Sometimes I need to change the desktop for other purposes. So essentially I have two Automator workflows and two KM macros for the entire process. The macro triggers the change when ScreenFlow quits . When I’m done using ScreenFlow, I have another workflow and macro that change the image back to the desktop image I normally use. You can use any appropriate trigger (e.g., hotkey, stringer trigger) you like to run this workflow, but for this particular macro I use the application trigger, which means that when ScreenFlow launches, it changes to the desktop image I want to use for ScreenFlow recordings. Make sure that wherever you saved it, that KM can access it when the workflow runs. Click on the purple folder and locate the Automator workflow you just saved in your Applications folder.

I also issue a Dragon Dictate voice command to change from within any application, and I use an application trigger to make the desktop image change. Instead, I use an Automator workflow to quickly change between the two desktop images I use on a regular basis. While Mac OS X offers Spaces for quickly switching between desktops, I find Spaces a little cumbersome and impractical, especially since I work with a 27 inch iMac and a second monitor. Changing your desktop image can be hassle, but it doesn’t have to be if you know how to use Keyboard Maestro and Apple’s Automator.
