Experience
OS X El Capitan gives you even simpler, smarter ways to do the things you do most with your Mac. Like working in multiple apps at the same time. Searching for information. Keeping tabs on your favorite websites. Checking email. Taking notes. And much more.

Performance
Improvements under the hood make your Mac snappier and more efficient in all kinds of everyday tasks — from opening PDFs to accessing your email. And with Metal for Mac, you get faster and more fluid graphics performance in games, high-performance apps, and many other places.

Search results from more sources.
Spotlight now searches even more places to give you more useful results. Check up on the latest stock prices, weather conditions and forecasts for your current location or cities around the world, and sports scores, schedules, standings, and athlete information. You can even search for web videos.

Ask in your own words.
Searching for files has never been easier now that Spotlight understands natural language.1 For example, type “email from Harrison in April” and Spotlight shows you email messages that match. You can also use more complex searches, like “presentation I worked on yesterday that contains budget,” and you’ll get just what you’re looking for. You can search with your own words in Mail and Finder, too.

Look what just landed in your inbox.
Improved full-screen support and swipe gestures in Mail let you make quick work of your correspondence. OS X even helps you manage your calendar and keep your contacts up to date, right from your inbox.

Work more easily in full screen.
The enhanced full-screen view in Mail lets you juggle all your email conversations at the same time. The email message you’re composing now slides to the bottom of the screen, so you can access your inbox — perfect for copying text or attachments between messages. And if you’re managing multiple email threads, you can switch between them with easy-to-use tabs.

Add suggested events.
When you receive an email containing details for an event like a flight or a dinner reservation, or even a suggestion like “Let’s have drinks at 5,” you can add it to Calendar with just a click.2

Add suggested contacts.
When you exchange email with people who are not in your contacts, Mail lets you add them with a single click.3 It even lets you know when the email address for one of your contacts has changed.
