Mac Game Downloads Demos

Can anyone send me a link to the Mac version of Left 4 Dead demo?

I have a Mac Book and I was wondering if there was a link anywhere to download video game Left 4 Dead Demo

No, you need to install something like Bootcamp, and then install Microsoft Windows XP .. and then XP boot up, install the necessary drivers and then download a torrent demo of Left 4 Dead from the demo via Steam will not work, then Install Left 4 Dead .. and play by yourself, unless you can get the demo to work online via Hamachi.
