It's not that simple.

The Linux nbd-client program doesn't actually speak the NBD protocol; it
does the handshake, and then hands the connected socket to the kernel.
It is then the kernel which implements the NBD protocol, using the
already set up socket from user space.

If you're going to port NBD to macOS (which would be awesome!), you'll
need to do something in kernel space to mirror the Linux nbd.ko module.
To the best of my knowledge, nobody has done the necessary work for now,
so you'll have your work cut out for you.

Should you wish to take on this challenge, note that the NBD protocol
documentation is at
<https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md>.

Kind regards,
