I managed to get SSHFS working on Mac w/o using macFuse, by using Docker as an intermediate and connecting it to the Mac via a Samba share.

Performance seems okay.

I was mostly curious if it could be done, but also would rather not install custom kexts.

The README needs some work... I just put it together.

Biggest struggle I had was getting r/w access, and not just read-only.
