I play FFXIV on my MacBook Pro all the time. Apple provides BootCamp not just an option to use Windows, but to use windows with proper drivers that allows Macs to run Windows better than most non-Apple machines with simular hardware specs.

While I would not mind a native OS X client, the fact is that this would require more time for SE to code the game in OpenGL (currently coded in DirectX and ps3 code) which willbfurther detract resources from them making FFXIV a better game.

If we can survive FFXIV not bombing a second time I could see SE putting toward the resources to make a Mac client, granted we get enough subs in the next year or 2. If there are only 500,000 or less subs by the end of 2013 (I have my doubts about even reaching this number), I'd toss the thought of them putting down the dev cost for a new client. Keep in mind, wow had MILLIONS of players already when they added the Mac Client.

At the end of the day you can play FFXIV on your mac just fine, sadly you just choose not to.
