@tcandela You misread the article. The --fetch-full-installer command did not exist in softwareupdate until Catalina, so you can't use it in older version of macOS

@sdagley I had a feeling that was the case; so if i want to run this command it would have to be on a mac running Catalina? but it will put the installer for 10.13.6 or 10.14.6 on the mac running Catalina? then i can grab that installer and use on other computers?

sudo /usr/sbin/softwareupdate --fetch-full-installer --full-installer-version 10.13.6 or 10.14.6

does the startosinstall command exist for earlier macOS? '/Applications/Install macOS Catalina.app/Contents/Resources/startosinstall' ‑‑usage

@tcandela startosinstall is available in the 10.13 and 10.14 installers. BTW, I am a fan of the macOSUpgrade script for upgrades as it does a bit of error checking before attempting the upgrade.
