Runs on: Mac OS X 10.4.11 or later World of Warcraft: Wrath of the Lich King for Mac OS v.1.0 The Lich King Arthas has set in motion events that could lead to the extinction of all life on Azeroth. Hota is a mod that's make many changes and fixes, mainly adds new castle. It have an option 'online lobby' when you click multiplayer. Works well and you don't need to use any other programs or port forwarding. I downloaded a game then hd mod and in hd mod launcher there is an option to download hota. Or you can probably just download hota.
