A guildmate received the update via launcher. Under El Capitan on a Mid 2011 27" iMac with an AMD 6970M video card, it doesn't display properly. The actual game window is shifted up so that the top third of the game is outside the top border of the monitor. I can't speak for anyone else, but my guildmate's experience thus far has been frustrating. It took three times just to get the issue reported (a phone call that started with "we don't support Mac" and ended with "post on the in-game bug forum"), a bug report post that got moved to incomplete status and a bug report post that was finally accepted sometime in the last 24 hours. If it wasn't for my other guildmates, they probably would have given up and quit by this point.
