If you ask about Apple OS X games on /v/, you're going to get drowned in trolls. We'd like to apologize for that: sorry.
Damn near every major game made for Microsoft Windows also has an OS X version these days, so check that out until we can get /v/ to give a straight answer, and write this page.
For games from before OS X came out, check the Macintosh page.
And for God's sake, get Steam. It's been available for OS X since May 2010.
Also, Unix and Mac users should look into Wine. It usually supports Windows games and it's free.
By the way, it's pronounced "o-s-ten". Yeah, the X is a 10, roman numerals n' shit. Also, it's no longer called "Mac OS X" since 10.8.

|Bioshock||FPS||2007||Adventure in the underwater dystopia of "Rapture," what was supposed to be a libertarian paradise. Action / exploration and customizing combat. There's some moral ambiguity too, when it comes time to decide what to do about the "little sisters."||Feral|

|Dust: An Elysian Tail||Platformer / Action-RPG||2013||A mysterious warrior wanders a fantasy land with a magical talking sword and a little flying sprite companion, trying to regain his own memories.

|Giana Sisters||Platformer||2011||Remake/reboot/reimagining/rewhatever of the fondly remembered German Super Mario ripoff. A solid, very charming old-school platformer. Also for DS, iOS, and Android.||App Store|
|Half-Life Complete||FPS||2008||An experiment goes terribly wrong, and everyone's favorite crowbar-wielding MIT Ph.D. has to deal with a ton of aliens invading and the black ops trying to cover up the whole mess. Come on, it's the goddamn Half-Life series, you can't not play this!||Steam|
|Heroes of Newerth||MOBA||2010||A Defence Of The Ancients clone.||Freemium:|
|Katawa Shoujo||Visual Novel||2012||Freeware romance VN with roots on 4chan.||Free:|
|Machinarium||Puzzle||2009||The black-hat robots stole your robot girlfriend, and threw you on the robot junkpile! Pick yourself up, get back into the city and save her. Beautiful art, much pointy-clicky puzzle solving.||Official site|

The year is 2794 and you are a security officer aboard the UESC Marathon, a large, multi-generational colony spacecraft (converted from one of Mars's moons).

Now, it will awaken in a few days, and when it does, it will destroy the world entirely. The only solution is to get it back to bed, by means of a nuclear bomb planted on the lowest levels of a mysterious pyramid of non-human origin.
The predecessor to the Marathon series, very unique, and one of the hardest games ever.
|Portal||Puzzle||2007||You're a "volunteer" at an experimental research facility managed by an AI who is lacking in ethics and doubtful sanity. Your job is to test a device that can connect two surfaces together. You are promised cake if you complete the tests successfully (spoiler: the cake is horrible-screaming-death flavoured).||Steam|
|Portal 2||Puzzle||2011||A sub-AI module dug you out of cryostasis to help get out of the testing facility. The AI from the last game is deactivated, so it should be easy so long as you don't reactivate her. Just don't press the 'on' button... the red shiny 'on' button... the jolly candy-like OH FOR CHRIST'S SAKE!!! More puzzles, more gimmicks, plenty of background fluff and top-notch voice acting. Also comes with 2-player co-op first-person puzzle mode (2PCOFPPM?).||Steam|
|Prey||FPS||2006||A deadbeat Cherokee ex-soldier is abducted to a massive spaceship that feeds from people, and he has to use his injun spirit magic to beat the aliens and save the world. Silly as it may sound, this is a very solid game (if somewhat linear) with great graphics, a haunting soundtrack, excellent writing, and voice cameos by tinfoil hat radio celebrity Art Bell as himself. Also on Windows and Xbox 360.||Aspyr|
|Quake 4||FPS||2005||Continuing the plot of Quake 2 (1 and 3 don't really have one), you're a space marine fighting the Stroggs, a conquering cyborg alien race. It got a bit of an underwhelming reception, but it's actually very fun. It's more linear and "cinematic" than its predecessor, but still feels old-school enough (no auto-healing or weapon limit bullshit, thank you based god).||Aspyr|
|Rochard||Platformer / puzzle||2011||When an asteroid mining crew finds evidence of intelligent life out there, they're attacked by space bandits, and soon find themselves as targets of a nasty conspiracy. Excellent graphics and sound, some nice run-n-gun action, and a ton of crazy physics-manipulating puzzles.||Official site |

|Team Fortress 2||FPS||2007||An official sequel to the Quake modification, Team Fortress. The game revolves around nine unique classes and hats. A lot of hats. It's updated regularly and has been receiving consistent content since it's release.||Freemium:|
|The Witcher 2||RPG||2012||GOG|
|Torchlight||RPG||2010||A modern roguelike from the designers of Diablo and the team behind Mythos - so if you liked those, get it.||Steam|
|World of Goo||Puzzle||2008||Is there any platform that World of Goo doesn't run on? Help sticky blobs of, well, goo to cooperate so they can get from point A to point B. Simple idea, it's the art and decorations that make it memorable.||Official site|
