What is an ISO file?

An ISO file is a complete data rendering of a physical disc of storage such as a CD, DVD, or Blu-Ray. An ISO file for Mac OS X includes all the data on a disc, as well as the file structure just as it is on the physical storage. ISO files are usually used for storing and distributing big file volumes or media like films and games. Because the file functions the same as a disk, you need a piece of software or utility to open an ISO file on Mac that can “mount” the file as if it was a disk drive. So let’s look at three methods you can employ to easily mount ISO files on a Mac device.

How to open an ISO file on Mac using Disk Utility

From the dock, click on Finder and go to the sidebar’s “Applications” menu. Enter the folder titled “Utilities” and double-click on “Disk Utility”. Once the program is open, go to the menu bar above and click on the “File” tab can click “Open Disk Image”. Then just choose the .ISO file on Mac that you want to mount and press “Open”.

How to open an ISO file on Mac via Terminal

You can use Terminal commands to open an ISO file in Mac, but first you need to save the destination mount point so that you can unmount the disk. So with this information, input the following command to mount the ISO file: hdiutil mount ~/(-path to your ISO file-)/filename.iso

When you’re done with the ISO, unmount it with this command: hdiutil unmount /Volumes/(-your mount point-). That’s all there is to it.
