MacOS doesn't support those, so no matter what you do, you can't run them directly on MacOS. That's why you need a VM, and you need the WSL Windows subsystem for Linux on Windows. BSD has jails, but they don't have the same functionality. In particular, I sorely miss the network namespace that Linux has on MacOS.
