If you’re a Mac user who frequently needs to keep your computer awake without constantly interacting with it, then Amphetamine is an app worth exploring. In today’s productivity-driven world, your Mac’s tendency to automatically go to sleep, dim the display, or start a screen saver can be a barrier to achieving uninterrupted work. Thankfully, the Amphetamine app offers a solution. This trusted and highly-rated utility allows fine-tuned control over your Mac’s sleep behavior, ensuring your system stays active for precisely as long as you need.
What Is Amphetamine?
Amphetamine is a free, lightweight application developed exclusively for macOS that prevents your Mac from going into sleep mode. Developed by William Gustafson, the app is available via the Mac App Store and has garnered praise for its minimalistic interface and robust suite of features.
Unlike temporary workarounds or terminal commands, Amphetamine is user-friendly and feature-rich right out of the box, eliminating complicated configurations or system alterations.
Why Use Amphetamine?
The auto-sleep feature on macOS is essential for energy efficiency, but there are numerous legitimate cases where keeping your Mac awake is necessary. Common scenarios include:
- Running long downloads or uploads
- Using Mac as a server or screen-sharing host
- Rendering video or performing other resource-intensive tasks
- Preventing sleep during presentations or screen recordings
- Running tests or installations that require continuous operation
In these cases, Amphetamine provides peace of mind and ensures that operations are not interrupted by system timeouts.
Key Features of Amphetamine
What makes Amphetamine stand out from other keep-awake tools is the granularity of control it offers. Here are some of its most noteworthy features:
1. Trigger-Driven Activation
Amphetamine lets users create custom triggers based on:
- Opened or closed applications
- Network conditions (e.g., connected to a specific Wi-Fi network)
- External displays or drives being connected
- System battery status or power adapter
- Specific timeframes
These triggers allow the app to work in the background with minimal intervention.
2. Session Timing
Users can define fixed or indefinite durations for keeping the Mac awake. Choose to keep your Mac awake for 15 minutes, 5 hours, or indefinitely — you’re in full control.
3. Menu Bar Integration
The app sits quietly in the macOS menu bar. Its clean and intuitive dropdown menu provides quick access to session options, settings, and active triggers.
4. AppleScript and Automation Support
For advanced users, Amphetamine supports AppleScript. This makes it easy to integrate into automated macOS workflows using apps like Automator or Shortcuts.
5. Display Sleep Control
Amphetamine allows the computer to stay awake while still dimming or turning off the display — perfect when you don’t need the screen on but want the Mac to continue tasks in the background.
6. Notifications & Feedback
The app provides feedback via sound and notification banners, informing you when a session begins, ends, or has been paused due to particular triggers.

How to Install and Use Amphetamine
The installation process is straightforward:
- Open the Mac App Store
- Search for “Amphetamine” by William Gustafson
- Click “Download” or “Get” to install the app
Once installed:
- Launch Amphetamine via your Applications folder or Spotlight
- The icon (a pill capsule) appears in your menu bar

Security and Privacy Considerations
Given the growing concern over software privacy, especially those that interact deeply with system settings, it’s natural to question the safety of apps like Amphetamine. The good news is that Amphetamine is Apple notarized and does not require elevated system permissions to run. It does not collect personal data or transmit information over the internet. The app’s open and consistent update history has further contributed to its trusted status.
Moreover, since Amphetamine is distributed via the official Mac App Store, it aligns with Apple’s rigorous app review process regarding privacy and performance standards.
Comparison with Alternatives
There are other Mac sleeping-prevention apps out there, including:
- Caffeine: One of the original keep-awake utilities for Mac, though it is no longer actively maintained.
- KeepingYouAwake: Open-source and similar in function, but lacks some of the automation features Amphetamine offers.
- Manual Settings: macOS users can manually prevent sleep via Energy Saver preferences or terminal commands, but this lacks flexibility and convenience.
While each alternative has valid use cases, Amphetamine remains the most robust option — balancing an easy-to-use interface with professional-grade features.
Amphetamine’s Compliance With App Store Guidelines
In a notable incident in early 2021, Apple briefly threatened to remove Amphetamine from the App Store, misinterpreting the app’s branding relating to drug terminology. However, the issue was resolved professionally and the app remains live and fully approved. The developer has clarified that the app’s name is metaphorical, referring simply to its function of ‘keeping awake.’
This episode highlighted not only the clarity of Apple’s branding restrictions but also the developer’s diligence in maintaining compliance, integrity, and transparency.
Best Practices for Using Amphetamine
Although Amphetamine is immensely helpful, its inappropriate use can lead to unnecessary power consumption or screen longevity issues. To use the app most effectively:
- Avoid using the “indefinitely” option unless absolutely necessary
- Create triggers linked to specific apps or networks to control usage with context
- Use display-off settings when the screen is not in use
- Monitor battery levels closely if you’re using a MacBook without charging
The goal is to harness the tool’s power responsibly without wasting energy or compromising device health.
Who Should Use Amphetamine?
While anyone can benefit from temporary wake sessions, Amphetamine is especially beneficial for:
- Content creators and video editors
- Developers running long builds or simulations
- Remote workers participating in virtual calls or presentations
- Database or server administrators
- Researchers who run overnight analyses or data collection tools
If your workflow depends on maintaining system activity without interruptions, Amphetamine is an indispensable tool.
Conclusion
In an age where productivity and operational continuity are paramount, Amphetamine presents a reliable and effective mechanism to stay in control of your Mac’s sleep behavior. It combines usability with power-user flexibility, giving everyone from casual users to IT professionals a toolkit to ensure their Mac stays awake exactly when it’s needed.
With a trustworthy reputation, a host of sophisticated features, and zero cost of entry, Amphetamine is a must-have utility for responsible and efficient Mac usage.
