I'm running Max OSX Mountain Lion, 10.8.4. I have tried several solutions to change the background image in every space/desktop, but can only get one. I have tried this shell script, have tried using Python's
appscript and have tried another shell script. It currently only changes the background in the current space.
This operation, changing the desktop background, can be done with a drag and drop method. However, I want to setup a cron job (or any other method) to have the wallpaper change randomly from images in a folder.
As of now, it looks like I just need to figure out how to access all desktops in
argparse, as it currently works with one desktop/space. Unfortunately, the documentation is rather poor.
