Welcome to Amphetamine 4, the most awesome keep-awake utility ever created for macOS. Amphetamine can keep your Mac, and optionally its display, awake through a super simple on/off switch, or automatically through easy-to-configure Triggers. Amphetamine is extremely powerful and includes advanced features for those who need them, yet remains super intuitive and simple to use for those who don't need all the bells and whistles.

I used to use the Caffeine app. Unfortunately, that one doesn't work on Mojave. This app (Amphetamine) is an even better alternative, with more customization options. Love it!

This app should be in all operatings systems. By default. This is a must have. I especially like the “while app is running” setting. Thanks William.

Contact support if you need assistance. A one star review won’t solve anything. ❤️
