Converting image files on your Mac is easy thanks to a command line utility included in Mac OS X called hdiutil. Simply launch the Terminal and use the commands below, replacing the path and image file with your own.

Convert a DMG file to ISO

hdiutil convert /path/imagefile.dmg -format UDTO -o /path/convertedimage.iso

Convert an ISO file to DMG format

hdiutil convert /path/imagefile.iso -format UDRW -o /path/convertedimage.dmg

This tip is particularly useful if you have a CD/DVD burner on a Mac (or PC) and not a PC (or Mac) and you need to burn a disk image using the other machine.

    Worked great, but my code looked more like

    hdiutil convert “/path/imagefile.iso” -format UDRW -o “/path/convertedimage.dmg”

    other wise it gave me an error “only a single input file can be selected”
