World of Warcraft®

*Updated for patch 4.3.4*

A 64-bit client is once again available for use with Patch 4.3.4. Before being able to launch WoW in 64-bit mode you will need to download the 64-bit client for PC/Mac (using one of the links below), and unzip it into your World of Warcraft directory. Once you extract the files you can start the 64-bit client by opening the Launcher as normal (Run as Administrator if applicable). To switch back to the 32-bit client, go into Options -> Game Preferences, and check the Launch 32-bit client setting. The game will display which version you are using at the bottom left hand corner of the login screen. ex: Version 4.3.4 (15595) (Release x64)

Build 4.3.4.15595 - Mac
