I have played World of Warcraft on my PC for years and now finally have an iMac and want to migrate on to playing the game on there. What is the easiest way to obtain the game? I am assuming my PC licence will not work anymore or is it linked to my account? Are there any trials to download and then pay for the game or do I need to buy all the discs including expansions again? Not trying to do anything illegal here by the way, I would like to know the simplest way to move my game playing to my iMac.
