How to create custom dynamic wallpapers for macOS Mojave
Dynamic wallpapers is a new cosmetic feature introduced in Mojave. It has some utility to it but that depends on the wallpaper you’re using. Dynamic wallpapers are images that transition from day to night time as the day progresses. The image is several images that are different to suit the time of day. Out of the box, Mojave only has one dynamic wallpaper. Here’s how you can create your own custom dynamic wallpapers for macOS Mojave.
Images for dynamic wallpapers
You will need images for the dynamic wallpaper and that really is the hard part. You don’t necessarily have to use landscapes for it. If you’re skilled at creating graphics, you can probably create one yourself that doesn’t use a landscape.
Custom dynamic wallpapers
Creating a custom dynamic wallpaper isn’t easy unless you use an app for it. We recommend the Dynamic Wallpaper Club app. It is, by far, the easiest way to create custom dynamic wallpapers for free, and without any watermarks.
In order to use this app you need to create an account, and you will need to use Safari to download the wallpaper. You can create it in any browser but it appears to only download in Safari.
Prepping images
Put all your images in one folder. To make things easier, give them numerical names and in the order you want them to change e.g. the early morning image should be named 1. The images should not be larger than 15MB.
Create wallpaper
Visit Dynamic Wallpaper Club and click the Create button at the top. Drag and drop the files that you want to use for your wallpaper. Give it a name, and a tag if you want. Select the mode from the left. It’s a good idea to go with Time mode. You won’t have to set the time yourself.
Once the images have been uploaded, confirm that you’re authorized to use them and then click the Create button. You will be redirected to your profile while the wallpaper processes. It can take a while, depending on the number of images you uploaded. Once it is complete, visit the wallpaper and click the download button.
The wallpaper will download as an HEIC file and that is your dynamic wallpaper.
Set dynamic wallpaper
Open System Preferences and go to the Desktop & Screensaver preference. Select the file you downloaded. Unfortunately, dynamic wallpapers don’t show a preview like the static images do. You will have to guess which image is the one you want to use. Alternatively, you can put each dynamic wallpaper you create in its own folder so that you know which is which.
