Everything you need to know about your Mac, nothing you don’t.
CPU & Per-Core Monitoring
Total CPU usage at a glance plus a per-core bar graph breakdown in the detail popover. See exactly which cores are working hard.
Memory & Disk Usage
Used vs. total RAM with progress bars and sparkline history. Disk capacity shown the same way—know when you’re running low before it’s a problem.
Network Throughput
Upload and download bytes per second with separate sparkline graphs for each direction. Spot unexpected traffic or verify your downloads at a glance.
Temperature Monitoring
CPU and GPU temperatures via SMC, plus a full list of every detected thermal sensor, color-coded by heat, with history graphs to spot trends.
Fan Speed Control
Monitor per-fan RPM in real time, or take manual control with the optional helper — including on Apple Silicon. Custom speeds persist until you switch back to automatic.
8 Theme Presets
Colorful, Mono, Mono Dark, Mono Light, Pastel, Neon, Ocean, Midnight—pick a preset or customize every sensor color individually. Light, dark, and system appearance with automatic switching.
Battery & Power
Charge, health, cycle count, watts in and out, time remaining, and Low Power Mode detection — the full picture of your battery, not just a percentage.
Per-Process Breakdowns
Top-5 lists show which apps are eating CPU, memory, disk I/O, network, and energy — with smart naming that unmasks Electron and CLI apps.
Smart Threshold Alerts
Notifications for high CPU, memory, or temperatures and low disk or battery. Hysteresis means one alert on crossing — not a flood.
Designed to look as good as the data it shows.

Menu Bar Integration
Your menu bar, your way.
MHN Vitals adapts to how you work. Show sparkline graphs only for a minimal look, text values for precision, or both for the complete picture.
Pin individual sensors to the menu bar as persistent items with their own display styles. Toggle any monitor on or off—only see what matters to you.
Update intervals of 1, 2, 5, or 10 seconds—with adaptive sampling that skips heavy checks when no popover is open. Graph widths from 20 to 80 pixels. Heights from 12 to 24 pixels. It’s your menu bar.
- Graph Only Mode — compact sparklines with no text: maximum data, minimum space.
- Text Only Mode — numeric values for precise readings at a glance.
- Graph & Text Mode — the full picture: sparkline history with live numeric readouts.
- Persistent Menu Bar Items — pin any sensor directly to the menu bar with independent styling.
- Dark, Light & System Appearance — follows your macOS appearance preference automatically.
- Custom Sensor Order — reorder vitals to set both the popover sections and menu-bar layout.
- Split or Combined Network — one item or separate ↓/↑ readouts, each with its own graph.
