Hi! like a number of people, I've been waiting for a mac client for quite some time. Bootcamp does get a little long in the tooth sometimes, especially since FFXIV is a game I'd like to keep logged in in the background while doing other things. The lack of communication about the mac port until its final release has been absolutely appalling, considering Guild Wars 2 has had the same form of port, and for the most part, was optimised quite well for what it was. It even had multitouch support for the trackpad.
It would seem that Transgaming was looking at making a quick buck with FFXIV which is troublesome considering how difficult it was for the wine community to make a custom wrapper for the game. It had to do with a lot of windows dependencies outside DirectX.
The other problem is that Transgaming just sold its porting technology to Nvidia, which doesn't bode well for future support of FFXIV or any Cider wrapped games.
It is also a shame considering how well the PS4 port runs, as OSX and the PS4 platform share a lot of similarities, from OpenBSD to OpenGL. I would assume that porting from the PS4 to OSX would have been a smoother transition. It would have been more work initially but far more sustainable.
Going forward, it seems like the only possibility for a Mac Client at this point is handing over the project to yet another third party studio for a complete rewrite. The two major names that come to mind are Aspyr and Feral as their ported games do run quite well. I also believe that a focus on the newly introduced Metal API on OSX 10.11 would probably yield the best performance, especially since the claimed minimum requirements for the Mac client also happen to be the base hardware requirements for Metal in OSX 10.11. If it had been completely rewritten, then the asking price of 60$ would have been arguably warranted, even though most other publishers treat Windows and Mac licenses as one and the same.
I believe the initial volume of sales for the OSX port including customers asking for a refund as well as potential clients like myself that held off until we've seen some feedback about performance should indicate to Square Enix how viable a Mac port would be.
In the meantime however, the game is best played on PC/Bootcamp or PS3/PS4. The Mac promise has been broken for now.
I'll be back to levelling my Paladin after a long break to try to finish the story quests before getting Heavensward.
