The Linux Lobby does not work for macs. Does any one know of any mac beta lobbies? How do you get the lobby to work for mac?

It does work. Somewhat. I managed to cross compile SpringLobby for OSX 10.4 from ubuntu and others have managed to build it natively too.
Problem is you'll need a working (and current) spring build too and SpringLobby will have to load the produced unitsync lib. That's the point where we're currently struggling with.

edit: that's what i produced from cross compile, no idea if it's actually runnable. i don't own a mac

Does it need to be in a specific place to work or be with specific files.

you need wxwidgets installed
