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.
