Step 2. Create Your Own macOS Sonoma ISO File with Terminal

Now that you have the macOS Sonoma full installer, let’s move on to how to create a macOS Sonoma ISO file using Terminal.

1. Open Terminal via Spotlight.

2. Paste the command below into Terminal and press Enter.

   hdiutil create -o /tmp/Sonoma -size 16384m -volname Sonoma -layout SPUD -fs HFS+J

   Note: This command will create an empty disk on your Mac.

   

3. When a disk is created, run the command below in the Terminal window.

   hdiutil attach /tmp/Sonoma.dmg -noverify -mountpoint /Volumes/Sonoma

   Note: This command will mount your created disk.

   

4. Execute the following command in the Terminal and enter your administrator password.

   sudo /Applications/Install\ macOS\ Sonoma.app/Contents/Resources/createinstallmedia --volume /Volumes/Sonoma --nointeraction

   Note: This command will create your installation media. If your macOS Sonoma installer is not named Install macOS Sonoma.app, replace it with the actual name, and don't forget to use the backslashes (\) to escape the space characters.

   

5. Continue to run the command below.

   hdiutil eject -force /Volumes/Install\ macOS\ Sonoma

   Note: This command will unmount your disk image.

   

6. Run the command below.

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

   Note: This command will create a CDR file.

   

7. Continue to run the command below:

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

   Note: This will convert your CDR file to ISO format.

   

8. Finally, run the rm command to clean up the files.

   rm -fv /tmp/Sonoma.dmg

   

   Once everything is done, you will find a file named Sonoma.iso on your desktop. Now you can use it to clean install macOS, upgrade your Mac, and run macOS Sonoma on a Windows PC using VMware or VirtualBox.

The Bottom Line

Hopefully, you have successfully downloaded or created your desired macOS Sonoma ISO file for virtual machine tools like VMware and VirtualBox.
