About Amphetamine
Amphetamine is a macOS utility designed to keep your computer awake by overriding the system’s default sleep and screen saver behavior, giving users full control over when and how their Mac stays active. It operates through a simple on/off switch in the menu bar, allowing users to instantly start a “keep-awake” session that can run indefinitely, for a set duration, until a specific time, or while conditions such as file downloads or app usage are active. During these sessions, users can choose to prevent display sleep, disable the screen saver, keep the system awake even when the lid is closed, or allow selective behaviors like display sleep while the system continues running. One of its most powerful features is its automation system, which uses customizable triggers to activate or deactivate based on events such as connecting to Wi-Fi networks, using specific apps, plugging in external devices, reaching certain battery levels, or hitting CPU usage thresholds.
