OS X 10.9 Mavericks was only available as an upgrade through the Mac App Store and was offered as a nil-cost upgrade to Apple OS X users as far back as OS X 10.6 Snow Leopard. OS X 10.8 Mountain Lion was only available as an upgrade through the Mac App Store and cost £13.99 in the UK. Way back in October 2009, OS X 10.6 Snow Leopard was delivered via DVD and cost £25 in the UK when launched.Īpple stopped supplying DVDs with the release of OS X 10.7 Lion (though it was available for a short time on a USB drive) and cost £20.99 in the UK, preferring a download delivery model via the new Mac App Store, instead. In this tutorial, I'll show you what you will need to do to ensure that a Mac is ready for upgrade, from OS X 10.9 Mavericks, or earlier, to OS X 10.10 Yosemite when it is released later this year. OS X 10.10 will be known as Yosemite, named after the Yosemite National Park in California. The second in a departure from the previous naming system of big cats, the next iteration of OS X, being 10.10, will start a new naming convention taken from places in California.

Apple announced the latest version of it’s OS X operating system, on the 2nd June 2014, at the Worldwide Developers Conference (WWDC) in San Francisco.
