Apple Mac OS X El Capitan is bringing a lot more for your read below:
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.
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.
After the introduction of Metal API for iOS 8 last year. It is now added to Mac OS X El Capitan.
Who says you can’t focus on two things at once?
Running lots of apps at the same time is one of the great things about using a Mac. Focusing on just one app in full-screen view is another. With Split View, you get the best of both. It automatically fills your screen with the two apps you choose. So you can make dinner plans with a friend in Messages while finding the restaurant in Maps. Or work on a document in Pages while doing your research in Safari. All without the distraction of your other open apps, and without having to manually resize and drag windows around. And your desktop is always just a swipe away, so it’s easy to get back to everything else you were doing.
You’ve never been so good at space management.
A streamlined Mission Control makes it easier to see and organize everything you have open on your Mac. With a single swipe, all the windows on your desktop arrange themselves in a single layer, with nothing stacked or hidden. Mission Control places your windows in the same relative location, so you can spot the one you’re looking for more quickly. And when you have lots of windows competing for real estate, it’s now even simpler to make more room for them. Just drag any window to the top of your screen, and drop it into a new desktop space. It’s never been this easy to spread out your work.
Call out your cursor.
Lost your cursor on your crowded desktop? Just shake your finger back and forth on the track pad or give your mouse a shake, and the cursor gets bigger so it’s easy to spot.
Ask in your own words.
Searching for files has never been easier now that Spotlight understands natural language.1For 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.
Now arriving. Public transit info.
If you get around by train or bus, you can now get around more easily in select cities around the world thanks to Maps. You’ll find everything you need to go from point A to point B, including built-in public transportation maps, directions, and schedules.
Mac be nimble.
In OS X El Capitan we’ve made all kinds of things run faster — like accessing email and launching or switching between apps. It’s these little things that make your Mac feel faster and more responsive. And we’ve brought Metal to Mac, so you experience more fluid performance in games, high-performance apps, and key system-level graphics operations.
Now things you do every day — like launching and switching apps, opening PDFs, and accessing email — are faster and snappier. OS X El Capitan makes your Mac feel more fluid and responsive.
