I have ported the Java Cluster Manager Console for VCS to MacOS.  Download hagui.tar.gz using the link below and expand this tar ball as root under / on your MacOS box.  Execute /opt/VRTSvcs/bin/hagui as a non-root user to start the GUI.

* - This software is being provided "as-is".  The Java Cluster Manager Console for VCS is not officially supported on MacOS.
