Welcome to Amphetamine 4, the most awesome keep-awake utility ever created. 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.

It’s like Caffeine on steroids!

Except for a few very, VERY minor inconveniances (couldn’t for the life of me remember which of the default icons represented on and off afer I turned off the annoying notifications for manually disabling and enabling the app) which were easily remedied, this is the perfect stay awake app for your mac. Fantastic in it’s simplicity, yet with quite a few options for customisation if needed. It’s like Caffeine on steroids!

Greatest simplest app there is.. Does what it should, care free

Amphetamine has a quite good ring to it’s name; It makes the computer sleepless, as easy as popping a pill.
1 click and you’re there, with endless ways of tweaking and costumizing it’s schedule!

Very good

Excellent replacement for the Caffeine app which (sadly) is not updated anymore, as far as I know anyway.
Strongly recommended.
