If you need macOS on the server for whatever reason, your only option is the Mac.

I have four Mac minis racked up for this, with two use cases: 1) iOS CI/CD and 2) some computer vision stuff using Apple’s Vision framework.

No complaints, but I obviously wouldn’t run anything that didn’t need to be on a Mac on these systems.

BTW, you can rack mount twenty Mac minis in the footprint of a single rack mounted Mac Pro (there’s a 1U mount that takes two and they’re small enough to mount on both the front and the back of the rack). So 20 M2 Pros per 5U.

They’re of course not a sysadmin’s dream but they do tend to stay up and Ansible works fine.
