At the Geniusbar they have bootable Mac OS installers and EFI updates on the internal network. And it would be very handy for me to have this available in my own workshop.
I have tried the System Image Utility app and have it create an image on my Synology NAS but that did not work. Besides the fact that I might need a different server. I did not see an opportunity to create images other than the one my iMac is running on.
I contacted JANF but they told me their system doesn’t offer this.
