Description

Welcome to Amphetamine⁴, 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.

Quickly start a keep-awake session from Amphetamine's menu to keep your Mac awake.

• Indefinitely, for a specified amount of time, or until a specified time

Requesting to add an important feature !!

I am using Amphetamine for a while and I kinda love using it !! It’s best for iMacs , Mac Mini and the Mac Pro , but Amphetamine is’nt yet laptop ready ,, when ever I turn down the lid the my MacBook Air goes to sleep even if Amphetamine has a session opened !! May be it’s there but I could’nt find it ,, I’ll check it out and if it’s not there I plead to get this added ,, its so kind of you that you gave us such a powerfull app for free ,, thank you !!! I consider this feature to be the one and only missing feature in Amphetamine ,, It would be great to see laptop lid closing sleep problem fixed soon !!!

Awesome app

I have been using this since the day I got my macbook air. Simple yet awesome.
Recent update has brought in one issue. Notification sounds are not working post update. I tried changing sound gettings etc but still no sound. Quick search on google shows that multiple folks have hit this issue.
I have removed one star because of this issue else it deserves 5 stars

Developer Response ,

Update to version 4.1+ and you can enable sounds again.
