Is there a guide somewhere with a full set of instructions from start to finish for what I would need to do in order to set up a package to allow me to do an unattended in-place macOS upgrade using Casper Remote?
Specifically from OS X 10.10 to OS X 10.11 (a sizable chunk of our equipment cannot go to 10.12 so we don't want to move to that yet).
I'm looking to do this during the summer break but I want to set things up and test it beforehand so I can check a) that it works and b) how much time it takes.
