The ultimate macOS power-management utility

Absolute control over your Mac’s sleep behavior — a premium menu-bar app that keeps your system awake until the job is done.

What it is

Precision temporal control

Running long data-processing scripts, holding remote SSH sessions, or rendering large files? KeepAlive ensures your Mac stays awake and focused — a high-performance menu-bar app that gives you absolute control over sleep behavior.

Built natively in Swift with a minimal footprint, it wraps complex system-level power commands in an ultra-premium, intuitive interface. Say goodbye to clunky terminal commands — hello to customizable timers and an interactive Status Orb.

Two modes

Every scenario, covered

Simple Mode

Idle prevention

Prevents display and system idle sleep via the native macOS caffeinate process. 100% safe, non-intrusive, and no administrator privileges — perfect for long videos or reading without interruptions.

Full Mode

Clamshell power

Modifies deep system-level sleep parameters (pmset) to override lid-sleep, so long-running scripts, downloads, and autonomous AI agents keep operating even with the lid closed. Requires admin privileges.
