How would anyone know who isn't running Yosemite that the image is not just some wallpaper pic of a mountain? All it says on the refurb page I bought it from is all the system goodies you get, not the OS.
Good question but there are four pictures of pictures of Yosemite National Park sites that are packaged with the OS. But a cursory glance at "About This Mac" would have revealed the OS version number.
