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)
Expand Finder Columns Quickly
Column view in the Finder is great for navigating through your disk's hierarchy, but the columns often aren't wide enough to show the full names of all the files. To expand a column to a width that will show all file names in their entirety, double-click the handle that you would normally drag to expand or shrink the column. To expand all the visible columns to that width, Option-double-click the handle.
