I used to connect to FICS via Winboard or BabasChess on my Windows machine. But now that I'm on a Mac (specifically on an Intel, Mac OS X Lion 10.7, Macbook Pro 13" Early 2011), these two programs don't just seem to work. Good thing I stumbled upon a comment from one user in the FICS group in Facebook about Raptor Chess.
So when I did install it, it was actually like BabasChess for Mac. So thanks to the developers of this program, now I can enjoy playing at FICS natively on my Mac.
