Apple has released two updates that enable users running either Leopard or Snow Leopard to take advantage of the multi-touch capabilities in the new Magic Mouse (see "Apple Releases Magic Mouse, New Remote, Souped-Up Base Stations," 20 October 2009). Apple notes that users running Leopard must have version 10.5.8 installed, and that Momentum scrolling is not available. Users running Snow Leopard must have version 10.6.1 installed. Both updates are available via Software Update or the Apple Support Downloads page. (Free, 36.22/63.92 MB)
Show Recent Items in Snow Leopard
The Recent Items submenu in the Apple menu is handy, but what if you want to work with a file in there in the Finder, rather than open it? Just press Command when that menu is showing, and all the Applications and Documents change to "Show ... in Finder." This feature is new as of Mac OS X 10.6.3 Snow Leopard.
