I have the same problem.

#652 seems to imply Rust code should work. In my experience it doesn't even compile.

Did you try following the Mac OS instructions for fuser?

https://github.com/cberner/fuser

If that works, we can add that to the encfs readme.

Yes I did - no it does not work. As I said, FUSE is installed, the problem is that fuser fails to locate its library. And there doesn't seem to be a way to tell it... See cberner/fuser#450 (does not have any replies so far).

@vgough Want to add one thing: when I close the https://github.com/cberner/fuser.git repo (using master branch) and build it locally - it builds OK and passes all the tests. Which probably means - something is wrong with how encfs tries to "custom-build" it. Because "stanalone" cberner/fuser finds libfuse2.dylib perfectly, and accesses it fine during its integration tests.
