Whether the tools are “unixy” is of course an interesting discussion. :p
I guess my line of thought was: kind of “unix” -> kind of “posix” -> kind of compatible with a lot of your familiar tooling.
All this equals pretty good platform for many nerds.
I could have made myself more clear.
Macos can use the xhyve hypervisor (bhyve port) which again points to “unixy” roots — it runs freebsd for example.
Through the years I spent quite some time hacking about to get bsd running on other hypervisors, and for the longest of time it was just a hassle with abysmal performance (vmware esx, xen/xenserver).
Docker on osx is by the way completely seamless from a UX perspective.
As a mobile/laptop dev experience I still think the new air is great. ;)
macOS is its own thing, where some functionality is provided by some very old versions of BSD tools. But using it feels pretty different from using a modern BSD variant.
