WORKS NOW!
So I wanted to try out Starcraft 2 again so I go to the Blizzard website, download the client, unzip the ZIP and then press the installer. Nothing happens! I press it and the icon pops up a bit like when you start any program, nothing happens in the dock, no windows opens. I don't know what to do. So I ask you mmo-champs if there is any solution to this.
IF YOU HAVE THIS PROBLEM ASWELL, DON'T OPEN THE ZIP WITH ANYTHING ELSE THEN THE DEFAULT ONE THAT YOU GET WITH THE MAC!
