Script downloads current Bing Daily Wallpaper to ~/Pictures/bing-wallpapers/ and sets it as wallpaper on all your monitors.

1. Copy com.bing-wallpaper-daily-mac-multimonitor.plist to ~/Library/LaunchAgents/

2. Copy bing-wallpaper.sh to ~/bing-wallpaper.sh

3. Run launchctl load -w ~/Library/LaunchAgents/com.bing-wallpaper-daily-mac-multimonitor.plist in terminal (it can ask for permitions for the first time)

Tip: use com.bing-wallpaper-daily-mac-multimonitor-uhd.plistfor UHD 4K images Tip: provide parameter -m <monitor number> to bing-wallpaper.sh in appropriate .plist file to set wallpaper only on certain monitor

Script bing-wallpaper.sh is run every 30 minutes and checks if there is a new image on Bing.com. New image is downloaded and set as desktop picture on your all monitors.

Optionally you can edit com.bing-wallpaper-daily-mac-multimonitor.plist file to run script in different interval or schedule runs on specific time of day. (run launchctl unload -w ~/Library/LaunchAgents/com.bing-wallpaper-daily-mac-multimonitor.plist edit plist file and again load it)
