ActiveStat is a calm system observer — delivering high-fidelity telemetry in a clean, minimal interface. Quiet when your Mac is efficient. Clear when it matters.

Key Features:

Smart Insight Engine
Real-time system interpretation — not just raw numbers. Monitor thermal state, energy impact, sustained load, and CPU with contextual summaries that make sense instantly.

CPU Activity
Deep visibility into processor performance. Track total usage, individual core load, cluster activity, system uptime, and idle capacity with precision.

Memory & Swap Clarity
Understand where your RAM goes. Clear breakdowns of App Memory, Wired, and Compressed memory, with macOS pressure level and live swap I/O when your Mac starts paging to SSD.

Disk Telemetry
Live read and write speeds across every connected volume — internal and external — so you can see how storage activity evolves throughout your workflow.

Intelligent Energy Impact
A real-time energy classification powered by CPU load, thermal state, and memory pressure. Includes battery health data and time-remaining estimates on MacBook models.

Smart Alerts
Get notified on sustained CPU or memory pressure, low storage, and low battery — each with a threshold you can dial in. Stay ahead of issues without watching a dashboard.

Minimalist, Respectful UI
A refined glass interface designed to stay out of the way. Smart Auto-Expand and configurable Insight Verbosity keep the experience calm by default, detailed when you need it.

Optimized for Apple Silicon
Designed for M-series Macs. View Efficiency and Performance core clusters independently to understand how your chip distributes work.
