Unfortunately its for Windows only :D.

Now that we know the answer to the 64-bit question (http://blogs.adobe.com/jnack/2008/04/photoshop_lr_64.html), am holding off any plans of getting a Mac Pro for Photoshop until CS5 hits the market. But who knows, might still get one for Lightroom since it's already on the right track already.

Actually the big question is this: Now why didn't Adobe develop for Cocoa in the first place? And while they are at it, put in CoreImage as well.
