Inside Mac Games:

Riot Games has announced the cancellation of League of Legends’ Mac beta client, which the company was developing in partnership with TransGaming. Riot cited the reason for cancellation as an inability to maintain consistent parity between Mac and Windows PC versions with the game’s rapid update cycle. Announced last year, the DOTA clone is a session based multiplayer online game which challenges rival teams to compete for victory.

Disappointing news for anyone who was looking forward to this 3D fantasy MMO.
