AwakeBar

AwakeBar is a lightweight anti-sleep tool that runs in the macOS menu bar.

Suitable for presentations, online video streaming, long downloads, code building, data processing, and other scenarios where your Mac needs to remain running. The application requires no Dock icon or main window; simply click the menu bar icon to open the control panel and quickly select a duration of 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, or unlimited. You can also customize the wake-up time by hour and minute. AwakeBar can simultaneously maintain both the display and system operation and offers an option to lock the screen, keeping your device working without sacrificing basic security. The application supports quick switching with an Option click, automatic startup on login, and can attempt to override power policies on managed devices, automatically pausing in low-power mode to prevent continuous power drain. MacBook users can also use options to prevent sleep when the lid is closed. The software runs completely offline, does not collect, store, or transfer personal data, and does not access microphone, camera, or location information.
