I did bootcamp (extremely simple process; just need a valid windows key and the process will hold your hand through the rest of the setup. Give it at least 60GB of space) and installed FFXIV there. My 2015 Macbook Pro 15" is able to run FFXIV on Laptop medium settings at a consistent 40fps or higher. I could go higher but I don't want to really dip below 30-40fps.
