    f you already have the "macOS Catalina Beta.App", make sure that you move it to the Application Folder. The next thing you need to do is convert Installer files to an ISO using the Terminal. To launch the Terminal go to "Applications" then "Utilities."

    # Create a DMG Disk Image
    hdiutil create -o /tmp/Catalina -size 7900m -volname Catalina -layout SPUD -fs HFS+J

    # Mount it to your macOS
    hdiutil attach /tmp/Catalina.dmg -noverify -mountpoint /Volumes/Catalina

    # Create macOS Catalina Installer
    sudo /Applications/Install\ macOS\ Catalina\ --volume /Volumes/Catalina --nointeraction

    # Unmount Catalina Disk
    hdiutil detach /volumes/Install\ macOS\ Catalina\ Beta

    # Convert the dmg file to a iso file
    hdiutil convert /tmp/Catalina.dmg -format UDTO -o ~/Desktop/Catalina.cdr

    # Rename and Move to Desktop
    mv ~/Desktop/Catalina.cdr ~/Desktop/Catalina.iso
