With Apple's recent announcement they're moving their entire platform to their custom ARM chips, this should be getting a bit more interesting.

I imagine SE will not be making any major changes aside from waiting for WINE to ensure it's safely compatible with Rosetta 2 to translate x86 code while also running all of the DX -> OGL/Vulkan things too. I would not be surprised if we see instances of "FFXIV cannot be run on the newest Macbook" messages come the official release.
