I ran across this article that says you can create a package that will do all the firmware updates. http://www.amsys.co.uk/2017/09/deploying-firmware-updates-imaging/
I am wondering if this works. If so, could I then create a "master high Sierra image" with DeployStudio and set this package to run on reboot.
Anyone tried this??
Looking for a solution for installing High Sierra a we are not allowed to use Apple Push on our network so imaging with Casper Imaging is not possible.
