Last night on the 6th June 2022, at the Apple WWDC event, Apple announced iOS 16, iPad OS 16, macOS Ventura, watchOS 9, and M2 MacBook Air. Since Apple has introduced a newer desktop operating system for the users, also known as MacOS Ventura Windows users are seeking to test it on their virtual machine. So the fastest way is to install it through the ISO image on a Virtual machine. But if you do not have access to an ISO image of MacOS Ventura, you must create it on your own. And the steps to create a MacOS Ventura ISO image or mentioned below. Hope you enjoy it.
How to Create macOS Ventura ISO Image?
Step 1. Download macOS Ventura App
In order to create a MacOS Ventura ISO image, the first step is to download the MacOS Ventura app. Not the macOS Ventura installer, not the DMG file but the application. What do I mean by macOS Ventura app, it means that it should be available within the applications directory just like the other apps are available there. There are a couple of methods that you can use to get the MacOS Ventura, but however, the method that I recommend is the MacOS installer package.
Note: Download the macOS Ventura from the App Store, if it is not there use the below method to get the macOS Ventura App.
If you are part of the developer program of Apple, then you have access to the MacOS Ventura installer package. But for now, you can use the below link to get the MacOS Ventura installer package for free. After downloading the package installer, you have to install it on your Mac. Now the installer is going to ad the macOS Ventura installer into the application directory, you don’t have to join the developer program apple.
Step 2. Create a DMG File
The size of the macOS Ventura is around 10.9 GB and in order to create an ISO file of the MacOS Ventura, you need at least 16GB. But you can experiment with it and you can decrease the amount of storage from 16 should be up to 13 GB. Just on the safe side and to avoid errors I am taking 16GB but you can experiment and decrease the size.
To be clear right now you have to launch the terminal and execute the below command.
sudo hdiutil create -o /tmp/Ventura -size 14000m -volname Ventura -layout SPUD -fs HFS+J- -o /tmp/Ventura: The location is in the Temporary folder on your mac and the dmg file is called Ventura.
- Size: 16384 MB = to 16 GB
Step 2. Mount Ventura dmg file
You can simply open the temporary directory right-click on the Ventura.dmg and mount DMG through the graphical interface or type the below command and it is going to mount it.
sudo hdiutil attach /tmp/Ventura.dmg -noverify -mountpoint /Volumes/VenturaStep 3. Convert the DMG file to an Installer
Convert the Ventura dmg file to a bootable Installer by executing the below command.
sudo /Applications/Install\ macOS\ 13\ beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Ventura --nointeraction
Please keep in mind that many users are facing errors in this step because of not specifying the path of the MacOS installer. I will guide you using the graphical user interface in case you could not fix the errors.
In the Terminal type sudo and leave it there.
Open the Applications directory> right-click on the macOS Ventura App and choose “Show Package Contents“. After that go to the Contents directory> Resources> Find the Create Install Media there, select it, and drag it onto the Terminal.
till here the command looks like this:
sudo /Applications/Install\ macOS\ Ventura beta.app/Contents/Resources/createinstallmedia
Now Path is mentioned very clearly> the next step is to mention the mounted Volume of Venture. So, type –volume and drag the mounted disk from the desktop into the Terminal.
The final command looks like this: sudo /Applications/Install\ macOS\ Ventura beta.app/Contents/Resources/createinstallmedia –volume /Volumes/Ventura –nointeraction
Step 4. Unmount the Ventura
Once the above command is executed, you have to eject or unmount the disc from your desktop. You can also eject it by right-clicking on the file on your desktop and simply selecting eject or executing the below command in Terminal.
hdiutil eject -force /Volumes/Install\ macOS\ 13\ betaStep 5. Convert the Venture.dmg to Venture.cdr
Until now we can say that we have a bootable DMG file of MacOS Ventura, however, we need to convert it to an ISO file. First, we have to convert it to CDR extension and then to an iso image. So type the below command in the terminal.
hdiutil convert /tmp/Ventura.dmg -format UDTO -o ~/Desktop/VenturaStep 6. Move and Rename the Ventura.cdr
For the final step, you have to execute the below command which is going to convert the Ventura.cdr to Venture.iso. Then it is going to move the Venture.iso from the temporary location to the Desktop.
mv -v ~/Desktop/Ventura.cdr ~/Desktop/Ventura.iso
Look at the Terminal:

Conclusion:
In any case, these are the steps that you can use to create a MacOS Ventura ISO image on your MacOS or on a virtual machine. Now, these steps of creating a MacOS Ventura ISO image can be a bit confusing that’s why I also recorded a video of how to create a macOS Monterey ISO image on MacOS Big Sur. This video is really going to help you with the steps. Because all the steps are the same.
