Apr 20, 2010 Introduction. DMG2IMG is an Apple's compressed dmg to standard (hfsplus) image disk file convert tool. It is derived from dmg2iso v0.2c by vu1tur. It will allow you to convert a DMG file into an IMG file that can be mounted as described in ManageDiscImages. A.dmg file is kind of like an USB stick in a file and can be handled more or less the same way. To install from a.dmg file you usually do the following: double click the.dmg to make its content available (name will show up in the Finder sidebar), usually a window opens showing the content as well. Converting.dmg to.iso file in Ubuntu Linux. Ubuntu is a common variant of Linux, complete with a user-friendly interface and full flexibility in customizing it via the Terminal window. Windows and Linux share the ability to open ISO files, which are similar to DMG files. Though DMG files are commonly associated with Apple’s operating system.
Ubuntu is a common variant of Linux, complete with a user-friendly interface and full flexibility in customizing it via the Terminal window. Windows and Linux share the ability to open ISO files, which are similar to DMG files. Though DMG files are commonly associated with Apple’s operating system, Mac, they can be opened in Linux with a few simple steps.
Step 1: Install dmg2img
Open up your terminal console
sudo apt-get update
sudo apt-get install dmg2img
Step 2: convert the .dmg to .img
Once dmg2img is installed, you will want to change our working directory to the .dmg you want to use. in my case, the image.dmg is on my desktop. ( /home/dan/desktop )
cd /home/dan/desktop
Once you are succesfully in your working directory, you are now read to convert the .dmg file.
NOTE: the second part of the command is a .img at the end.
Step 3: Mount the .img file
Now we are ready to mount the .img file into a new directory
Install Dmg File
mkdir /media/image
sudo modprobe hfsplus
sudo mount -t hfsplus -o loop image.img /media/image
Step 4: Convert the .img to .iso

The image is now mounted. We need to convert it to a .iso file now. Open Brasero, a program native to Ubuntu. It can be found in the “Sound & Video” section under “Applications.” When the window opens, choose “Data Disk” and then “Enable Side Panel.” (if Brasero is not installed, open up the terminal and type the following command: sudo apt-get install brasero )
Press “Image File” and “Burn.” This takes the IMG file and converts it into an ISO file. Wait for this to finish.
Step 5: Mount the .iso file
Enter the following commands into Terminal, where “image” is the name of the ISO:
mkdir /media/imageiso
sudo modprobe hfsplus
sudo mount -t hfsplus -o loop image.iso /media/imageiso
This will successfully mount the .iso file and you can proceed with your installation.

UNetbootin for Mac OS X can be used to automate the process of extracting the Ubuntu ISO file to USB, and making the USB drive bootable. The resulting USB drive, however, can be booted on PCs only. If attempting to make a USB drive that can be booted from a Mac, follow the instructions below.
We would encourage Mac users to download Ubuntu Desktop Edition by burning a CD for the time being. But if you would prefer to use a USB, please follow the instructions below.
Note: this procedure requires an .img file that you will be required to create from the .iso file you download.
TIP: Drag and Drop a file from Finder to Terminal to 'paste' the full path without typing and risking type errors.
Download the desired file
Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
Convert the .iso file to .img using the convert option of hdiutil
Note: OS X tends to put the .dmg ending on the output file automatically.
Run to get the current list of devices
Insert your flash media
Run again and determine the device node assigned to your flash media (e.g. /dev/disk2)
Run
(replace N with the disk number from the last command; in the previous example, N would be 2)
If you see the error 'Unmount of diskN failed: at least one volume could not be unmounted', start Disk Utility.app and unmount the volume (don't eject).
Execute (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
Using /dev/rdisk instead of /dev/disk may be faster.
If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start Disk Utility.app and unmount the volume (don't eject).
Run and remove your flash media when the command completes
Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick
Please notice: While all of the info and above commands are executed properly on a MacBook Air 3,2 (that is the 2010 version 13' version of the Air) the end result will not produce a bootable USB device, at least not with the image for Ubuntu 10.10 64-bit. When booting of the USB device the following message or something similar will appear: 'Missing operating system' and the process is auto-magically halted.
To get the USB device (e.g. a USB stick) to show up at all in the boot menu you also may have to reboot/turn on/off the computer a couple of times and also resync the partition tables using rEFIt. After doing this the USB should then appear as a bootable device while holding in the alt or c key when you are rebooting the computer. Notice that both the computers built in bootloader and rEFIt will identify the USB device as a Windows device, but that's not a problem and expected.
A workaround to the-usb-device-is-not-booting-problem is to:
Install rEFIt.
Create a bootable start disk using Ubuntu and a USB stick.
Create a separate partition on the Airs HD.
dd the whole USB stick to that partition.
Resync with rEFIt. Turn power off and on.
Select Pingo/Windows logo: Install should start. (Here you might want to press F6 to change parameters, e.g. use nomodeset)
Alternatively, burning a CD and installing via an external CD-drive will work fine on the Macbook Air 3,2.

Run diskutil list to get the current list of devices
