description: "A native Swift player that runs Lunatic Fringe, the interactive After Dark space-shooter screensaver from the early '90s, unmodified on modern macOS."
---

Lunatic Fringe was a hidden game inside Apple's More After Dark package: toggle caps lock while the screensaver ran and it dropped you into a space shooter with power-ups and a high-score chase. Lunacy is a native Swift player with a built-in emulation engine that runs that original module, unchanged — you supply your own copy of the module, drag it onto the app, and it plays at full screen with an optional CRT shader. It requires macOS 13 Ventura or later and ships as a universal binary, currently at v1.1.1.
