I went to Quake Live and installed the plug in. But when it came to playing the game, I couldn't. I signed in and everything and all I saw was a black square (where the game was supposed to be). Did I install the wrong plug in? Does Quake Live work on the Mac OS? Aside from being a bit disappointed in not being able to play the game, I really liked the Macbook pro overall. The click button built in the track thingy was really cool. I also prefer how to install/uninstall and search for programs on a Mac over a PC. So, I went home and bought the high end 13" one .
