Keeps your Mac awake on your terms — precise triggers for time, running apps, network, battery, or an attached display, all from the menu bar.
Amphetamine stops your Mac from sleeping, dimming, or starting the screen saver for as long as you want. Start a quick session from the menu bar, or set up Triggers that keep the Mac awake automatically under conditions you define.
Why it makes the list
The built-in prevent-sleep options are blunt. Amphetamine is the powerful, genuinely free version: session timers, indefinite sessions, and a rich Triggers engine — stay awake while a specific app runs, while a drive is mounted, while on a particular Wi-Fi network, while the battery is above a threshold.
