Welcome to Amphetamine, the most awesome keep-awake app ever created for macOS. Amphetamine can keep your Mac, and optionally its display(s), 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 easy-to-use for those who don't need all of 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

During a keep-awake session, choose to allow or prevent:

• Display sleep
• Screen saver activation
• System sleep when built-in display is closed
• Automated mouse cursor movement
• Locking of the screen

=== Advanced Automation ===

Create a Trigger to automatically keep your Mac awake.

• While an external display is connected
• While your Mac's display is being mirrored
• While a USB or Bluetooth device is connected
• While a specific app is running

• While your Mac's battery is charging and/or when the battery is above a threshold

No catch. Amphetamine is 100% free. It's a gift from me to you. Enjoy!

What’s New

Version 5.3.2

=== Introducing Power Protect ===

In Amphetamine 5.3, a Closed-Display Mode script was introduced to address an issue on Apple Silicon Macs where connecting or disconnecting your Mac laptop from an external power source could cause unexpected session behavior. Running this script required use of Touch ID or an administrator's password.

Thanks to members of the Amphetamine community (Pitor and Joe), a way to run the script without authentication has been identified and implemented in Amphetamine 5.3.1. To run the script without authentication, you must download and install both the script and a configuration file. This feature is now known as Power Protect and is only needed/available on Apple Silicon Mac laptops.

Please note that Power Protect is not included directly in Amphetamine and requires a separate download and installation. When you start a Closed-Display Mode session on an Apple Silicon Mac, Amphetamine will ask you if you would like to Learn More about Power Protect. If you choose Learn More, you will be directed to a website where you can read about Power Protect and choose to install it, if desired.

=== Fixes ===

• Fixed a crash on macOS Sonoma related to Bluetooth privacy settings access

• Added warning when Amphetamine is running using Rosetta

• Fixed an issue where some Apple Silicon Macs could be identified as Intel

• Fixed an issue for sessions that start at app launch don't enable Closed-Display Mode

• Fixed an issue where the session time remaining or other text would overlap Amphetamine's icon in the menu bar

• Fixed an issue with a -50 Application Can't be Opened error that appeared on some older macOS versions

• Added additional logic/code around creating and releasing power assertions in an attempt to fix an issue where Amphetamine causes a Mac to sleep, disconnect from external displays and/or WiFi, or create a "flash" on external displays

• Added ability to uninstall scripts via Amphetamine (menu bar icon) → Feedback & Support → Uninstall Scripts...

• Added Location Services request for current WiFi network name access for Trigger sessions in macOS Sonoma

• Configured all of Amphetamine's alerts to be floating windows (show on top of other windows)

• Fixed an issue where some menu text was clipped in French localization

• Fixed an issue with Triggers not activating on some non-laptop Macs

• Fixed an issue where some IP address-based Trigger sessions would not end when expected

• Added Debug Mode

Top Fix for Mac's shortcomings

Thank goodness there a clever people out there that can make up for what Apple doesn't do. While appreciate what Apple does to cover the lowest common denominator and make life as 'think' free as possible, it shoud at least provide the options for those that do want a choice in how they customize their devices. Thankfully, this app has made customization of wether I choose to have the lid open or closed and still operate a very simple task in choosing. Thank you devs. Bit of a hassle having to walk around the block a few times to get it fully operational but I'm grateful. And at this price ! Wow. I would have paid. I'll donate that cup of coffee at least anyway. Cheers

Customisable, does job well, notifications,Great

There are others which are available free, but this one is better. I tried “caffiene” previously but that is not much customizable. Amphetamine, I can customise notifications, set notifications every 5 or 10 or 60 minutes and much muc more.
I hope this app does not meet the same fate of several other apps that had their support simply ‘discontinued’ by their developers. “iClipboard”(from Chronos) was one such app. Best of the best of the best, yet its support has been discontinued. What a loss.

An absolute lifesaver utility

You've done an amazing job dev. Couldn't ask for more. Mac users are lucky to have this available to them. Thank you for making it free!

Edit: I think the name and branding of the app is acceptable. I don't think it goes against the guidelines and the branding for the app does make sense. My vote is that Apple should not ask the developer to change it.
