Cannot connect to Catalyst on Mac OS

Hello,

For the past couple of hours I have been trying to figure out why I cannot get the simple CxxNonOverlappingAMRExample example to run with Live Visualization through Catalyst (I set EnableLiveVisualization to True in the sample script)

The example works fine on Ubuntu, but on my Mac I cannot successfully do the step where I run the program and it connects to the Catalyst (local) server. When I try to connect to localhost on port 22222, I get the following error message:

ERROR: In /Users/ahmad/paraview/VTK/Common/System/vtkSocket.cxx, line 481
vtkClientSocket (0x7fef67b8c7d0): Socket error in call to connect. Permission denied.

ERROR: In /Users/ahmad/paraview/VTK/Common/System/vtkClientSocket.cxx, line 53

vtkSocketCommunicator (0x7fef67b8b030): Can not connect to ahmad.local on port 22223

Version info:
ParaView version: 5.4.1 (64 bit)
Mac OS: 10.12

Cheers, Ahmad
