What Does MoniThor Display in the Menu Bar?
MoniThor shows six system metrics as live sparkline graphs, color-coded values, and configurable widgets — all in a tiny strip of your menu bar.
CPU Monitoring
MoniThor tracks overall CPU usage, per-core utilization with P-Core and E-Core labels, user vs system split, load averages, thermal state, and system uptime.
Memory Monitoring
MoniThor displays used memory in GB, memory pressure and usage ring gauges, wired/compressed/cached/free breakdown, swap usage, and page in/out rates.
Network Monitoring
MoniThor shows real-time upload and download speeds, peak speeds since launch, Wi-Fi SSID, connection type, local IPv4/IPv6 addresses, and public IP with auto-refresh.
GPU Monitoring
MoniThor tracks GPU utilization percentage, VRAM usage, and GPU model name with Apple GPU branding for Apple Silicon Macs.
Battery Monitoring
MoniThor displays battery percentage, time remaining, battery health, charge cycles, power draw in watts, voltage, and charging state with color-coded indicators.
Disk Monitoring
MoniThor shows disk usage with available and purgeable space, real-time read/write speeds, top 5 storage categories with folder sizes, and auto-detected external volumes.
How It Works
How Does MoniThor Present System Data?
MoniThor provides three distinct views — menu bar widgets, a compact floating panel, and a full expanded dashboard — each designed for different monitoring needs.
01
Menu Bar Widgets
MoniThor places live sparkline graphs and color-coded values directly in your macOS menu bar. Each metric supports 4 display modes: text only, graph only, graph + text, or icon + text. A dark pill background with adjustable opacity keeps everything readable on any wallpaper.
02
Compact Panel (Click)
MoniThor opens a draggable floating panel when you click the menu bar icon. The panel shows 7 toggleable sections including per-core CPU bars with P-Core/E-Core labels, top 3 processes by CPU usage, and memory pressure gauges.
03
Expanded Dashboard (Option+Click)
MoniThor displays a full resizable overlay with 6 metric cards, a processes section, 8 accent color themes, animated glow graphs, and a session summary showing peak CPU/RAM/GPU and total network transfer since launch.
Guides
What Can You Monitor on a Mac?
MoniThor covers every aspect of macOS system monitoring. These guides explain what each metric means and why it matters.
Activity Monitor on Mac: Complete Guide
Activity Monitor shows running processes and resource usage on macOS. MoniThor puts the same data in your menu bar without opening a separate window.
How to Check Battery Health on Mac
Battery health degrades over charge cycles. MoniThor displays battery percentage, health, cycle count, power draw, and time remaining in the menu bar.
How to Check RAM Usage on Mac
RAM pressure determines whether your Mac needs more memory. MoniThor shows used memory, pressure gauges, and page in/out rates at a glance.
How to Monitor CPU Usage on Mac
CPU usage spikes cause slowdowns and thermal throttling. MoniThor displays per-core bars, P-Core/E-Core split, and load averages in real time.
How to Check Disk Usage on Mac
Running low on disk space degrades macOS performance. MoniThor shows used/free space, purgeable storage, read/write speeds, and external volumes.
Best Mac Menu Bar Apps for Monitoring
The macOS menu bar is the ideal location for system metrics. MoniThor is the only app that combines sparkline graphs with color-coded values.
FAQ
Frequently Asked Questions
What macOS versions does MoniThor support?
MoniThor supports macOS 13 (Ventura) and later, including macOS 14 Sonoma, macOS 15 Sequoia, and macOS 26 Tahoe. It runs natively on both Apple Silicon and Intel Macs.
What is the difference between the App Store and Direct version?
The App Store version ($4.99) is fully sandboxed and requires zero special permissions. The Direct version ($7.99) includes a privileged SMC helper for hardware sensor data like CPU temperature, GPU temperature, fan speeds, and power draw in watts.
Is MoniThor a subscription?
MoniThor is a one-time purchase with no subscription, no in-app purchases, and free updates within version 1. You pay once and own it forever.
How much memory does MoniThor use?
MoniThor is built with native Swift and SwiftUI — no Electron, no web views. It typically uses under 30 MB of RAM, making it one of the lightest system monitors available for macOS.
Can I customize which metrics appear in the menu bar?
MoniThor lets you toggle each metric independently, choose from 4 display modes per metric (text only, graph only, graph + text, icon + text), reorder metrics freely, and adjust sparkline width and background opacity.
