Apple Preview it's new version on OS X called El Capitan.
“OS X delivers unparalleled integration between Mac hardware, iOS devices, apps and online services, and has helped Mac sales outpace the PC industry every year for the last decade,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “Customers loved last year’s landmark OS X Yosemite release and made it the fastest-adopted PC operating system ever. With El Capitan, we’re further refining the Mac experience with enhancements to window management, Spotlight and built-in apps, and improving performance so everyday activities — from launching apps to accessing email — are faster and more responsive.”
Refinements to the Mac Experience
OS X El Capitan refinements begin with the new system font, San Francisco, a modern and easy-to-read typeface that looks stunning on a Retina® display. Mission Control®, the quickest way to view all open windows, has a cleaner design so you can find the window you need even faster. When your desktop gets crowded, simply drag a window to the top of your screen to access the new Spaces Bar in Mission Control and create a new Space, OS X’s intuitive way to group applications. And, the new Split View feature automatically positions two app windows side-by-side in full screen so you can work with both apps without distraction.
Built-in apps are even more streamlined in El Capitan. Safari® now features Pinned Sites to keep your favorite websites open and active in your tab bar and a new mute button to quickly silence browser audio from any tab. Mail introduces Smart Suggestions, which recognizes names or events in a Mail message and prompts you to add them to your contacts or calendar with a single click. You can also now swipe to delete messages, just like in iOS, and juggle multiple emails while Mail is in full screen. In Photos, you can add locations to a single image or an entire Moment, and sort albums by date or title. Additionally, you’ll be able to download third-party editing extensions from the Mac App Store℠ and access them directly within the Photos app.
With the all-new Notes app in El Capitan you can drag and drop photos, PDFs, videos and other files into notes, and add content directly from other apps, such as Safari or Maps, using the Share menu. Easy-to-create checklists help you keep track of important to-do items, and the new Attachments Browser organizes your attachments in one simple view, making it easy to find what you’re looking for. With iCloud®, your notes stay in sync across all your enabled devices.
Spotlight gets even smarter in El Capitan, generating results for even more topics, including weather, stocks, sports, transit and web video. You can now resize the Spotlight window to display more results or move it anywhere on your desktop, and use natural language to find documents and files on your Mac based on when they were created or who you sent them to.
Improvements to System Performance
OS X El Capitan improves system performance across your Mac, making many of the things you do everyday faster and more responsive. Metal, Apple’s groundbreaking graphics technology, accelerates Core Animation and Core Graphics to boost system-level rendering by up to 50 percent,* and efficiency by up to 40 percent,** resulting in faster graphics performance for everyday apps. Metal also takes full advantage of your CPU and GPU, delivering up to 10 times faster draw call performance for a richer, more fluid experience in games and pro apps.*
El Capitan also features enhanced international language support, including a new Chinese system font for both Traditional and Simplified, with 50,000 beautifully designed characters for crisp on-screen readability. Chinese keyboard input methods now offer regularly updated vocabulary lists and a smarter candidate window. El Capitan makes entering Japanese text faster by automatically transforming Hiragana into written Japanese and reducing the need to individually select and confirm word conversions. You can now also select the perfect font for your documents using four new Japanese typefaces.
Split View automatically positions two apps side by side, using every pixel of your Mac display.
New gestures make it easier than ever to do quick actions like deleting a message in Mail.
El Capitan is available to developers today.
A public beta will be available in July with a public release in October 2015
