Spotlight searching expands its repertoire
Spotlight started as a relatively simple system search tool. Today, in Yosemite, it's a full-fledged Internet crawler that can not only rifle through your OS, but also the web, Wikipedia, news headlines, maps, Bing, the App Store, iTunes, and even movie show times. We discuss all the new Spotlight features here.
Mail, Messages and Calendars
OK, they don't pack the same levels of glitz and glamour as the tweaks listed above, but changes to Mail, Messages, and Calendar will certainly influence your Yosemite experience. You can read about new features like Mail Drop, Markup, and Soundbites here.
