Lungo

About Lungo

Lungo prevents a Mac from sleeping or dimming while its keep-awake mode is enabled. It is useful when you need a display to remain visible during a presentation, a reading session or another task with little keyboard input.

Choose a short interval and check what happens when it ends. Use the setting that fits your task so the Mac can return to its normal sleep behavior afterward, especially if you are running on battery. A timed setting can help if you need the screen for a task but regularly forget to change system settings back.
