Even when it was at its most active, there was apparently not much
developer interest in supporting the qpid-cpp broker running on MacOS
(or accompanying Qpid::Messaging cpp client), with a concentration of
interest on Linux. A look at the qpid-cpp repository would show that
qpid-cpp is largely stagnant these days, so I doubt there will be much
traction on the MacOS subject now either. The old mailing list posts
would be your main avenue to any specifics.
C++ client wise specifically, attention also shifted away from the old
Qpid::Messaging C++ client to the Qpid Proton C++ binding many years
ago. Proton does compile on MacOS, I believe it possibly uses libuv
there (in contrast to typical Linux usage), which might be how it
works at all...though again I think it would be fair to say the bulk
of dev interest is around Linux.
