Very disappointed due to lack of advance warning

I was looking very much forward to this game and bought it without hesitation.
Since even a very careful look at the game description provided no hint of the hardware requirements, this felt right - until the purchase was made and the download quit, saying that my iMac’s graphics card is not supported (which, by the way, was not a problem with Anomaly part 1). Thus, I have spent money without getting the content (it will not even let me download the game).

Why was there no advance warning about the hardware requirements on the game page…?!? I also did not find information about this on the “Anomaly 2 Support” page. A real shame, all the money wasted… for nothing. And I was so looking forward to playing this game, and would most probably have given it a rather favourable rating!
As “Johnniehare”, I am running OS X Mavericks.
