Dmg file ****

hi guys for a while the problem was that i couldnt install a couple of dmg files due to the error message "file unable to mount" and " file unrecognized" so after trying everything on these boards i did a fresh install of tiger on my g5, now no dmg file will mount. if theres an apple mac god out there please help me as my studio is down and i need it up and running

I think those kinds of errors mean there was no filesystem on the diskimage. Usually they come from bogus Gnutella filesharing servers, as part of a strategy to sabotage software and music piracy.
Sorry about the reinstall part...

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.

The difference between a .dmg file & a .cdr file (using Disk Utility) ?

Hi,
In particular, I created both from a DVD using Disk Utility.
When I chose "read only" a .dmg was created.
When I chose "DVD/CD Master" a .cdr was created.
They are exactly the same size.
Is there any difference ?
Thanks in advance.
Pat De Marco

HI Pat,
From Wikipedia: A file with the extension .dmg (an abbreviation for disk image) uses a disk image format commonly found on Mac OS X. The format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are "mounted" as a drive within the Finder.
From: Wikipedia .cdr and ISO
ISO image
Filename extension .iso
Uniform Type Identifier public.iso-image
Type of format Disk image
Standard(s) ISO 9660
An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization) format that is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR. The name "ISO" is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible to ISO 9660.

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

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.

Files disappearing from mounted .DMG files

Hi, I've had this issue occur a few times in Tiger and I'd like to know if anyone else has experienced this and if there's a known workaround. Sometimes, when browsing a disk image, or, less commonly, a physical disc like a CD, files in the Finder will seem to disappear from the image/disk when clicked on. First the filenames will go, then the files themselves, and evidently those files then become unreadable in general as applications can't access them. I don't get any error messages; it's just like the filesystem on that disk eats itself away and vanishes. I can unmount the disk without any issue.
I'm having this problem right now with any disk image I mount on my XServe -- it goes through the "Verify" step just fine, shows up on my desktop, I can browse and even open files, but inevitably within a very short period of time the above occurs, and it becomes useless. I KNOW it can't be the .dmg file that's the problem, because if I share the .dmg over Personal File Sharing and mount it from another Mac, this problem does NOT occur. It's just on the one Mac hosting the files. Any idea what this could mean, and what could solve it?
Also, I know a lot of times a restart will cure this weird little glitches, but I would really like a solution, if you know what I mean... particularly on a server, I cannot afford to restart whenever I have a problem.

Sounds like you have run into a very strange, and unfortunately no uncommon, bug involving file systems from either servers or FAT 32 mounted external drives. See this discussion:

Read on down away to see some replies from people who did some pretty thorough investigations of the problem.

Many Thanks, Kurt.
I knew I'd seen the solution you've provided somewhere - either in MacWorld or MacFormat - but couldn't remember the Gatekeeper bit!
I shall save it somewhere VERY safe now in case this happens again …
You have made an old man very happy and saved me from worrying that senile decay had suddenly set in. (I was 70 last week so you might understand the situation from that.)

I am trying to upgrade iPhoto from a .dmg file ???

I am trying to upgrade iPhoto 9.4.2 to 9.4.3 on a Mac Mini with Mountain Lion. When I run the iPhoto9.4.3Update.dmg file, I get the alert:
The version of iPhoto installed on this Mac must be updated through the Mac App Store. Check the Mac App Store to see if an update is available.
When I close the alert, it shuts down the update.
Since at our location our only option to get on the internet is via a 3G modem with a data cap of 5 GB per month, we take a laptop into the local library, hop on their wifi, and download dmg files for large upgrades like iPhoto (in this case, 766 MB). This has always worked before - what is different here?
Since we were near the end of our data month and still had a GB left, I then tried the software update route from the Apple menu on the Mac mini. It started downloading the 9.4.3 update which was only 177 MB. 2 hours later it had just finished the download and suddenly continued onto another download (still in the iPhoto upgrade) of a 1.2 GB file. So I aborted. So my 2nd question is what was happening here.
And my 3rd question is what to do next?

Evidently there was more than one update listed for your Mini. Next time launch the App Store app in your Applications folder and log in with the Apple ID used to purchase your Mini. Click on the Updates folder and look for available updates. There you can select one at a time for installation.
Look in the Download folder in your Home folder to see if the 9.4.3 update is there.

I downloaded an update for my Safari web browser to "snow leopard". When I click on the .dmg file, a window opens up with a .pkg file but when I click on the .pkg file I get a prompt saying that it doesn't know what program to open it with.

I suspect if you're trying to open a file in 08 that's been opened in 09 the file has been updated to 09 and will not open in 08.

Upgraded to OSX 10.8.2 and now I can't run any downloaded dmg files. Says "the Following disk images couldn't be opened". and then say's there "isn't enough disk space" I'm pretty sure it has something to do with apps that are not approved by the app store. How can I turn it off?

Select your hard drive in the Finder and choose File -> Get Info. What is the available space?

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.

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

Grey Screen, won't boot from usb. Only have a PC to create a boot USB. How can I reinstall OSX with a .dmg file?

I recently recieved a macbook that I was told was broken. She didn't know what was wrong with it, but she told me I could keep it if I wanted to get it working again. Its http://support.apple.com/kb/sp579 this model. I got the laptop to power on, but the apple logo and the spinning wheel under it kept spinning forever. So with me and my "Amazing" knowledge of Macs, I thought it would be best to reformat the drive on my PC via sata cable to FAT32 (which I was told is a format that mac devices can read/write on) and install OSX from usb. So I have a .dmg file and used TransMac to format the usb and make the usb drive bootable with the .dmg.
I formatted the drive to FAT32 and plugged it into my macbook and I get a folder and a question mark blinking on the screen. After looking at some forums online, I found that the error occurs when you don't have the correct filesystem to boot or something along those lines. So I try rebooting the computer while holding C, to boot from an external device (such as USB). Nothing. Again the folder and question mark blink on the screen. I look at some other boot option keys and try all of them. Shift for recovery mode, D for apple hardware test, Control, option, P, and R for resetting NVRAM and PRAM. Everything! The only things that differ slightly are when I press Option for startup manager, N for NetBoot and Option+N for internet default boot image. When I press N and Option+N, I get a blinking globe for about 5-10 seconds and then the folder and ? blink again. When I hold Option for the startup manager, I get a white screen and my curser, which I can move around the screen, but there is nothing to click on, its just white.
Currently I have a USB flash drive plugged into the macbook with a .dmg OSX installer on it via TransMac and for some reason, my macbook doesn't want to try to load it. Either I have the wrong file format for the installer, or my macbook is having problems. I read that the hard drive may be the problem, except I can use it on my PC so I know that it works fine.
If anyone has any information about how to fix this, or any ideas. Please let me know! I would very much like to get this macbook going again.

The correct format for Mac OS X is not FAT-32.
As the computer shipped with an install-restore disc DVD set that could be used to start the computer as an emergency disc and use the Utilities on the Installer, without running the Installer itself, to format, attempt repair, and perform a few different system installs or reinstalls, this is where the correct format would come from.
Was there documentation to confirm the build year and model information, such as to refer you to the product page link you posted above?
If accurate, that MacBook shipped with this custom grey
install-restore DVD version of Snow Leopard:
Original OS
Mac OS X 10.6.1 (10A2047)
Maximum OS
Latest release of OS X
AirDrop
Supported
Hardware Test
AHT 3A181
And to be able to restore the basic OS X to that level, official replacement discs for that computer should be ordered from AppleCare; to facilitiate obtaining correct ones, you should find the product serial number. There likely would be a fee involved. The replacement disc set may have a different number than the one in the information box above, but would match the hardware series by Apple standards. And a replacement disc may not have the original extra applications that shipped with the computer when new. Those original discs are part of the retail computer, an essential part number, like the power adapter, and should be included with the computer even after an OS X upgrade, since they allow basic access without using the internet.
The remainder of the Snow Leopard 10.6(.8) would be a download Software Update Combo v 10.6.8, either direct from Apple servers or through the computer's running Software Update. Once the computer is up to date in Snow Leopard, 10.6.8, then one could visit the Mac App Store, App Store, and iTunes Store; from the Mac App Store, and you could check/get the latest upgrade to Mac OS X, 10.9.2. An Apple ID is required to access.
The computer may not support Mavericks 10.9.2, or may be able to, but could use an upgrade of RAM capacity.
If your model and build year series info is correct:
Maximum Memory
8.0 GB (Actual) 4.0 GB (Apple)
Memory Slots
2 - 204-pin PC3-8500 (1066MHz) DDR3 SO-DIMM
For more information see the database download http://mactracker.ca
and also compare specs with macbook models at everymac.com.
The newer OS X systems that can use a Recovery HD partition on the hard disk drive, can start from there to repair their hard disk drive, and reformat the section where the Mac OS X runs, and reinstall that. Since there is no likelihood of that still being on the drive once it was FAT-32 reformatted, it will not be present to assist in attempts to reformat the drive; if the computer had been upgraded past Snow Leopard 10.6, to a later system that would have used the recovery partition, or the later internet recovery system. That goes to Apple Servers to use OS X Utilities and reinstall the system, helpful for computers without optical drives or system media. Your MacBook with 10.6.8 installed, then had to access the Mac App Store, to get 10.7.5, 10.8.5, or 10.9.x
Identify your Mac lookup by model number or serial number:
https://www.powerbookmedic.com/identify-mac-serial.php
Anyway, the hardware in the computer may need some inspection, troubleshooting, and maybe repair; but the original DVD install-restore disc has an Apple Hardware Test on it, for that series build model macbook. That could help in troubleshooting some aspects of the computer. Could be the hard disk drive failed; or if someone tried to upgrade the RAM, the system may not have worked correctly. Hard to say how it was messed up, at this stage. There are several possible causes.
Hopefully you can get the correct disc set from AppleCare.
You can call Support number, or use Contact Support page.
Good luck & happy computing!

I can no longer make dmg files in disk utility since upgrading to Mountain Lion

Hi everyone,
I'm a videographer, and have been using the facility in disk utility to make dmg backups of my media cards. It's proved to be a neat and tidy way of doing things, and is my equivalent to storing videotapes.
However, I no longer can make them.
My technique has been to:
1. select the memory card in disk utility
2. press new image
3. browse to destination for the dmg/hit save
4. sit back and wait for the process to complete.
this has been working for me in Snow Leopard, but not in mountain lion. I can't identify any other variables that have changed except the OS upgrade.
Firstly 'Authopen' prompts me for username/password. After username/password it starts creating the image, but stops with an error;
"Unable to create "SD-Card.dmg." (Device not configured).
The card is sitting in a media card reader. I tried another card reader that resulted in;
Unable to create "SD-Card.dmg." (Input/output error)
Anyone experienced this, or any ideas on what to try? As the card readers both work insofar as they show the memory cards in the finder etc, could there be a disk-utility-specific problem with them? Or do I need to change my procedure? I can copy the files to the hard drive and make a dmg from a folder, but I'd rather not have to do that.
thanks.

Maybe just corrupted Disk Utility preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.DiskUtility.plist
Click Go then move the com.apple.DiskUtility.plist file to the Trash.
Restart your Mac then try creating a .dmg file.

Is there a way to create a .dmg file for a DVD inserted into the system

I am wondering if Snow Leopard has integrated any tools that can create a .dmg file for the CD or DVD inserted into the system?
If not, any recommendations for freeware 3rd party tools? Thanks

Insert the disc you want to create the .dmg from, then choose the disc in the left hand pane of Disk Utility. From the File menu, choose New > Disk Image from (name of disc).
EDIT: This is basically how it's done; however, there may be other steps involved, depending on the type of disc you're trying to copy and what your goals are with the .dmg. If you provide more details about what you're trying to achieve, maybe we can help you further.
