Mac

Real-time Mac & external SSD health, speed, and diagnostics - CPU, RAM, battery, thermal, and drive I/O at a glance. No data collected, ever. StatsCalm turns your Mac into an open book. It's a native, sandboxed system monitor built for people who plug in external SSDs and actually want to know what's happening inside them - and inside their Mac. WHY STATSCALM: Most system monitors show you a CPU percentage and call it a day. StatsCalm goes deeper, especially for external storage: bridge controller identification, live link speed, real-time throughput, and an honest health read that never invents a number it can't verify. SYSTEM AT A GLANCE - CPU: global load, User/System/Idle ticks, P-core vs E-core breakdown on Apple Silicon, per-core matrix, and a rolling history chart. - Memory: App, Wired, Compressed, Cached, and Free memory, plus memory pressure and swap usage. - Battery & Power: health percentage, charge cycle count, amperage, voltage, and pack temperature (MacBooks); AC status on desktop Macs. - Thermal: real-time system thermal state and discovered hardware temperature sensors. - Network: live throughput per interface, signal strength, channel, band, and PHY mode. - GPU: utilization and activity via IOAccelerator. EXTERNAL SSD CENTER - Automatic hot-plug detection the moment you connect a drive. - Bridge controller identification - Realtek, ASMedia, JMicron, and Intel Thunderbolt controllers. - Bus and link speed detection: Thunderbolt, USB4, and USB 3.x generations. - Real-time read/write throughput, IOPS, and latency, with 1m/5m/15m/1h timeline windows. - A real, user-initiated speed benchmark - measured sequential read/write performance, never a placeholder number. HONEST BY DESIGN StatsCalm reports drive health only when the data is real and verifiable through the properties macOS publishes. When a USB bridge blocks deeper diagnostics, StatsCalm tells you that plainly instead of guessing. What you see is always a real, measured value. PRIVACY FIRST StatsCalm runs fully sandboxed using only public macOS frameworks. It collects no data, tracks nothing, and needs no account. Your drive's telemetry stays on your Mac. Built for people who care about their hardware - creative professionals working off external drives, developers, and anyone who wants a clear, trustworthy read on their Mac's health.
