How to open ISO files on Mac

If you’re looking to open a Mac OS ISO file, we have several solutions for you. Learn how to open ISO file on Mac using Disk Utility, Terminal, and an ISO file reader for Mac.

ISO Files on Mac

An ISO file is an exact copy of the data from a physical disc such as a CD, DVD, or Blu-Ray, including its file structure. It serves as a convenient way to store and distribute large volumes of files or media like movies and games.

Since an ISO file behaves like a physical disc, you need specialized software or utilities to “mount” it as a virtual disk drive on your Mac. Here are three methods, to learn how to open ISO files on Mac device.

How to Open ISO Files on Mac OS

Here are the steps how to open ISO files on Mac OS using Disk Utility:

  • Open Disk Utility: Launch Disk Utility from the “Utilities” folder within your “Applications” folder. Alternatively, use Spotlight Search (Command + Space) to locate and open Disk Utility quickly.
  • Click on “File” in Disk Utility: Once Disk Utility is open, navigate to the top menu and click on “File.”
  • Select “Open Disk Image…”: From the drop-down menu that appears when you click on “File,” choose “Open Disk Image…”
  • Navigate to the ISO File: Locate the ISO file you wish to mount in the file selection window, then click “Open.”
  • Mount the ISO File: Disk Utility will now mount the ISO file. You will see a virtual disk icon appear on your desktop and in the Finder sidebar.
  • Access the Mounted ISO File: Once mounted, you can access the contents of the ISO file just like any other drive on your Mac.

How to open ISO files on Mac via Terminal

To open ISO in Mac using Terminal on your Mac, follow these steps:

  1. Save the destination mount point for later use. You’ll need it to unmount the disk.

When you’re finished with the ISO file, use this command to unmount it:
bash

hdiutil unmount /Volumes/your_mount_point

That’s how you can easily manage ISO files using Terminal on your Mac.

Why Use ISO Files?

ISO files are invaluable for managing large datasets, offering more than just storage capabilities. Here are several reasons why ISO files have become increasingly prevalent:

  • Portability: ISO files provide a convenient method to store and share large amounts of data. Whether distributing software, sharing multimedia, or archiving files, ISO files allow carrying entire disc contents without physical media.
  • Universal Compatibility: Following the ISO9660 standard ensures ISO files are universally compatible across different operating systems. They guarantee seamless access and readability on Windows, Mac, Linux, and other platforms.
  • Efficient Software Distribution: ISO files streamline software distribution. Applications packaged in ISO format simplify installation directly from the file, eliminating the need for physical discs or complex setups.
  • Operating System Deployment: Creating bootable USB drives or DVDs from ISO files simplifies OS installations, ideal for system administrators managing multiple devices.
  • Data Preservation: ISO files preserve content and structure from old or rare optical discs, ensuring long-term accessibility and archival in a digital format.
  • Backup Versatility: ISO files are versatile for backups, whether for software installations, personal files, or entire systems, providing compact and organized data storage.
  • Reduced Physical Media Dependency: Using ISO files reduces reliance on CDs or DVDs, contributing to environmental sustainability and simplifying data management.
  • Streamlined Virtualization: ISO files are integral in virtualization, enabling virtual machines to mount images for software or OS installations without physical media.
  • Space Efficiency and Compression: ISO files support compression for efficient storage and distribution without compromising data integrity, making them practical for managing large datasets.

Whether using Disk Utility for a straightforward approach, Terminal for more advanced users seeking command-line control, or third-party software like Commander One for enhanced file management, Mac users have versatile options to mount and access ISO files seamlessly. 

These methods ensure that regardless of the task—whether it’s installing software, managing large data sets, or creating bootable media—Mac users can efficiently handle ISO files with ease and reliability.

FAQs

Does macOS have an ISO?

Yes, macOS does support ISO files, which are commonly used to replicate optical media such as CDs or DVDs. Unlike DMG files, which are specific to Macs, ISO files are universally readable on both Windows PCs and Mac computers. Therefore, if you intend to install macOS Ventura on a virtual machine that is not a Mac, you will need to use an ISO file format.

Does Apple have ISO?

Yes, Apple holds ISO 14001 certification. Apple certifies its manufacturing facility located in Cork, Ireland, with ISO 14001, ensuring that the entire facility adheres to environmental management standards. The complete certification details can be found in the appendix of Apple’s 2024 Environmental Progress Report (PDF).
