Good news everyone! I just played the Mac version of The Final Station and it works like a charm. I tested it on a Retina MacBook Pro 15", an older 13" MacBook Pro with integrated graphics and a 12" MacBook, all running El Capitain. Let's just say if you play games on the 12" fanless MacBook you're going to have a baaad time. It overheats when playing games. So it'll work on most latest and last generation Mac hardware. Just keep in mind that the Mac version won't have Steam-features as we don't have enough time to properly test those. Those will come post-launch. Same for Linux -- we can't properly test it in just a few days, and need to integrate Localization before launch. Just setting expectations here! That said, the pre-orders are live and kicking! With the way the discounts work, you can get the Collector's Edition for under the retail price of the normal game. That's a sweet deal, considering it has the highly immersive and atmospheric OST, and a cool artbook. http://store.steampowered.com/app/435530 Pre-purchase the Collector's Edition here: http://store.steampowered.com/bundle/1330/
