Mac Client

[Fyce]

Can someone, a staff confirmed that the Mac client is going to be available for free for current FFXIV players?

There is no ARR Mac Client currently announced to be available on its own.
The only Mac version that exist, and is currently in pre-order, is the complete edition ARR+Heavensward.

Nobody currently knows if the Mac version will ever be available for download, and if that's the case, we don't know if it will be free or not if you already have a PC registered licence.
