How do I get the official Yosemite desktop background?
I upgraded to Yosemite, but after all was installed & my MacBook Pro restarted, I'm still getting the Mavericks desktop background. All else looks like Yosemite, so it appears that the upgrade was successful. Has anyone else experienced this? Any idea how to get the cool Yosemite wallpaper? The update added 3 new images of the park in my desktop pictures folder, but none of them is the closeup of Half Dome wreathed in clouds that's the official image for Yosemite.
MacBook Pro (15-inch Late 2008), OS X Yosemite (10.10)
