KeepingYouAwake
Caffeine alternative with dark mode support.
KeepingYouAwake is a menu‑bar utility for macOS 10.13 and newer that prevents the system from entering sleep mode. It can keep the Mac awake for a user‑specified time interval or indefinitely while the app remains active. The tool acts as a thin graphical wrapper around Apple’s built‑in `caffeinate` command, invoking the same functionality that ships with every macOS release.
The application is designed for users who need a simple way to stop automatic sleep during presentations, downloads, or other long‑running tasks, and it offers a dark‑mode interface to match modern macOS themes. It works on desktop Macs and on laptops only when the lid is open, respecting macOS thermal and hardware constraints.
KeepingYouAwake is open source, released under the MIT license, and can be installed directly from the project’s releases page or via Homebrew Cask. Contributions are welcomed according to the provided guidelines.
