Follow up to my previous response: the FAQ on SteelSeries' website specifically says that it's not compatible with the Mac. Given the way Apple has positioned the MFi controller API, it really should work on Mavericks, so I'd be willing to bet on it working down the line.
Though it is possible that there will be a separate Mac version, that just simply doesn't make sense, too fragmented. Apple doesn't make iOS-only bluetooth keyboards or AirPlay devices. While it's obvious Lightning connector controllers won't work, it makes sense for the bluetooth ones to work.
