KeepingYouAwake is a macOS utility app designed to prevent your Mac from sleeping. It provides an easy to use interface to quickly and easily set a timer, set hotkeys to keep the display awake, or even set a schedule for when your Mac should stay awake. The app also includes “Caffeine Mode” which is a feature that prevents the display from sleeping while the app is running. KeepingYouAwake is perfect for anyone who needs to keep their Mac awake for long periods of time, such as while running tutorials, streaming music, or doing any other tasks that require a lot of time.
Discontinued The program is no longer updated and does not seem to work. The latest version, 1.1.1, released in December 2010, can still be downloaded from the official website.
