I find it dubious that a technical person claims to "just bought a new Mac mini to properly tinker with claws over the weekend". Like can they not just play with it on an old laptop lying around? A virtual machine? Or why did they not buy a Pi instead? Openclaw works with linux so not sure how this whole Mac mini cliche even started, obviously an overkill for something that only relays api calls.

Using a Mac Mini allows for better integration with existing Apple services. For many users, that just makes sense.

Exactly, especially iMessage. It's fair to think that's not worth it, but for those who choose to use it, it is.

As a long time computer hobbyist who grew up in MSDOS and now resides in Linux I'm starting to wonder if I am not more connected to computing than a lot of people employed in the field.

Your suspicions are correct, any extra machine works: 4GB Pi, virtual machine, or old laptop.

There's the issue.
