Official support for Linux and Mac platforms, using Transgaming Technologies Cedega and Cider (forks of Wine) for Linux and Mac compatibility, was introduced with the Revelations 2.3 patch released on November 6, 2007. At Fanfest 2008 Transgaming announced and demonstrated that the Premium graphics client is now running on Mac OS X 10.5 Leopard. In February 2009 CCP announced that they planned to discontinue the official Linux client with the next major patch, and advised on using third-party programs to run the Windows version of the client under Linux (namely Wine). The discontinuation of the official Linux client was primarily because the game ran better using the Windows client via Wine than it did with the official one, as a result many Linux users were already using Wine instead.
