As someone who has worked with Apple "Enterprise" / "Business" / "Pro" products before..... I'll wait. It will start half decent, get a push to 90% of everything you need and then slowly get rewritten simplified to a level that is too basic to do any real work or just abandoned.

Yeah no. There was a time (early 2000s) when Apple made half-decent server hardware and operating systems. Those days are over. Apple has vocally abandoned the server market, and trying to use MacOS as a server today is an exercise in futility. Too many things require the GUI, and Apple's intense focus on security theater makes everyday server operations a nightmare.

I'm not talking about macos.. I'm talking about becoming an energy efficient cloud vm provider.

What is the criteria to meet energy efficient?

What's an example of something that requires the GUI?

Allowing full-disk access, turning on sshd, repeatedly clicking "OK" when you're asked "Do you want <freshly-compiled yet unsigned app> to accept incoming connections?"

If there are CLI ways to do this stuff I'd love to hear them.

I think there probably are.

I know sshd is controlled through systemsetup[1].

    sudo systemsetup -setremotelogin on
