Xeric Design (http://www.xericdesign.com) has released EarthDesk 7, an update to its real-time dynamic desktop map for Mac OS X.

The app replaces your static desktop with an image of the Earth showing current sun, moon and city illumination, as well as real-time cloud coverage. A data subscription offers additional real-time information including earthquakes and named storms, allowing you to visualize hurricanes and other real-time events on your Mac.

EarthDesk 7 provides improved support for multiple screens and Retina displays. There are new positioning options including centering on a specific latitude/longitude or real-time data such as the location of the most recent earthquake. City labels now support multiple colors and different screens can show different sets of data. There’s a new city database with support for adding, editing and removing of cities. In version 7 presets are exportable to make it easier to move configurations between different Macs.

EarthDesk 7 requires Mac OS X Yosemite or El Capitan. It costs $24.99. Upgrades are available for $12.99 for licensed users of version 5 and 6. A data subscription adds high-resolution clouds, earthquakes, named storms and tacking of the International Space Station starting at $9.99 per year. Bundles that include EarthDesk and a discounted data subscription are available.
