Is there left 4 dead 2 for mac

Left 4 Dead 2 is not made specifically for mac, but if you use crossover games or cider on an Intel mac you can play PC games natively on mac. Alternatively, you can install windows through boot camp or a vurtial machine, but windows tends to be buggy and your computer may randomly shut down during game play, so stick with cider.

From April 2010 Left 4 Dead 2 will be available for the Mac via Steam. (See links below)
