MacAFK – keeps your Mac active while simulating a locked screen

Summary: MacAFK is a native macOS tool that prevents sleep by simulating a locked screen through brightness dimming, allowing long-running tasks to continue uninterrupted under strict MDM policies. It features a smart mouse jiggler, adaptive brightness control, and power-saving optimization, supporting AI training, remote work, and corporate environments.

What it does

MacAFK uses hardware-level brightness control and mouse simulation to keep the Mac awake while appearing locked to MDM policies. It offers two versions: Pro with full system API access and Lite for App Store compliance.

Who it's for

It targets users running long automated workflows, such as LLM agents, developers, AI/ML training, and employees in corporate or remote work settings with screen lock restrictions.

Why it matters

MacAFK prevents interruptions caused by mandatory screen locks, enabling uninterrupted execution of long-running processes without violating security policies.
