Automatically darkens macOS appearance and desktop picture in the nighttime. Runs, e.g., on my Mac mini 2010 with macOS High Sierra.

Getting started

To create an application from darkowlus.applescript, open it in Script-Editor, set your location, and export the modified script as stay-open application. Put the application into the darkowlus folder. Then put arbitrary desktop pictures Daytime.jpg and Nighttime.jpg into that folder, too, and run the application you created.

Thanks

This software uses sunrise-sunset.org API and includes the Night Owl from macOS App icons.
