Are there any publicly accessible Unixes these days?

I don’t know. Certified Unix? There might be, but it would certainly be a small picking. This is the list of UNIX certified products: https://www.opengroup.org/openbrand/register/.

I did not realize that macOS was officially certified Unix. Interesting, thanks. I guess that makes my laptop a multi-user Unix.
