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 Alerts
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.
Fan Speed Control

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 from 1 to 10 seconds. 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.

- macOS 14.0 (Sonoma) or later
