What's monitored

Every metric that matters.

🔲
CPU
Per-poll usage percentage and die temperature via SMC. Color-coded from healthy green through amber to red-orange as load climbs.
GPU
GPU utilization sourced directly from IOKit's accelerator interface. Works on both Apple Silicon and Intel Macs.
Memory
Used vs total RAM in GB with memory pressure tracking. Matches exactly what Activity Monitor reports — no guessing.
🌡
Thermals & Fans
Live fan RPM, load bars, and OS thermal state. Apple Silicon fans idle at 0 RPM — that's shown correctly too.
Disk I/O & Storage
Read and write throughput from IOKit block storage drivers, plus used/total disk space matching Finder's numbers exactly.
↑↓
Network
Upload and download speed across all active interfaces. Decimal MB/s to match macOS conventions. No averages, no smoothing.

Expanded panel
