Hello Everyone,
I have been using the built in macOS update function to get devices from 10.13.5 to 10.13.6 via Terminal. I figured I could create a policy that uses executes the command
sudo softwareupdate -iaR
in order to pull down the OS upgrade and also whatever is sitting in the App Store in a pending state. For some reason I am having no luck. For reference, this works fine via Terminal as well as pushing out a UNIX command in ARD.
