Steam Play will be supported
Although console and PC fans are getting giddy for BioShock Infinite's new DLC, Burial at Sea, Mac users are pretty much left in the dust -- until August 29 that is, which is when the Mac version is hitting the market. This new release will include Steam Play support and will also be released on the Mac App Store.
The bad news is the announced price is $60, which is considerably higher than picking up the game through pretty much any other avenue. So as always, make sure you comparison shop! If you want to see if the game will run on your machine, you can use the Mac Match tool here.
