The Proton C++ binding is supported on MacOS and our CI does indeed test it there.
The Qpid broker relies on a threading abstraction that can be changed to target different platforms. Using modern C++ this abstraction should now use the standard C++ library threading primitives for maximum portability. However the existing code was written pre C++11 and, as Robbie has pointed out, has been very lightly maintained since. It wouldn't be very hard to change this code for C++ cross platform portable code.
