Common Questions & Issues
The current version of 24 Hour Wallpaper is fully compatible with the latest updates to macOS Mojave and macOS Catalina. It remains compatible with all releases of macOS High Sierra, macOS Sierra, and macOS El Capitan. If you experience any issues after updating please contact us at firstname.lastname@example.org.
Common issue #1: Glitching and shadows appear on the right edge of the wallpaper
We have found a bug in macOS High Sierra and Mojave that affects iMac computers model years 2011-2013 with NVIDIA graphics cards. The bug is with the macOS HEIC format encoder/decoder for NVIDIA. We have added a “Graphics Compatibility Mode” that uses JPG which fixes the issue. If you have this issue please contact us at email@example.com and we will provide you with the fix. Thanks for your patience.
Common issue #2: Scene downloads are slow
If you experience slow scene downloads we recommend you try a different download server. Open 24 Hour Wallpaper Preferences, select the Downloads tab, and pick “CloudFront” as your server. If you do not see improved performance, you can try the other servers as well. If they are all slow, check your network connection.
Common issue #3a: In Dynamic Desktop mode, in Dark Mode, the wallpaper stays dark.
Common issue #3b: 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:
Open System Preferences
Select Desktop & Screen Saver
Select the default Mojave Dynamic Desktop wallpaper
Select “Dynamic” in the drop down next to the thumbnail (screenshot below)
This drop down may appear scrambled if you are in Dark Mode
Select Refresh Desktop from the 24 Hour Wallpaper menu bar menu (screenshot below)
Common issue #4: Wallpaper does not set
After pressing "Set Wallpaper" in the scene browser you may experience a situation where the wallpaper does not actually get set. The most common cause of this is existing wallpaper settings which select a color instead of image as wallpaper. It can also happen as the result of an OS bug. To resolve the problem:
Open System Preferences
Open System Wallpaper
Select Desktop Pictures folder
Select an image as your wallpaper
Press Set as Wallpaper in 24 Hour Wallpaper again
Common issue #5: Wallpaper disappears (typically after display connect/disconnect)
You may find the wallpaper disappears on one display, becomes gray, or reverts to the macOS default system wallpaper particularly after connecting or disconnecting a display. When this happens the wallpaper may appear momentarily and fade in/out, but does not stay around on the desktop. This is an indication of the same issue described above. Follow the same steps as for issue #1.
Common issue #6: Wallpaper stops updating
You may find that the wallpaper stops updating to mach the time of day. Most commonly this is caused by the app not running. Make sure 24 Hour Wallpaper is running - you can open it from the Applications folder. If the app is running but not updating, try selecting a different scene. This will usually resolve the issue.
Common issue #7: Wallpaper resolution is too low
By default 24 Hour Wallpaper will download images at the optimal resolution for the highest resolution display connected to your Mac. The maximum supported resolution is 5K (5120x2880). You can change this setting in 24 Hour Wallpaper Preferences under the "Downloads" tab. If you connect a display that is higher resolution that one previously connected you will need to adjust this setting.
Common issue #8: Incorrect location
24 Hour Wallpaper needs to know your location to align the wallpaper to your time of day. If you accept permissions for location when the app first starts the app will try to get your location automatically. If you don't accept permissions or have WiFi disabled, you will need to manually enter your location. To do this click "Choose..." in 24 Hour Wallpaper Preferences under the "Place & Time" tab.
Common Question #1: Can I run 24 Hour Wallpaper and Magic Window together?
If you are a Magic Window user you may need to make some adjustments to make sure that 24 Hour Wallpaper does not conflict. We offer a complete guide on using Magic Window and 24 Hour Wallpaper together. We encourage you to read the guide. Below are the highlights.
If you want to run the Magic Window screen saver with 24hr Wallpaper we recommend you use the system screen saver plug-in. You can download the plug-in here. This is how we do it. You don't need to be running the app with this plug-in.
If you want to use the Magic Window app screen saver instead you can open Magic Window preferences and uncheck "Enable Timelapse Wallpaper on Desktop."
If you were running Magic Window and no longer want to use it be sure to disable the "Open at Login" option in Magic Window preferences.
To run Magic Window on one display and 24 Hour Wallpaper on another first disable the "Hide system wallpaper with black color" option in Magic Window. Then in each app disable opposing displays from the menu bar menu. This should work, but there could be edge cases where there are problems. If you have issues please contact us.
Common Question #2: Can I stretch one wallpaper across multiple monitors?
It is now possible to stretch one wallpaper across any configuration of monitors using the app Multi Monitor Wallpaper. It is available in the Mac App Store as a free trial and works perfectly with 24 Hour Wallpaper.
To use 24 Hour Wallpaper with Multi Monitor Wallpaper:
Get Multi Monitor Wallpaper from the Mac App Store
Open 24 Hour Wallpaper
Open 24 Hour Wallpaper preferences and select the Dynamic Desktop tab
Enable Dynamic Desktop mode
Wait for the Dynamic Desktop to generate - this can take a few minutes. The menu bar icon will animate until the generation is done.
When Dynamic Desktop generation is complete, open System Preferences -> Desktop & Screen Saver and select the Desktop tab.
Open Multi Monitor Wallpaper side-by-side with System Preferences
Drag the wallpaper thumbnail (showing Mojave) from System Preferences to Multi Monitor Wallpaper. See screen-shot below.
Follow the process in Multi Monitor wallpaper to generate and set your wallpaper.
Quit 24 Hour Wallpaper - Important, if you do not quit the app, it will over-write the wallpaper.
