Redesigned interface. Completely new. Completely Mac.

With OS X Yosemite, we set out to elevate the experience of using a Mac. To do that, we looked at the entire system and refined it app by app. Feature by feature. Pixel by pixel. And we built great new capabilities into the interface that put need-to-know information at your fingertips. The result is that your Mac has a fresh new look, with all the power and simplicity you know and love.

Mac and iOS are connected like never before.

Use a Mac or an iOS device, and you can do incredible things. Use them together, and you can do so much more. Because now OS X and iOS 8 enable brilliant new features that feel magical and yet make perfect sense. Make and receive phone calls without picking up your iPhone. Start an email, edit a document, or surf the web on one device and pick up where you left off on another. Even activate your iPhone hotspot without ever taking your iPhone from your pocket or bag.

Do everyday things in extraordinary ways.

One of the best things about a Mac is that it comes loaded with state-of-the-art, beautifully designed apps you'll love to use every day. In OS X Yosemite, those apps give you new ways to do some of the things you do most. The apps you use to surf the web, read your mail, send messages, and organize your files and content have a simpler, more elegant look, and we've enhanced them with powerful new features.
