Agents Never Sleep

Product Introduction

1. Definition: Agents Never Sleep is a lightweight, native macOS menu bar utility application designed to prevent system sleep and display dimming. Its core technical function is to override macOS power management settings, specifically to maintain system wakefulness even when the laptop lid is closed.
2. Core Value Proposition: It exists to solve the critical problem of interrupted long-running AI agent tasks, background jobs, and computational processes on Apple Silicon and Intel MacBooks. Its primary value is enabling unattended Mac operation with lid closed, eliminating the need for physical workarounds like keeping the laptop half-open or using external displays to trick the sensor.

Main Features

1. Menu Bar Control Center: The app resides exclusively in the macOS menu bar, providing a non-intrusive, always-accessible interface. From here, users can toggle between three distinct power states without opening a dedicated application window, ensuring minimal system resource usage and maximum convenience.
2. Three-Tier Sleep Prevention Slider: This is the core technical feature. It offers granular control over system power states: "Sleepy" (allows normal sleep but prevents display dimming), "Awake" (prevents system sleep but allows the display to turn off), and "Never sleeps" (the most aggressive setting that prevents both system sleep and display sleep, effective even with the lid closed).
3. Native & Privacy-Focused Execution: Built as a native macOS app, it integrates directly with Apple's frameworks (like IOKit and pmset commands) for reliable operation. It emphasizes a no data collection policy, meaning all settings and controls function entirely locally on the user's machine without phoning home or requiring an internet connection.

Problems Solved

1. Pain Point: The automatic sleep function in macOS, which cannot be fully disabled for lid-closed operation via standard System Preferences or built-in tools like caffeinate, forcibly halts ongoing computational tasks. This disrupts long-running AI agents, data processing scripts, large file transfers, renders, and software compilations.
2. Target Audience: Primary users include AI developers and researchers running local LLMs (e.g., Ollama, LM Studio), data scientists executing lengthy data pipelines, software engineers running extended tests or builds, and creative professionals rendering video or 3D graphics overnight.
3. Use Cases: Essential scenarios include: training a machine learning model locally overnight; running a continuous autonomous AI agent; downloading multi-terabyte datasets; performing a multi-hour video encode; or maintaining an active SSH or remote desktop connection to a MacBook used as a server.

Unique Advantages

1. Differentiation: Unlike the built-in caffeinate command-line tool (which terminates upon lid closure) or the "Prevent automatic sleeping" checkbox in Energy Saver settings (which doesn't apply when lid is closed), Agents Never Sleep provides a persistent, user-friendly solution that survives lid closure. Compared to other third-party apps like Amphetamine, it offers a simpler, more focused interface specifically tailored for the "keep awake with lid closed" use case.
2. Key Innovation: Its main innovation is the straightforward, reliable implementation of deep system-level sleep prevention that remains active during lid-closed operation on both Apple Silicon and Intel Macs, packaged in an extremely minimal, purchase-to-use model without subscriptions or complex configurations.

Frequently Asked Questions (FAQ)

1. How does Agents Never Sleep keep Mac awake with lid closed? It works by programmatically setting specific macOS power management (pmset) flags that tell the system to ignore sleep triggers from the lid-closed sensor and other idle timers, effectively forcing the system to stay in a wake state.
2. Is Agents Never Sleep better than using the caffeinate command in Terminal? For lid-closed operation, yes. The caffeinate command is a temporary process that is killed when the lid is closed. Agents Never Sleep applies a persistent setting that remains active until the user manually changes it or reboots, making it reliable for unattended, lid-closed sessions.
3. Does Agents Never Sleep work on Apple Silicon Macs (M1, M2, M3)? Yes, it is fully compatible with both Apple Silicon (M-series) and Intel-based MacBooks, leveraging macOS's standard power management APIs that are consistent across architectures.
4. Can I get a refund if Agents Never Sleep doesn't work on my Mac? The developer offers a 14-day money-back guarantee with no questions asked, providing a risk-free way to test the app's compatibility with your specific macOS version and hardware setup.
5. What's the difference between the "Awake" and "Never sleeps" settings? The "Awake" setting prevents the system from going to sleep but allows the display to turn off, saving some energy while keeping processes running. The "Never sleeps" setting prevents both system sleep and display sleep, ensuring the screen and system remain fully active, which is necessary for some specific tasks or remote access scenarios.
