Description

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.

What Apple Should Have Done, and More

Big thanks to the lone wolf who developed Amphetamine, and made it available for free. Haven’t encountered any issues at all.

Righteous successor to Caffeine

Caffeine’s been the de facto sleep killing app for a long time, but it’s been all but abandoned for about 5 years. Found this app going through potential replacements and gave it a spin. It’s just plain great! It’s highly flexible, customizable and holy gouda it’s free!

I’ve had no issues with it and I’ve installed it on all my Macs. Absolutely worth it.

Was a long Caffeine user.
Amphetamine is way better with more choices.
Keeping Drives awake is awesome!

Thank you for your great work
