Convert a .dmg to a .iso


Mac formatted disk image (.dmg) cannot be directly burned on Windows or Linux systems.


One can convert a .dmg to a CD master via the Disk Utility application embedded in OS X, or by opening a terminal window and issuing the following command:

hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso

The output file will be named savefile.iso.cdr – you may strip the .cdr and burn the .iso with any standard utility for doing so.
