Apple introduced OS X Yosemite, the latest major release of its operating system, on Thursday. Yosemite is now available as a free upgrade from the Mac App Store. The new operating system supports all Macs introduced in 2009 or later, and some models introduced in 2007 and 2008. Here is Yahoo Tech’s David Pogue talking about Yosemite in a video. You may also find this article by Jason Parker of CNET talking about the new features of Yosemite interesting.
