Apple's New Mac Software Includes Little Changes That Make A Big Difference

Apple's new operating system for Macs, called OS X Yosemite, is available to download from the Mac App Store starting Thursday.

Yosemite represents a bold visual redesign, but one that still feels rooted in the familiar simplicity that Mac users have grown to love.

The result is a cleaner, more vibrant operating system that takes a few design cues from Apple's mobile operating system, iOS.
