FFXIV +Macbook

[Asunna]

I have no idea if I posted this in the right category or not.. But I need your help!
I want to run FFXIV on my macbook pro 15" (I know it's not the best and it's not a gaming computer, but I would like to play the game when I'm away from home and have nothing to do.. :P)

I would probably need to download stuff + update my mac since I only got it for school and haven't change anything yet. Can you guys tell me what I would need to do?

My mac:
Processor 2.3GHz intel core i7
Memory 8GB 1600Mhz DDr3
Graphics: Intel HD Graphics 4000
Storage: 500GB + I do have an external hard drive (also 500GB)

****I don't give a crap about graphics!!! Like I mention before, I would only play the game when I'm away from home. Usually I play on PS3 soon to be PS4. All I want is to be able to run the game with little or no lags (if possible).

Thank you for your help!!
