To start, however, let’s actually download a couple of image collections, New York City and San Francisco, from the 24 Hour Wallpaper archive. Me? I actually have 24 Hour Wallpaper running on my computer and have become quite a fan of the handy utility. A bit more flexible, but it is running all the time (even if it’s just sitting and waiting for specific time-based triggers to rotate wallpapers) which some people don’t like much. The other possibility is through running third party software like 24 Hour Wallpaper, which will work correctly regardless of what version of MacOS X you’re running. You can add third-party desktops and use the Mac system to change them as needed. MacOS X Mojave (10.14.*) introduced system dynamic desktop wallpapers but only ships with two options.

There are two primary ways you can set up a dynamic desktop on your MacOS X system, depending on what operating system you’re running and your aversion to having third party apps always running in the background.
