Making a bootable OSX USB from dmg on Linux
Install dmg2img sudo apt-get install dmg2img Convert DMG image file to ISO file dmg2img -v -i /path/to/image_file.dmg -o /path/to/image_file.iso Copy ISO image to USB sudo dd if=/path/to/image_file.iso of=/dev/sdb && sync sdb is an example. In your case it might be different Edit You can do the conversion and actual writing in one pass, if you don't need the .iso afterwards: it will take half the time as converting to .iso and THEN writing to the USB device. Just do: sudo dmg2img -v -i /path/to/image_file.dmg -o /dev/sdb Again, sdb is an example. In your case it might be different.
