KeepingYouAwake is a macOS menu bar utility that prevents a Mac from automatically entering sleep mode. It offers both manual and timed control, allowing users to keep their system awake with a single click from the menu bar or for a user-defined duration that automatically reverts upon expiry.
The utility distinguishes itself through battery-aware operation, automatically disabling sleep prevention when the battery level drops below a configurable threshold to conserve power. This combines with a lightweight menu bar interface that provides instant activation and deactivation of sleep prevention without opening a separate window.
The application integrates with macOS power management frameworks to assert or release sleep prevention locks, supporting both indefinite manual prevention and scheduled countdown timers. It continuously monitors battery levels via system APIs to trigger automatic deactivation when power runs low.
