Apple's search tool, Spotlight, is even smarter in Mac OS X El Capitan. You can now use Spotlight to check stock prices, weather conditions and forecasts, sports scores, schedules and standings, and even info on an athlete information.
You can also search with Spotlight to find a file using natural language. Simply type "email from Steve Sande in September," "Word docs I worked on yesterday," "photos I took last month," etc., and Spotlight helps track down those items.
You can use Spotlight to find out the local weather — or the weather conditions in another city. Type in "Weather in [location]." For instance, if I want to find the weather in my location, I'd type in Weather in Nashville, TN."
You can find online videos. Type in "[name of] video" in Spotlight.
You can find information on your favorite sports teams with searches for "(team name) score," "(team name) schedule," etc. For instance, if I want to find out the score of the latest game by my favorite football team I'd type "Titans score."
What's more, you can resize the Spotlight window to display more results or move it anywhere on your desktop.
By the way, command-spacebar is still the keyboard shortcut to launch Spotlight Search.
OS X El Capitan is available as a free update from the Mac App Store. The operating system upgrade supports all Macs introduced in 2009 and later, and some models introduced in 2007 and 2008.
