Override energy saver settings and keep your Mac awake.

Overview

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 intuitive and simple to use for those who don't need all the bells and whistles.

Click to Keep Your Mac Awake

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
  • While a file is downloading
  • While a specific app is running
Advanced Automation

Create a Trigger to automatically keep your Mac awake.

  • While an external display is connected
  • While a USB or Bluetooth device is connected
  • While a specific app is running
  • While a specific app is running and frontmost
  • While your Mac's battery is charging and/or when the battery is above a threshold
  • While your Mac's AC power adapter is connected
  • While your Mac has a specific IP address
  • While your Mac is on a specific WiFi network
  • While your Mac is connected to a VPN service
  • While headphones or another audio output is in use
  • While a specific drive or volume is mounted
  • While your Mac's CPU is being utilized to a specific threshold
What's the Catch? No catch.

Amphetamine is 100% free. It's a gift from me, to you. Enjoy!

  • No in-app purchases
  • Nothing to unlock/no "pro" version
  • No annoying prompts asking you to review Amphetamine
  • No links for other paid apps
  • No tracking
  • No data-harvesting

  • Hot key support for starting/ending sessions

Love the name, love the icon. Don't have a sense of humor? No 'tongue in cheek' for you? Then don't come to the software's download page.

Yes, of course. You comment is obviously sarcastic, but indeed, I do my best to test each build before it is released. The truth is, I am a human and I do make mistakes. When I make them, I try to fix them as soon as possible, so that you, the person to whom I freely give this software I have built, can have a better experience. Amphetamine is a side project for me, but as I mentioned before, I do try my best to deliver a bug-free app. If you would like to help me beta test, please contact me via Twitter @AmphetamineApp. It's quite a challenge to test every combination of Amphetamine's functions, for every supported version of macOS, all by myself.

I love this app, but the only feature I feel it's missing is the ability to permanently add applications to the white list. Otherwise, the features are rich, and it's very well designed and thought out; I love it much more than any other similar app I've used in the past. My only other suggestion is: charge a few dollars for it; it's worth at least $5. Give me an app white list that prevents sleep, and I'll update to 5 ⭐️. Great work!

I realized after posting this review the Trigger list does in fact contain a white list for apps. Thank you!

Waiting to see if i can get an apparent permissions drawback overcome. My system won't let me choose the external backup drive used for time machine to stay awake (because it causes my whole system/imac to stall/lag/freeze .... i guess it's the external drive, that's what i've analyzed it to so far).

One of the positive/different things about keep drive spinning is it allows me to use admin pw to force KDS to choose the external drive. i filed a support request w/ amphetamine cuz i would like to try it and see if it's indeed better as so many reviews say. Thanks. will plan to update once I find out.

UPDATE: Boy that was quick! They responded almost immediately and told me to do this:

Try creating a new folder at the root of the drive for use with Drive Alive. Then, select the folder instead of the root of the drive.

It worked! I named my emply folder > Amphetamine Keep Alive My Drive, which i was able to choose in Amphetamine preferences > Drive Alive.

So, that barrier was defeated (easily) and now I'm going to be testing it and comparing experiences. Will review later.

Hope this may help others. Cheers!

Update: I had issues with this working correctly on my Mac mini, and ended up migrating to Theine (which is on the Mac App Store for 99¢ [though I downloaded when it was free]) which for some reason is not listed in MacUpdate. http://www.ixeau.com/apps/theine/

Some of the preferences not saving is a bug in 3.0. The 3.0.1 update should resolve the issue (fingers crossed). For your other issue, I'd need to work with you directly to better understand the issue. You can submit a support ticket here: https://instinctualflaw.uservoice.com/

This is really really excellent, great scriptability for automating its use and lots of control/triggers etc. So good I'll even brave the App Store for it...

Maybe someday. Distribution and maintenance of 2 version is the biggest issue with this. If I ever create a non-App Store version, there's going to be some neat features added. ;)
