I remember reading that back when it launched Blizz got about 1 million using the Mac Client. No idea what that number might be these days though given the fluctuations in player base vs the rise in popularity for Macs over recent years. I never had any problems with WoW even as they upped the graphics reqs over successive expansions. I played ESO on my Mac for a good few months as well and that was seamless.
