How to create a OS X Mountain Lion Bootable USB drive on Ubuntu?
Solution 1
As you want to create a LiveUSB you need a .iso
image to make it. The Mac image is a .dmg
file, so you must to convert this file into .iso
, and then install it.
Install DMG2IMG
DMG2IMG (1, 2) will convert the .dmg
image into a .iso
image. To install open a terminal and enter this command: sudo apt-get install dmg2img
Convert the Image
With dmg2img
you will create an .img
file and this file will have the same format as an .iso
file, you just need to replace the extension.
In the terminal enter the following commands or paste the script with the necessary modifications:
# Replace "OriginalFile.dmg" with the filename including the extension
# of your file. The extension will be replaced where necessary unless
# you want to specify the filenames yourself.
filename="OriginalFile.dmg"
# Replace with your file name and it will create the IMG file
dmg2img -i "${filename}" -o "${filename%.dmg}.img"
# Note that the extension of the first file is ".img"!
mv "${filename%.dmg}.img" "${filename%.dmg}.iso"
Make the LiveUSB with an ISO image
Now you already have the .iso
image, with which you will make the LiveUSB. Several tools and answers exist to help you create bootable USB drives, some are specific to PC/MBR booting (Bootcamp) where Macs and newer PCs since Windows 8 require/support UEFI booting.

Solution 2
why not just dd
the .img
file after conversion?
sudo dd if=/path/to/orig.img of=/dev/s**

I already know how to do it on Mac OS X (plenty of instructions online).
But is it possible to do it on Ubuntu? If yes, how?

Lucio over 11 yearsI think that your solution (Question and answer) already exist in this post.

Jake Badlands over 11 years@Lucio Unfortunately, no. This post tells about .iso image files, but I have .dmg image file, which is different.

karel about 9 yearsSince you asked,
dd
is a good program if a bit hard to understand for some, howeverdd
has one major drawback compared to GUI USB creator applications . Sometimes when youdd
an .img file onto a USB drive you can't reformat it if you want to reuse the USB drive. The GUI live USB programs don't have this problem. -
Jake Badlands over 8 years@karel actually you could use a software like SDFormatter with
FORMAT SIZE ADJUSTMENT = ON
to restore the true capacity of USB drive (after dd'ing USB drive could appear as e.g. 50 MB instead of 4GB and standard built-in OS software sometimes can't restore it) -
karel over 8 years@JakeBadlands I downloaded SDFormatter to try it, but ClamAV reported a malware threat on the file that I downloaded, so I'm sticking to my tried and true method which uses programs from the Ubuntu Software Center: askubuntu.com/questions/496309/how-to-unboot-my-bootable-usb/…

Jan Segre over 6 yearsIt should be possible to use
parted
to recreate the partition table on add
'd USB stick. It makes sense to me that some GUI tools don't support recreating the partition table and thus are stuck with whatever size was put there whendd
ing, but it would seem strange if it couldn't be done with parted, is this known not to work on any USB stick?
