For the users that prefer a GUI Application, you can try Sancho. Download the Mac Version from http://sancho-gui.sourceforge.net/download.phtml

For using it, simply open Sancho AFTER launching the mlnet core.

I've been talking with the developer of Sancho, and it'll be included with the next release of the mlnet core package, that will be released in one or two weeks.

One recomendation for Sancho. You can "link" a core to the GUI in Sancho's prefs. This may be a bad idea, because closing the GUI implies also closing the core.
