The forthcoming Mac OS X 10.6.2 update will be required for Magic Mouse compatibility in Snow Leopard, an Apple support document reveals. The mouse's user guide -- quietly published on Apple's website yesterday -- mentions that a "full range of features" will not work without v10.6.2. Leopard users must have a combination Mac OS X 10.5.8 and the unreleased Wireless Mouse Software Update 1.0.
