MacMonitor
Real-time Apple Silicon system monitor for your menu bar
Overview
What it is
MacMonitor is a free, open-source system monitor built specifically for Apple Silicon (M1–M4). It lives in your menu bar, updates every 2 seconds, and opens a full dark-mode dashboard showing CPU per-core usage, GPU, memory, battery health, power rails, network, disk I/O, and your top processes — all from the metal, no subscriptions. Install in one command: brew tap ryyansafar/macmonitor && brew install --cask macmonitor
Intent
I need it when
Track power consumption and thermal throttling to optimize Mac performance
MacMonitor shows real-time power draw across CPU, GPU, ANE, DRAM, and system rails, plus fan RPM and thermal state, enabling users to identify performance bottlenecks and thermal issues before they impact workflow
Get a quick system health overview without opening Activity Monitor
MacMonitor's menu bar indicator uses a color-coded dot (green/yellow/red) to show overall system load at a glance, and clicking opens a full dashboard with CPU, GPU, memory, network, disk, and process details in one view
Monitor system metrics on desktop or in Notification Centre without background processes
MacMonitor includes a native macOS widget (small, medium sizes) that displays CPU, GPU, memory bars and temperatures, refreshing every 5 seconds with zero background process overhead
Monitor real-time CPU, GPU, memory, and thermal performance on Apple Silicon Mac
MacMonitor displays live CPU usage (per-core and cluster breakdown), GPU frequency/temperature, memory utilization, and CPU die hotspot temperature directly in the menu bar with 2-second refresh intervals, using native Apple kernel sensors (SMC, IOReport) without third-party dependencies
Drop
Not a fit when
- User has a non-Apple Silicon Mac (Intel-based) — MacMonitor is designed exclusively for Apple Silicon Macs and requires native kernel sensor access specific to ARM architecture
- User runs macOS versions older than Ventura (13) — the product requires macOS 13 Ventura or later and does not support earlier OS versions
- User needs a notarized, App Store-distributed application — MacMonitor is not notarized and cannot be submitted to the Mac App Store due to sandbox restrictions required for kernel API access
- User requires commercial support or SLA guarantees — MacMonitor is community-maintained open-source software with no official support contracts or service level agreements
- User cannot grant admin/root privileges — MacMonitor requires one-time admin approval to install a privileged helper for IOReport access, which some enterprise environments may restrict
