A free project called Afterglow lets modern macOS users run classic After Dark screensavers from the late 1980s and 1990s on current Macs, including macOS 27 Golden Gate.

Afterglow is a macOS app that emulates 68k module code to run After Dark screensavers without needing ROMs or old Mac OS dependencies.

John Gruber of Daring Fireball is cited as corroborating the release and the piece links to additional context about Afterglow and related projects.

The app provides access to original After Dark packs such as Flying Toasters, Boris the Cat, Mowin’ Man, and Bad Dog, with preserved audio and, in some cases, lyrics.

The article frames Afterglow as a nostalgic revival in retro computing circles and notes it’s easier to implement and more complete than previous web-based recreations of After Dark.

Developer Jeff Halter positions Afterglow within nostalgia-driven projects, alongside Lunacy and Stacks as part of an emulator-focused lineup.

The emulator is designed to run After Dark modules by preserving their original code rather than ports or remakes.

Users need the original After Dark files; Afterglow guides users to Internet Archive to download packs and install them via Afterglow’s Settings on macOS.

The piece is part of a broader tech-news roundup with coverage of Apple products from MacRumors, not focusing on unrelated topics.

Afterglow consolidates multiple After Dark packs, letting users choose and activate a wide range of retro screensavers on modern macOS.
