I'm going to reply here with (almost) the same thing I told you in PM.
The Development team is currently up over its ears in finishing Aion for launch, and I'm afraid that a Mac version may not be one of the initial priorities. If not, unless there's any technical limition, there is nothing preventing it for consideration in the future - if the developers consider it possible - depending on the needs and feedback from the community. I'm not an (overly) experienced programmer myself, but I'm sure that 'Cider' would be taken into consideration, as any other viable options, should we get an opportunity to pursue it.
