A lightweight, native macOS menu bar app that monitors CPU, memory, disk, network, temperature, and fan speed in real time. Beautiful sparkline graphs, color-coded sensors, and detailed popovers—all without leaving your workflow.
CPU. Memory. Disk. Network. Temperature. Fans. All in your menu bar with real-time sparkline graphs and zero dock clutter.
MHN Vitals lives in your menu bar and starts monitoring the moment you launch it. No configuration required—just open and go.
Download and drop MHN Vitals into your Applications folder. That’s it.
Opens quietly in your menu bar—no dock icon, no windows in the way
Click the icon for a compact popover with all sensors, sparklines, and live data
Pick your theme, toggle sensors, pin favorites to the menu bar permanently
Total CPU usage at a glance plus a per-core bar graph breakdown in the detail popover. See exactly which cores are working hard.
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.
Upload and download bytes per second with separate sparkline graphs for each direction. Spot unexpected traffic or verify your downloads at a glance.
CPU and GPU temperatures via SMC with color-coded warnings—green under 75°C, yellow at 75°C, red at 90°C. Know when your Mac is running hot.
Monitor fan RPM in real time, or take manual control with the optional privileged helper. Set custom fan speeds when you need maximum cooling.
Colorful, Mono, Pastel, Neon, Ocean, Midnight—pick a preset or customize every sensor color individually. Adapts to dark and light mode.
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 from 1 to 10 seconds. Graph widths from 20 to 80 pixels. Heights from 12 to 24 pixels. It’s your menu bar.
