NoSleep

NoSleep is a preference pane component bundled with the macOS system settings interface, and it appears to be discontinued — the search results indicate it has been abandoned and users are actively seeking alternatives. Since this is a system extension rather than a standalone application, it cannot be updated separately through the App Store or a vendor download page. Instead, any update would come from reinstalling or updating the parent system component itself. However, given that the developer appears to have stopped supporting NoSleep and Apple's own Energy Saver and now Battery Settings provide increasingly capable built-in sleep management, NoSleep will eventually become incompatible when Apple removes Rosetta 2 support in macOS 28 (September 2028) if no native update is released before then. For users who need simple sleep-prevention functionality beyond what macOS built-in settings offer, the community has migrated to Amphetamine, which is a free, actively maintained standalone application that runs natively on Apple Silicon and offers similar or enhanced control over Mac sleep behavior. Amphetamine is available from the Mac App Store and provides a more reliable path forward than waiting for a discontinued component to receive a native update.
