Last month Deus Ex: The Fall made the jump over to the PC on Steam, and now it's available for the Mac. As always, if you already bought the game at release, you can just load it up on a Mac with the same account and you're good to go.
It was neat on a portable device, but it seems as if the game hasn't translated well to the PC, so buyer beware. It would be perfect for a high percentage drop Steam sale, though, if you're a hardcore franchise fan.
