What is it?

KeepingYouAwake is a menu bar utility for macOS 10.13 and newer that prevents the Mac from entering sleep mode, either for a predefined duration or for as long as it is activated. It is a lightweight wrapper around Apple's built-in caffeinate command line tool, which ships with all current macOS versions.

The app does not keep a closed-lid MacBook awake. Sleep prevention applies to desktop Macs and portable Macs with an open lid. The project is inspired by the older Caffeine app and was built as a replacement optimized for macOS Yosemite.

The app can be installed from the GitHub releases page or via Homebrew Cask with `brew install --cask keepingyouawake`. Older macOS versions are supported by earlier releases, which are linked from the project page.
