When you refine every detail, the entire experience is enhanced.

Thoughtfully redesigning OS X meant going deep into every aspect of the interface and focusing on details large and small. There are obvious changes to big things, like translucency in windows and streamlined toolbars. And there are more subtle changes to a lot of small things, like the buttons, icons, and font you see throughout the system. The more you use your Mac, the more you’ll notice, and the more you’ll love it.

Translucency adds more dimension to your desktop.

By adding translucency to certain interface elements in OS X Yosemite, apple have put a greater emphasis on your content. Translucent toolbars let you know there’s more to see than what’s visible in the window as you scroll. And a translucent sidebar lets you see what’s hidden behind the active window. So the interface takes on the look of your desktop image and your content — making your Mac experience different from anyone else’s.

Streamlined toolbars put more features into less space.

In OS X Yosemite, apple have streamlined the toolbars in some of your favorite apps without losing their capabilities. For instance, in Safari you can now access your favorite sites by clicking in the smart search field. With just one click of the Tab view button, you can see the Safari tabs that are open on all your devices. They have streamlined Maps and Calendar, too. Which means the apps give you more room for what you care about.

Controls that are smarter in both form and function.

A lot of what you do on your Mac requires clicking things like buttons, checkboxes, and pop-up menus. In OS X Yosemite, they have redesigned these controls to make the Mac experience feel cleaner and more refined throughout the system. And apple have made them smarter as well. Take the red, yellow, and green “stoplights” in the corner of every app window. Not only have they streamlined their look, but they’ve also updated their functions. Close, minimize, and maximize are now close, minimize, and full screen, eliminating the extra full-screen control and consolidating the window controls in one place. Streamlining these and other elements of the interface means you can navigate the desktop more efficiently. And you can get the most from your beautiful Mac display.

A cleaner, more iconic Dock.

There are several ways to launch an app. But most likely you look to the Dock. With OS X Yosemite, we’ve simplified the appearance of the Dock and its icons to provide a more consistent look and feel. This new approach to the icons gives the entire app family a more harmonious look while making each one instantly recognizable.

More elegant, from A to Z.

For some, the choice of a font may not be a big deal. But to us, it’s an integral part of the interface. In OS X Yosemite, fonts have been refined systemwide to be more legible and consistent across the Mac experience. You’ll notice a fresh, new typeface in app windows, menu bars, and throughout the system. And it looks absolutely incredible on the Retina display.

Enjoy the view in all your favorite apps.

OS X Yosemite brings a new look to apps like Safari, Mail, Messages, and more. But it’s not just about how much better they look. It’s also about how much better they work.

The real beauty of OS X Yosemite lies in what you can do with it.

Apple’s goal in redesigning OS X wasn’t just to make the interface more beautiful. It was to make it more useful, too. To do that, apple found ways to introduce powerful, intuitive features that are accessible at all times. So you can access important information without being distracted from what you’re doing.

Notification Center. There’s so much more to see at a glance.

The new Today feature in Notification Center tells you everything you need to know now. It gives you a concise summary of the day’s upcoming events, reminders, and birthdays. It even summarizes tomorrow’s events. In addition, you’ll get quick access to important information with widgets like Calendar, Weather, Stocks, World Clock, Calculator, and Reminders. And you can customize what you see by adding more widgets from the Mac App Store. You can access Notification Center with just a swipe. It’s always available, even when you’re working in full screen.

Spotlight. Now brighter than ever.

The fastest way to find things on your Mac keeps getting better. The redesigned Spotlight appears front and center when you open it. It’s great for looking up information from sources like Wikipedia, Bing, news, Maps, movies, and more. And it gives you richer, more interactive previews of your results. So you can read a document, send an email, or make a phone call by clicking a result.
