Show HN: I reverse engineered Apple's video wallpapers
On May 20, 2026, a developer unveiled 'Phosphene' on Hacker News, a new open-source project hosted on GitHub that successfully reverse-engineers Apple's proprietary video wallpaper format. This technical achievement allows users to generate their own dynamic wallpapers for macOS, mimicking the sophisticated visual transitions and effects found in Apple's official offerings. The project's release under the 'Show HN' banner signifies its novelty and community interest, providing a detailed look into the previously opaque mechanisms behind macOS's dynamic desktop feature. 'Phosphene' offers a practical utility for macOS users seeking more control over their desktop aesthetics. By making the underlying format accessible, the project empowers developers and enthusiasts to design and implement custom video wallpapers, moving beyond the limited selection provided by Apple. This initiative fosters a more vibrant ecosystem for macOS personalization, potentially leading to a wider array of community-contributed dynamic wallpapers.
Developers can now create and distribute custom dynamic video wallpapers for macOS, expanding personalization options beyond Apple's official offerings.
