Apple's latest desktop operating system, OS X Yosemite, is now available to download from the Mac App Store. It's a free update, and it delivers a whole host changes, most notably a revamped visual style that's a lot more colorful than the OS X you're used to. In fact, the Yosemite makes your Mac's operating system look a lot more like iOS than traditional OS X, and it brings the two operating systems together in a few more ways too.
One of the biggest features in Yosemite is the ability for it to let you move your work between your Mac, iPhone, and iPad and then pick up exactly where you left off on another device. It also adds a few smaller — but still quite useful – integrations with iOS, such as the ability to send and receive text messages, to answer phone calls, and to automatically start up a wireless hotspot, should your phone plan support it.
At launch, the App Store appears to be having some amount of difficulty actually letting people start their download, but the page is up and offering the update nonetheless. OS X Mavericks has also been removed from the App Store and is no longer featured in the sidebar.
