Mac OS X has always offered enchanting background images. I’ve been very fond of Apple’s blue arches, northern lights, galaxies and mountain terrains.
One of the newest stands out from the rest. It’s available in System Preferences, named El Capitan 2. It’s of Yosemite National Park at night, revealing an array of starry night lights above the mountain peaks.
This, I contend, is the most faithful photographic representation of OS X’s default wallpaper themes wrapped into one. It features lots of blue (which reflects the early Aqua themed wallpapers of Tiger, Jaguar and the like), starry skies and nature all in one.
