They say that "bigger is better," and Apple is looking to wow the crowd at the Worldwide Developers Conference this year when it rolls out the newest features for OS X 10.10.
Apple's newest look for the Mac will be similar to the updates rolled out in iOS 7.
"The new look will have similar toggle designs to iOS 7, sharper window corners, more defined icons across the system, and more white space than the current version. However, OS X characteristics like the Finder, multi-window multitasking, and Mission Control will not disappear in favor of a more iOS-like experience. Apple is keeping iOS as iOS and OS X as OS X. The convergence will solely surround feature parity that makes sense and aesthetics. Apple is aiming to release 10.10 by fall and is planning a slew of hardware updates to promote the new software."
Apple has also been grabbing up trademark rights for Yosemite, Diablo, and Mammoth National Parks. It looks like Apple is going to go big, or go home with the largest redesign of their desktop software yet.
