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)

Adjust Multiple Column Sizes Simultaneously
Within the Finder, Column View enables you to see folder hierarchies, with each subsequent level getting its own column. Dragging on the double lines at the base of a column divider changes the preceding column's width. But Option-drag on any divider, and all the columns in the window change to the same width.
