Looking for a way to burn an ISO image file to a CD or DVD on your Mac? Luckily, just as you can mount and burn ISO images files in Windows 8/10 without additional software, you can also do the same thing in OS X.
There are a couple of different ways you can burn an ISO image in OS X and it really depends on what version you have installed. For the last several years, you could use Disk Utility to mount the ISO image and then burn it to a disc.
However, with the latest release of OS X, 10.11 El Capitan, Apple has removed the burning functionality from Disk Utility. You can still burn ISO images in El Capitan, but you have to use Finder instead. The Finder method also works on older versions of OS X too.
Lastly, you can use Terminal and the hdiutil command to burn an ISO image to disc if you are comfortable using that tool. In this article, I’ll show you all three methods for burning ISO images in OS X.
Finder Method
The Finder method is now the most universal method for burning ISO images in OS X since it’s supported on pretty much all versions. It’s also extremely easy to do. First, open a new Finder window, navigate to the location of your ISO file and then single click on it to select it.
Having an Intel CPU is the easiest way to run a Mac OS X virtual machine. That is because Mac computers and laptops use Intel CPUs exclusively, and therefore the virtualization is straightforward, from a technical point of view. Download the macOS High Sierra image. So, we have to download the Intel version of the Mac OS X virtual machine. You know you're dealing with one of these archives when you see the.iso file extension. ISO images can be burned to CD or DVD for use on other computers or sharing with others. You can also use ISO images with virtualization applications like VMware Fusion or Parallels Desktop. Here's how to burn an ISO disc image on your Mac.
Now go ahead and click on File and click on Burn Disk Image at the bottom of the list.
If you don’t already have a disc in your drive, you’ll be asked to insert one. Then just click the Burn button to start the burn process.
Another quick way to burn the ISO image file is to just right-click on the file and choose Burn Disk Image. As long as you have a disc in the drive, the burn process will start immediately.
Disk Utility Method
If you are running OS X 10.10 or lower, you can also use the Disk Utility method to burn your ISO image. Open Disk Utility by clicking on the Spotlight icon (magnifying glass) at the top right of your screen and type in disk utility.
Now click on File and then Open Disk Image.
The ISO image will show up in the left-hand side along with the list of hard drives, etc. Click on the ISO file and then click on the Burn button at the top.
Pop your disc into the drive and click the Burn button to start the process. As mentioned earlier, this no longer works on OS X 10.11 El Capitan.
Terminal Method
Lastly, if you love using the Terminal, you can type a simple command to burn the ISO image file.
I would suggest copying the file to an easy location like your desktop and renaming the file to something short too. In my case, I copied the file to my desktop and renamed it to just ubuntu.iso. I navigated to the desktop by typing in CD Desktop and then typed in hdiutil burn ubuntu.iso.
If you have a disc in the drive before you run the command, the burn process will start automatically. Otherwise, it’ll ask you to insert a disc. Those are all the ways you can burn your ISO image on a Mac without third-party software! If you have any questions, feel free to comment. Enjoy!
On This Page:
The instructions below are specific to the Disk Utility program available on the Mac OSX Operating System on the Macintosh computers in IT Computer Classrooms. Even if your computer has a different version of Mac OS X, these instructions should provide a general guide for completing this process. Refer to the documentation provided with your Mac operating system software if you need more specific information.
Burn a DMG or ISO File to Disk
After you have downloaded a program's installation file (*.dmg format for a Mac-compatible program, *.iso format for a Windows-compatible program) to a Macintosh computer's hard drive, you can burn this *.dmg or *.iso file to a blank CD or DVD. You can use this disk to install the program on another computer, or have a backup installation disk in case you need to reinstall the program in the future. You can use a Mac to burn an *.iso file to a disk, and the resulting installation disk will run properly on a Windows computer.

Note: For .dmg or .iso files that are larger than 4.7 GB, you will need to use dual layer DVD. See About Recordable Media Types for more information about different types of recordable DVDs.
To burn a DMG or ISO File to disk:
- Start Applications > Utilities > Disk Utility. The Disk Utility window will open. The Mac's available drives (e.g., hard drive partitions, CD/DVD drive) will be listed by name in the left pane.
- Insert a blank CD or DVD disc into the Mac CD/DVD drive. Note: If the CD is blank, the You inserted a blank CD pop-up window will appear. Select Action > Open Disk Utility, then click OK. The Disk Utility (a.k.a. SuperDrive) window will reappear.
- Drag the *.dmg or *.iso file from a Finder window or the desktop to the Disk Utility window, and drop it in the left pane in the empty area below the Mac drive names. The *.dmg or *.iso file name will display in the left pane of the Disk Utility.
Note: You can drag and drop multiple files to the Disk Utility. - Select the *.dmg or *.iso name in the left pane of the Disk Utility, then click Burn (top left). The Burn Disc In: window will open and display the destination (your blank CD/DVD) for your file.
- In the Burn Disc In: window, click Burn. The Disk Utility Progress window will open and the burning process will begin.
- When the burning is complete, the disk is ejected from the drive and the Disk Utility Progress window displays a message that the image burned successfully. Click OK. The Disk Utility Progress window will close.
You can now close the Disk Utility and use your installation disk.
About Recordable Media Types
There are two types of recordable CDs and DVDs: CDs and DVDs labeled 'R' can only be recorded on once, while those labeled 'RW' allow you to write data to them once and then add more files later. You can also erase the data on CD-RW or DVD-RW disks entirely and re-use them, which you can't do with DVD/CD-Rs. You can use either kind in IT Computer Classrooms.
For dmg or *.iso files that are larger than 4.7 GB, you will need to use dual layer DVD.
