How to Mount ISO on Mac: A Beginners’ Guide

Hello and welcome, fellow Mac users! Have you ever come across an ISO file and wondered how to mount it on your Mac? Well, look no further because we are here to guide you through the process step-by-step. With just a few simple clicks, you’ll be able to access the contents of your ISO file on your Mac in no time. So let’s get started!


Step 1: Download a Disc Image Mounter

The first step to mounting an ISO file on your Mac is to download a third-party disc image mounter. We recommend using either “Mounty for NTFS” or “Apple Disk Image.” Once you’ve downloaded and installed either one of these applications, you’ll be ready to start mounting your ISO files.

Step 2: Right-click on the ISO file

Once you have a disc image mounter installed, find the ISO file you wish to mount and right-click on it. A menu will appear with several options.

Step 3: Select “Open With”

From the menu, select “Open With.” Another menu will appear with a list of compatible applications.

Step 4: Choose your disc image mounter

Choose the disc image mounter you downloaded in step one from the list of compatible applications. Your ISO file will begin mounting immediately.

Step 5: Wait for the ISO to mount

It may take a few moments for the ISO to fully mount on your Mac, so be patient and wait for the process to complete.

Step 6: Access the files in your ISO

Once the ISO has mounted, navigate to the disk image in Finder and double-click on it. You should now have access to the contents of your ISO.

Step 7: Use the files as normal

You can now use the files in your ISO just as you would any other files on your Mac. Edit, copy, or move them as needed.

Step 8: Unmount the ISO

When you are finished using the files in your ISO, it’s important to unmount the disk image to avoid any potential issues. To do this, simply right-click on the mounted ISO and select “Eject.”

Step 9: Delete the ISO file

Once you’ve unmounted the ISO file, you can delete the original ISO file if you no longer need it.

Step 10: Repeat for additional ISO files

To mount additional ISO files, simply repeat steps 2-9 for each file.

Step 11: Consider creating a shortcut

If you frequently mount ISO files on your Mac, you may want to consider creating a shortcut to your disc image mounter application for easier access.

Step 12: Familiarize yourself with other disc image formats

Finally, it’s important to note that there are several other disc image formats besides ISO, such as DMG and IMG. Familiarize yourself with these formats in case you encounter them in the future.


Now that we’ve gone through the steps, let’s take a closer look at what’s happening and why each step is important.

First, we recommend downloading a third-party disc image mounter because it provides more options and features than the built-in macOS disc image mounter.

When you right-click on the ISO file, you will see several options including “Open With.” This lets you choose which application you want to use to open the file.

Choosing your disc image mounter from the list of compatible applications tells your Mac to use that application to mount the ISO file.

Once the ISO file is mounted, it acts as a virtual disk and can be accessed and used just like a physical disk.

It’s important to unmount the ISO file before deleting it to avoid any potential issues with the contents of the file.

Creating a shortcut to your disc image mounter application can save you time and make it easier to mount ISO files in the future.

And finally, familiarizing yourself with other disc image formats can be helpful because not all disc images are in ISO format.

Tips and Tricks

Tip 1: Rename the ISO files

If you frequently use ISO files, consider renaming them to something more descriptive to make it easier to find the one you need.

Tip 2: Use a virtual CD/DVD drive

Using a virtual CD/DVD drive, such as “Virtual CD/DVD-ROM Utility,” can give you more flexibility when working with ISO files.

Tip 3: Consider using a cloud-based storage solution

Uploading your ISO files to a cloud-based storage solution, such as Google Drive or Dropbox, can make it easy to access them from any device.

Tip 4: Check the MD5 checksum

Before using an ISO file, it’s a good idea to verify its authenticity by checking the MD5 checksum.

Tip 5: Use a disc burning program

If you need to burn the contents of an ISO file to a physical disc, consider using a disc burning program, such as “Burn for Mac.”

Tip 6: Use a password-protected ISO

If you need to share sensitive data in an ISO file, consider using a password-protected ISO for added security.

Tip 7: Use a multi-session ISO

If you need to add or remove files to an ISO file, consider using a multi-session ISO to make the process easier.

Tip 8: Use a compression program

If you need to reduce the file size of an ISO, consider using a compression program, such as “The Unarchiver.”

Tip 9: Use a file conversion program

If you encounter a disc image format that is not compatible with your disc image mounter, consider using a file conversion program, such as “DMGConverter.”

Tip 10: Backup your ISO files

Finally, it’s important to regularly backup your ISO files to avoid data loss if something happens to your device.

With these tips and tricks, you’ll be a pro at working with ISO files on your Mac in no time. Happy mounting!
