Many software products come today as ISO CD images. Prior to installation they need to be written to CD. On Mac OS X this is very simple. Steps are:

  • Get and save the ISO CD image
  • Insert an empty CR-ROM into the SuperDrive
  • Start a Terminal (Programs/Utils/Terminal)
  • Call `hdiutil burn isofile.iso``

hdiutil burns the file to the CD and compares the image file afterwards with the CD.
