I've tried downloading the binaries, and successfully started gfsh, but when I try to start locator or server, the cli just stays forever trying to finalize the startup, adding points to the "progress bar"...like this:
Starting a Geode Server in /Users/sezcurra/geode/march-powerful-kite...
.......................................................................
..............................<and goes on for ever>
Probably the answer is that it does not run on MAC OSX...
