LNet doesn't work in macOS

[han-k59]

I have an application which works fine in Windows and Linux. but it doesn't work in the Mac (High Sierra). Any idea why? Attached a small test application which can run as Server(host) and Client. Two should communicate with each other but it doesn't work for the Mac.

I will drop the same issue at trevoz#3
