Munki is great. It keeps your macs up to date - well it does most of the time. Sometimes you get a user that just refuses to click on “Update” now matter how many times it pops up. Now you have a tool to defeat them - install this package over ARD and munki will install everything that’s available, including Apple software updates (it will reboot the mac if needed and carry on where it left off).
I wish I could take credit for all this amazingness, but I just wrapped it up into a package. The source is over at GitHub, and there’s a pre built package as well.
