Xeric Design’s dynamic desktop map software already lets you span the globe from your Mac. Now the latest version lets you span the globe across multiple displays.
EarthDesk replaces your static desktop with a detailed image of the Earth, showing current sun, moon and city illumination and real-time global cloud coverage. Unlike a screen saver, which only activates while your computer idles, EarthDesk continuously displays and updates its image of the Earth at all times as your desktop background—though it includes an option to be used as a screen saver as well.
EarthDesk 5.4, released Tuesday by Xeric, gains the ability to seamlessly span a map across multiple displays. Thanks to the feature, users can now take full advantage of the program’s detailed high-resolution maps.
EarthDesk requires OS X 10.5 or newer and sells for $25. Upgrade prices vary from $18 to free depending on your current EarthDesk version, so check the EarthDesk update page for your eligible price.
