Using Dynamic Desktop Mode
in 24 Hour Wallpaper


Dynamic Desktop mode allows you to use our wallpapers as native macOS Dynamic Desktops. This may be optimal for people who can not or do not want to run a helper app. With this mode enabled, once a wallpaper is set and generated you can quit the app. It can take 1-2 minutes to generate a Dynamic Desktop.

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 have reviewed the information here and are still having issues please contact is at support@magicwindowapp.com.

Pro tip: Our built-in wallpaper format is higher quality and more accurate than Apple’s Dynamic Desktop format. If you want the best experience using our wallpapers don’t use Dynamic Desktop mode unless needed. We understand there are good reasons to use this mode which is why we offer this feature.

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.

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.

When Dynamic Desktop mode is off, the app will always sync the wallpaper with time whether you are in light or dark mode. It is only in Dynamic Desktop mode where this problem may occur.

 

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:
Why is so much CPU/GPU used by Dynamic Desktop mode?
Why is my laptop running hot with this enabled?

When Dynamic Desktop mode is enabled the app hands the wallpaper images over to Apple’s API to generate a Dynamic Desktop format wallpaper. This is a very CPU/GPU intensive activity and Apple’s API does not provide any indication of how much progress has been made or how much time is left. While the wallpaper is generated large amounts of CPU and GPU will be used. This process takes 1-2 minutes, after which no CPU/GPU usage is required. The menu bar icon will animate until the process is complete.

Common Issue #4:
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?

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.
