League of Legends has finally released that Mac open beta that we heard was coming just a little while ago. Back in 2010, Riot Games had a ported Mac version all ready to go, but eventually determined that it just wasn't good enough, and not compatible with, the way they wanted to run their game. That led to a shutdown on development, but the company secretly restarted work on a native client, and it's now out and ready for download for everyone.
