How Do I Burn an ISO File to a Disc on a Mac?


Every now and then you will have a so-called ISO file downloaded and are told to burn it to a disc. But, what is an ISO file and how do you burn it to a CD or DVD on a Mac?

An ISO file, in very simple words, is nothing more or less than an exact bit-by-bit image of a CD or DVD.

Getting such an image onto a CD or DVD on a Mac is very simple, once you know how.

Do I need Addtional Software?

Do you need additional Software? By no means! You own a Mac after all, don’t you? And Apple made sure that most daily tasks on a Mac can be done without needing any additional software. If you were working on a Windows XP computer, you’d have to download a tool like ISOBurner first.

To burn an ISO onto a CD or DVD on a Mac you will use the ‘Disk Utility’ which is already installed and ready for you to use.

Step By Step Instructions

  1. Open Finder
  2. Navigate to Applications
  3. Navigate into the folder labeled ‘Utilities’
  4. Find the application named ‘Disk Utility’ and start it
  5. At the top of the Disk Utility you will see a button that looks like a ‘Nuclear Waste Warning’ sign, labeled ‘Burn’. Click this button.
  6. Select the ISO when prompted to. 
  7. Insert an empty disc

That is all there is to it.


Burning a disc image file to a CD or DVD on a Mac is very easy and you don’t even need additional software to complete the task.
