Hi all, I'm running MacOS Sierra(non-server) on a Mac Mini mid2011. I just browsed the Apple Store and I noticed that Apple's MacOS Server is very cheap. However, I was curious as to what what makes Apple's MacOS Server special and what unique features it offers over the regular MacOS Sierra non-server version? I checked and even Apple's official website apple.com does not use MacOS Server... Why is this? Thanks!
