Take look of os yosemite

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.
