What you say is true about the project but both PyTorch works on Mace and Tensorflow was ported to Macs by Apple

They were originally available only as binaries, have they released the code changes required or upstreamed them yet?

Tensorflow was always on GitHub and PyTorch was in their source tree in their prerelease branch and then mainlined .
