , using the real hardware, but it is running on a virtualized environment.
How much slower really depends on the kind of programs you use in Windows, with typical Business/Office programs you might not even notice any slower performance, but with programs that depend on having access to the 'real' hardware, you will notice the slowness often right down to be un-useable.
thanks and hope you have a nice day
You too
Stefan
