Complaints about the game, patch (or lack there-of), and editor (or lack there-of) should most likely be directed to MacSoft who sold you the game, not Firaxis or Brad (who, as others have mentioned, kicks major booty for doing what he's doing). They are the ones that published the Mac version, collect the money from the sale of the game, and who are (or rather should be) providing support and who contracted Westlake to do the programming (whom Brad has/is working for).
Perhaps if more of us make it clear to the publisher(s) that we'd really prefer to get our same money's worth out of a game as our Win-brethern, we might start to see some changes in this area. But who am I to talk... I'm just a non-gamer (by definition since I own a Mac, see) who won't be able to resist giving Bioware their $50 for NWN and getting 1/2 a product in return.
OK, so I'm bitter this week after seeing the NWN toolset... sigh
