LightFICS is the Lightweight Solution for FreeChess.org (FICS) App for Mac
If there’s Raptor, a great FICS desktop client for Mac, for advanced users, fortunately, there’s LightFICS for newbies. What’s more, apparently it’s lightweight from all the bells and whistles. You pretty much have to log in and play.
The app actually looks promising, although personally, I still have to try it out. Moreover, I liked the brown and cream squares color combination for the chess board.
