Final Fantasy 14 is widely regarded as an unlikely comeback story. However, the Mac version of the game has continued to suffer from issues. For this reason, Naoki Yoshida has shared a lengthy apology and explanation, and is also offering refunds.
First, the explanation. Yoshida stated that the call to make a Mac version ultimately came from the fans themselves, who wanted a proper working version of the game on their platform. The Final Fantasy 14 opted to do this port by using middleware that turns DirectX to OpenGL.
This choice is relevant because it meant the Mac version would never have performance parity with the Windows version. As a result, you need to have higher range Macs than Windows PCs to run Final Fantasy 14.
Square Enix admits and apologizes for miscommunication regarding Mac requirements, that led some owners to believe they could run the game on Mac models that were actually not capable of running the game.
Ultimately, it was for this reason that they are offering refunds. Square Enix has also opted to halt sales of Final Fantasy 14 on the platform.
If you own the Mac version of Final Fantasy 14, you can request a refund here, and if necessary, file further complaint forms in case there are issues with refunds here. Square Enix is also already talking to retailers who sold the Mac version, so if you got it that way, you may be notified by your retailer of choice about this soon.
