This guide will show you have to install and run Mac Mojave wallpaper that changes after what time on the day it is. Every hour it will change.
First download the wallpaper and script from here: https://www.dropbox.com/s/8rps3p49mg3fkbc/mojave-background.tar.gz?dl=0
Next open the terminal and copy/paste;
cd && cd Downloads mkdir -p ~/Pictures/Wallpapers tar -xf mojave-background.tar.gz mv mojave-background ~/Pictures/Wallpapers io.elementary.code ~/Pictures/Wallpapers/mojave-background/mojave.xml
Now to the more tedious thing. In the script you’ll see the paths pointing to the wallpapers, but under my username: storm. Change all of them to your username. There’s quite a lot of editing to do.
When done go to System Settings and click on Desktop. Under Wallpaper click Import Photo… Go to ~/Pictures/Wallpapers/mojave-background and pick mojave.xml
Tested on: elementary OS 5.1.4
