Apples built in ‘Change picture – random order’ option for your desktop Pictures is great.
But what happens if you have more than one Screen/Monitor. Well each screen needs you to turn this on separately . And the pictures for each screen will be independently random from each other.
We can fix that using Applescript and LaunchAgents we can turn off the above and make each desktop picture change to a random image at a set interval and be the same image on each desktop.
Each desktop changes to the same image. If I switch to a new space on a desktop it’s image will change when the time comes.
