Maybe podman “just works” on Linux but it still has some work to be done before the same could be said for macOS.

E.g. https://github.com/containers/libpod/issues/4039#issuecommen...

Ultimately Docker on macOS is just Docker on Linux in a VM over TCP (and it’s not open source.)

To be less nebulous: regarding the problem of being “rootless,” macOS support is neither here nor there. As far as I can tell it doesn’t really matter since the containers are already in a VM anyways.
