macOS dark mode switcher script

Up: macOS

This toggles between light and dark mode, and sets the appropriate wallpaper — expects two image aliases light and dark, in ~/Pictures/System:

tell application "System Events"
 log "hello"
 tell appearance preferences
  set dark mode to not dark mode
  set isDark to dark mode
 end tell
end tell

if isDark is true then
 set pictureFile to (path to pictures folder from user domain as string) & "System:dark"
else
 set pictureFile to (path to pictures folder from user domain as string) & "System:light"
end if

tell application "Finder"
 set resolvedPath to ((original item of (pictureFile as alias)) as text)
end tell

tell application "System Events"
 tell every desktop
  set picture to resolvedPath
 end tell
end tell
