Change OSX Wallpaper Mojave (Morning|Afternoon|Evening)

Here is apple script to change wallpaper on macosx based on time of day (Morning\Afternoon\Evening) You could put desired pictures in folders:

Create folders

bash: mkdir -pv '$HOME/Pictures/Wallpapers/Morning', '$HOME/Pictures/Wallpapers/Afternoon', '$HOME/Pictures/Wallpapers/Evening'

Run script : "osascript ~/$HOME/Pictures/Wallpapers/wallpaper.scpt"

Create cron task in terminal: crontab -e Copy without quotes: "30 * * * * osascript $HOME/Pictures/Wallpapers/wallpaper.scpt" #Run script every 30 min.

Crontab Help

Maybe better solution to use GUI Cron app: Cronnix
