How Do I use the Logitech G600 mouse with my Macbook pro? How do I make all the buttons work, how do I configure different modes on this gaming mouse?

I've tried steermouse but that did no good for me? Any help with this will be awesome, I plan on using it for my mac's Guild wars 2.

P.S I run Mountain Lion 10.8.2

Thanks
Personally, I stopped using the Logitech drivers with my Logitech mouse and installed USBOverdrive instead. It's a great USB driver that gives you total control over all the buttons on your mouse.

Any button can be linked to all sorts of system functions, keys, scripts, etc.
