What is an ISO file

Before we head to download an ISO file, let's figure out what is an ISO file first. ISO file, also known as ISO image, is a disk image that contains everything that would be written to an optical disc, disk sector by disc sector, including the optical disc file system. 

ISO images can be created from an optical disc by disk imaging software, from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format. ISO image is able to be written to an optical disc such as CD, DVD, and Blu-Ray.

The aim of ISO files is to create backups for the optical disc, while ISO files nowadays are used primarily for installer images such as operating systems. The macOS Ventura ISO file is a disk image that contains all the files and folders that are indispensable in the macOS 13 installation. Therefore, you can get the 13 running on VirtualBox and VMWare in an easier manner.

If you have a good understanding of the ISO file now, why not share its definition for more people's reference?

Step 1: Download macOS Ventura 

There are kinds of channels for you to download the macOS Ventura file, but the easiest one is via App Store on your Mac. 

  1. Prepare at least 12GB of free space on your Mac computer. If there is not enough free space or the Mac disk is full, you can free up space on Macintosh HD for the macOS Ventura file download.
  2. Head to App Store via the Spotlight Search shortcut.
  3. Search for macOS Ventura in App Store and find all available downloads there.
  4. Click Get next to the macOS Ventura that you want to download and it will appear under the Software Update section. Download macOS Ventura
  5. When the download ends, navigate to the Applications folder on your Mac to check the macOS Ventura lies there.

Step 2: Create the macOS Ventura ISO file with Terminal

In this section, you will learn how to create the macOS Ventura ISO file on Mac using command lines. All you have to do is copy and paste these command lines into the Terminal window.

1. Create a macOS Ventura.dmg file (Download macOS Ventura DMG?)

You can execute certain command lines to complete this task:sudo hdiutil create -o /tmp/Ventura -size 14000m -volname Ventura -layout SPUD -fs HFS+J

  • Size: the size of the volume that needs to run macOS Ventura, which should range from 14GB to 19 GB.
    Volume name: Venturaiso is the name of the volume. You're recommended to leave it unchanged to avoid any unknown errors.
  • Layout SPUD: it refers to the Single Partition, Apple Partition Map.
  • -fs HFS+: it means the file system option.

2. Mount the macOS Ventura.dmg file

You can open the temporary directory, right-click the macOS Ventura.dmg file, and then mount the macOS Ventura DMG through the graphical interface. 

Or, you can run certain command lines to mount the macOS Ventura DMG file.sudo hdiutil attach /tmp/Ventura.dmg -noverify -mountpoint /Volumes/Ventura

3. Convert the Ventura.dmg file into an installer

  1. Type sudo in the Terminal home window.
  2. Open the Applications folder and control-click the macOS Ventura option.
  3. Choose Show Package Contents in the dropdown menu.
  4. Head to the Contents directory and switch to the Resources tab.
  5. Locate Create Install Media, select it, and then drag it to the Terminal window.
  6. Then, the command line in the Terminal window should be like this:sudo /Applications/Install\ macOS\ Ventura beta.app/Contents/Resources/createinstallmedia
  7. Next, you should add the volume that mounted the Ventura in the Terminal. All you need to do is type in -volume and then drag the mounted disk from the desktop to the Terminal. The final command line should be like this: sudo /Applications/Install\ macOS\ Ventura beta.app/Contents/Resources/createinstallmedia –volume /Volumes/Ventura –nointeraction

 4. Unmount the macOS Ventura installer

Once the installer is created, you have to eject or unmount the disc from your Mac desktop. You can eject it by right-clicking the file on your desktop and selecting Eject.

5. Convert the macOS Ventura.dmg file to the macOS Ventura.cdr file

Provided that we have a macOS Ventura bootable DMG file, we are almost finishing our macOS 13 ISO file creation work. Type the command line below to convert the macOS Ventura.dmg file into a .cdr file first.

hdiutil convert /tmp/Ventura.dmg -format UDTO -o ~/Desktop/Ventura

6. Convert the macOS Ventura.cdr file to an ISO file

The following command line is going to convert macOS Ventura.cdr to an ISO file and then move the macOS Ventura.iso file from the temporary location to your desktop.

mv -v ~/Desktop/Ventura.cdr ~/Desktop/Ventura.iso

Now, you have a macOS Ventura.iso file and you can experience macOS 13 on other operating systems with certain Virtual Machines, for example, VirtualBox, VMWare, and Parallels Desktop.
