I am having the exact same issue. I just bought the mac version and I cannot get it to launch. I would try to open it and it would say Verifying "FINALFANTASYXIV" then nothing would happen. I would try to open it again and it says it cannot open because it's not responding. Then when I try to uninstall it I have to restart my entire computer because it says it's already open and I have no other way of closing it as it does not show in finder or my dock.

I am fairly new with mac as I just bought my mackbook pro last September. Am I doing something wrong? I followed the instructions in the SE store and it seems like there's nothing else I can do besides wait on my tickets to be answered.
