It's all part of what Valve's calling "The Mac Update" to the colorful multiplayer affair. In addition, those that play Team Fortress 2 on Mac before Monday, June 13 will get a "free limited edition set of in-game earbuds."

Don't be fooled by the naming of "The Mac Update," as everything it brings--short of being able to earn in-game earbuds--is likewise available on Team Fortress 2 PC. In fact, those that already own Team Fortress 2 PC will be able to download it on Mac for free, with both platforms using the same servers so that everyone can play together.
