Using Dynamic Desktop Mode in
24 Hour Wallpaper


Dynamic Desktop mode in 24 Hour Wallpaper allows you to use macOS’s native Dynamic Desktop feature to manage our wallpapers. This may be optimal for people who do not or can not run a helper app, or who simply prefer to do things the pure Apple way. If you have reviewed the information here and are still having issues please contact is at support@magicwindowapp.com.

Dynamic Desktop is a new feature from apple and has a variety of bugs you may encounter. There are also a few behaviors that might surprise you. In this document we’ve done our best to cover the most common situations. If you are unable to get the Dynamic Desktop mode to work right for you please e-mail us.

Please update to version 2.0.2

Check for the update in the Updates tab in the Mac App Store. If you don’t see it yet please be patient, it can take a moment for it to circulate around all of Apple’s servers.

If you have not already done so please upgrade to 24 Hour Wallpaper version 2.0.2. It fixes a bug in the Dynamic Desktop generator. The app will prompt affected users to update their Dynamic Desktops on launch. This affects every users outside of the Pacific time zone.

Common issue #1a:
In Dynamic Desktop mode, in Dark Mode, the wallpaper stays dark.

Common issue #1b:
In Dynamic Desktop mode, the wallpaper stays light.

In order for Dynamic Desktop mode to work, your Mojave Dynamic Desktop needs to be set to “Dynamic” and not “Light” or “Dark.” macOS will automatically set this to “Dark” the first time you enter Dark Mode. This is very confusing. If your wallpaper is stuck light, or stuck dark, please follow these steps:

  1. Open System Preferences

  2. Select Desktop & Screen Saver

  3. Select the default Mojave Dynamic Desktop wallpaper

  4. Select “Dynamic” in the drop down next to the thumbnail (screenshot below)
    This drop down may appear scrambled if you are in Dark Mode

  5. Select Refresh Desktop from the 24 Hour Wallpaper menu bar menu (screenshot below)

  First, select the Mojave default wallpaper and select “Dynamic.”  This overrides macOS’s decision to make the desktop dark only.

  Second, select Refresh Desktop from the menu bar menu.  If you have multiple monitors you will see this option under the name of your display.

Common Issue #2:
I tried the above steps and the wallpaper is still stuck.

Please try restarting your Mac. Dynamic Desktop can get “stuck” such that it is only showing the cover image of the wallpaper. This happens just as much with Apple’s wallpapers as ours. In this situation the only guaranteed way to resolve it is to restart your Mac. We have seen it fixed sometimes by logging out and back in, but not always.

Common Issue #3:
The wallpaper changes but it’s not quite in sync with my time.

Dynamic Desktop is a bit of a black box. We have done our best to generate these wallpapers based on what we know about it, but there are certainly going to be situations that are not accurate. If you’re experiencing consistent inaccuracy please e-mail us at contact@magicwindowapp.com and let us know. You can also adjust the time settings in 24 Hour Wallpaper Preferences. However if you have Dynamic Desktop mode on, the settings only apply when the wallpaper is generated.

Dynamic Desktop is non-deterministic. We can not guarantee that it will update or show a particular image at an exact time. It does offer a good, workable experience. If you want to experience the scenes match time exactly as we intend, don’t use Dynamic Desktop mode.

Common Questions:
Once a Dynamic Desktop is set, do I need to be running the app?
Can I extract the wallpapers?

No, you do not need to be running the app in Dynamic Desktop mode once the wallpaper is generated. Once setting a Dynamic Desktop in the app watch for the Menu Bar Icon to finish animating. Once that is done that’s the sign you can quit and the wallpaper will work.

Yes, you can just extract the wallpapers. However the app is designed such that you shouldn’t need to. Just set the wallpapers you want and then quit the app.

If you really want to extract the wallpapers here’s how.

  1. Enable Dynamic Desktop Mode in Settings under the Dynamic Desktop tab.

  2. Set the wallpapers you want Dynamic Desktops for.
    You’ll need to wait for the app to finish generating the dynamic desktops.

  3. Once the app has generated the desktops you want, you can open the following folder in finder:

    ~/Library/Containers/com.jetson.24hourwallpaper/Data/Library/Application Support/24 Hour Wallpaper/Scenes/

    The easiest way to do this is to open Finder, open the Go menu, and select Go To Folder….
    Note that the “~” represents your home directory.

  4. In this folder you will find a folder for each scene, and in that scenes folder you will find a folder named DynamicDesktop. Grab the file you want from the appropriate resolution folder in the DynamicDesktop folder (e.g. 5120x2880). If you need a different resolution you’ll need to change resolution in Settings and start over.
