Computer: Warcraft III requires a 400 MHz G3 processor or better.As many posters have previously noted in the IMG Forums, suggested system requirements aren't necessarily the final word, and the experience of different users will vary. However, the requirements suggested above should at least give Mac gamers an idea of what kind of machine will be needed to run Warcraft III when it sees release.
Operating System: Warcraft III: Reign of Chaos requires Mac OS 9.0 or higher, or Mac OS X 10.1.3 or higher.
Memory: Warcraft III requires 128 MB of RAM. Virtual Memory must be enabled and set to Apple's recommended setting on computers running pre-Mac OS X versions of the Mac OS.
Controls: A keyboard and mouse are required. Joysticks, game pads, graphics tablets, and input devices other than a mouse and keyboard are not supported.
Drives: A hard drive with 700 MB of free space, and a CD-ROM drive are required for installation and play.
Video: A video card consisting of an ATI Technologies or nVidia chipset with at least 16 MB of memory is required.
Sound: Warcraft III: Reign of Chaos will work with the "built in sound" features of the Mac OS.
Multiplayer Connectivity: Access to Blizzard Entertainment's online gaming service, Battle.net, requires a low-latency, active Internet connection, rated at 28.8 Kbps or faster. Multiplayer games played over a LAN require an active connection to a TCP/IP network.
