In commemoration of Mac owners getting the game and PC owners getting the update, Valve has briefly discounted the multiplayer shooter by 66%, making it $6.80.

As with Valve's other Steam for Mac releases, those that already own the game on Steam for PC will be able to download a free copy of the Mac version, with those that buy the game getting both versions for the price of one. Additionally, Counter-Strike: Source supports cross-platform play, enabling PC and Mac gamers to play together.

As for the changes the update brings, look no further than below:

Updates to Counter-Strike: Source have been released and the game is now available on the Mac. To celebrate this update, Counter-Strike: Source will be on sale for 66% off until Friday.
