Polish video game developer CD Projekt is here at the MacTech Conference in Los Angeles this week, because they're making a few big announcements today about the Mac platform. First, the company's biggest and most popular game, The Witcher 2, is finally arriving on the Mac platform. The Mac version was announced earlier this year, but it's now available -- if you're interested in playing the award-winning and critically acclaimed RPG, you can pick it up on the company's website right now, or grab it over on Steam. It's arriving with a Mac launch sale for just $29.99.
