A friend bought a 1U MacOS Server machine for work. It was nice, but the fans were very loud. He said all kinds of simple yet important things related to account permissions, IIRC, would break whenever he updated the OS. It was as if they had done no testing at all before rolling it out.

As you say, they've got no excuse. But it shows that they continue to not really care about macOS.

Cheers,
Scott.
