Apple previewed OS X Yosemite at WWDC last week and released the first beta for developers and beta testers. The OS X update sports an all new design, in line with the changes iOS 7 underwent. Here’s a detailed look at these changes.

New login screen

The login screen has been revamped with a cleaner design and a new animation:

New app icons

iOS 7’s app icons caused an uproar within the design community for some of the choices, but the reaction to OS X Yosemite icons has been more positive. The icons feature a flatter, sharper and cleaner look, with some notable changes like the Finder’s smile becoming broader and more curvy, and the Trash icon becoming white:

New System Font

In OS X Mavericks and earlier, the system font was Lucida Grande, but Apple’s changed it to Helvetica Neue in Yosemite.

Revamped Menu Bar

The Menu Bar has also undergone some changes, including the new Helvetica Neue font, new icons and some other subtle tweaks:

Translucency

Just like iOS 7, Apple’s made heavy use of translucency and blur to convey depth between different layers of the interface, and to maximise the screen real estate given to content.

New Window buttons

The close, minimise and maximise buttons present on all OS X app windows now features a new, flatter look:

Safari changes

Safari, by default, hides the bookmark bar, and shows you a toolbar with a very minimal, translucent look. The URL bar now shows you just the domain name of the website rather than the full address:
