The general format for the solar metadata was as follows: ( ap = Mojave’s Dynamic Desktop FormatĪs it turns out though Mattt at NSHipster had done some digging around into the format for Mojave and that proved to be a good starting place.Įncoded within the heic file for the default dynamic wallpaper for Mojave was a metadata item named “solar”, which detailed the position of the sun in the sky in terms of its altitude and azimuth, for each of the images. So naturally I was excited to create my own dynamic desktops with this new style, but like with the previous ones, Apple hasn’t said anything about how one would go about doing that. I don’t use dark mode only at night 2, and so I’d often be left with a dark UI and a searing bright wallpaper. While I was enamoured with Mojave’s dynamic desktops at first, I ended up switching to a regular wallpaper after some time. This style is even acknowledged separately in System Preferences as “Automatic” rather than “Dynamic”.

Keeping with tradition macOS Catalina includes a new default wallpaper, and while it is a dynamic desktop, it works a bit differently: It only has two images rather than sixteen, and rather than switching between them based on time, the wallpaper is set based on whether your appearance preference is set to light or dark mode. Once enabled, a dynamic wallpaper would cycle between a number of related images 1, showing one that was appropriate for the time of day. To go with dark mode, macOS Mojave introduced a feature called “dynamic wallpapers”.
