October 27, 2009, 8:31 PM — On Tuesday, Apple released software updates for Leopard and Snow Leopard to support the new Magic Mouse ( Macworld rated 3.5 out of 5 mice ).
The 64MB Wireless Mouse Software Update 1.0 for Snow Leopard requires OS X 10.6.1, while the 36MB Wireless Mouse Software Update 1.0 for Leopard requires OS X 10.5.8. Apple's release notes simply state, "Install this software to take advantage of your Magic Mouse special features."
The Magic Mouse features Apple's Multi-Touch technology, and ships with the latest iMac models, released on October 20. Apple now sells it separately as well for $69.
The Magic Mouse replaced the Mighty Mouse, the name of which Apple was forced to change recently for trademark reasons.
