You're right, he doesn't have to apologize to me, but he does need to understand that the way this post is worded it can easily be misconstrued.
Also I fail to see how the post is THAT useful, since he's basically asking if anyone plays the game on a PC made by Apple, since they are, well PCS just like any other. They tend to charge more for the same specs, but that's not really my point. One person showed they played via something similar to(or even a branch or fork of) WINE. The client is a Windows Client, there is not OSX client. There's no need whatsoever to know if someone plays on a Mac or non MAC PC, since they are ALL PCs. If someone can get it to play decently on OSX, that's a different story. But the OP didn't say anything about OSX, only a MAC, which isn't special at all since it's a glorified PC.
