How To Create Bootable ISO Image On Mac OS X

Its been a year that I have using Mac, but I never actually felt the need to create bootable ISO Image. But lately, I needed to install Red Hat on my Windows desktop, then I wanted to make a Windows compatible bootable ISO on my Mac, and that is when I went through few videos and tutorials to get it done.

Now since I have created Bootable ISO image on Mac OS X, I would be sharing the complete tutorial to get it done. The thing about Mac that’s fascinating is the fact that it does not need any third party tool for most of your requirements.

So, in this tutorial, I would be using the Disk Utility and the Terminal to get the job done. Below is the complete step by step guide.

How To Create Bootable ISO Image On Mac OS X

  • I am assuming that you have the contents (that have to burnt as ISO image) in a DVD or CD. So just insert it into the ROM
  • Now, launch Disk Utility which can be found in Utilities folder of Applications
  • On the left panel of Disk Utility you will be able to see your DVD, so just click (single click) on it
  • Now navigate as File > New > Disk Image from “<name_of_dvd>”…

  • Insert the empty DVD, and when the finder detects it, choose the action as Open other application, choose Disk Utility and open it
  • Once the Utility opens, drag and drop the required ISO image onto the left panel of the tool
