My story in short: Late 2007 Macbook Pro with 2GB RAM.
Beta 1: Ran excellent at Medium Settings plus 1920x1080 Res. Had awesome battles and got up to the gold league.
Beta 2: Got cussed out by fellow players to lower my settings down to the point of where EVERYTHING was on the lowest settings and still am getting "You should lower your graphics settings" box. I was on the outer edge of the Bronze league.
Release: All low settings, game lags but it's playable but isn't necessarily enjoyable. The game's supposed to get better throughout development, not worse right? Blizzard, please get your act together on the Mac issue. It shouldn't be like this.
Mac Known Issues
No user interface/menus
When you log into the game you will see the spaceship, but there is no place to enter your Battle.net information.Rebooting your system will resolve this issue.
You don't actually need to reset the game however, you can (command+m) to exit full screen and send it to the corner for a time out and then when you cmd+m again to full screen it resets the problem and the countdown to mega lag resets.
Threats of violence. We take these seriously and will alert the proper authorities.
