Insomniac

Insomniac for Mac is an intelligent anti-sleep tool for macOS.

That controls when your Mac stays awake through rules and scenario-driven methods. It is suitable for real-world work scenarios such as download tasks, external displays, Insomniac AirPlay playback, meeting schedules, long computing, and audio playback. It doesn’t simply block sleep for long periods, but monitors events through configuration files, automatically activates when conditions are met, and promptly exits when conditions change. The software offers built-in scenarios, a rule editor, and more than thirty triggers, supporting precise conditions by combining AND, OR, and NOT. Users can also add intelligent coverage rules such as battery, temperature, calendar, and scheduled time to avoid continuous wake-up during low battery or inappropriate conditions, maintaining a balance between automation and energy saving.
