I bought this product based on the previous review which said it was compatible with 10.6. It is actually compatible with Intel Macs from 10.6 Snow Leopard (not earlier systems) but is "inconsistent" (understand it's going to row) with video cards of 2006 Macs, namely X1 ATI --- , Nvidia and 7 --- INTEL GMA and the Nvidia 9400M.
It is also stated that the Macs with Intel HD3000 and Nvidia 320M video card must have at least 4GB of RAM, and the other at least 2GB.
Nevertheless, I began to play on my old mac with a lousy ATI X1600 (by cons I shielded RAM as much as I could) and it's still playable. The very beginning, which is only there to start getting used to the movement and others, was endless because it was rowing boat as a hole in the mud, but once you're in the game itself, it n 'there is that small lags and even fights do not suffer too much.
Honestly I'm not a great player, the proof is that I play on an old Mac (!), But I bought the Logitech F310 controller that is compatible with Batman Arkham Asylum and offers great comfort of play. making this Batman in easy mode as a good n00b, there just enough challenge to make it exciting, without getting screwed at the first turn, so all is a great initiation for cheap manageability console games .
So now, be warned: this game is great, but is beginning to be too heavy for old bikes.
