CPU, RAM, disk, network —
always visible
Live system stats in your menu bar. See CPU usage, memory pressure, disk capacity, network speeds, and battery health without opening Activity Monitor. Apple Silicon optimized.
Activity Monitor is buried three clicks deep
When your Mac feels slow, you open Spotlight, type "Activity Monitor", wait for it to load, and navigate to the right tab. By then, the spike might be over. Developers need system stats accessible in one click — not a full app launch. Most install iStat Menus ($14.99), adding another menu bar icon.
System awareness without the overhead
CPU Usage & Temperature
Real-time CPU utilization with user, system, and idle breakdown. See which cores are active and how hard your Mac is working.
Memory Monitoring
App memory, wired, compressed, cached, and free. Understand memory pressure at a glance without opening Activity Monitor.
Disk Capacity
Per-drive usage percentage and available space. Spot a filling disk before it causes build failures or crashes.
Network Speeds
Live upload and download speeds. Know instantly if a large transfer is running or if your connection has dropped.
Battery Health
Cycle count, capacity percentage, and health status. Pro adds configurable alerts when battery health drops below thresholds.
Top Processes (Pro)
See the top 5 CPU-consuming processes with PID, name, and usage percentage. Identify resource hogs without opening Activity Monitor.

Battery health tracking for long work sessions away from power. Know your cycle count and when to start planning a battery replacement.
Mac Power Users
Quick glance at system health without opening a separate app. Integrated with 6 other tools you already use from your menu bar.
Frequently asked questions
Is System Info free?
Core monitoring is free: CPU, RAM, disk, network stats, and hardware info. Pro unlocks battery health alerts and top 5 processes view. Pro costs $20 for 6 months.
How is this different from Activity Monitor?
Activity Monitor is a full window app you have to open and navigate. FavTray's System Info lives in your menu bar — one click to see CPU, RAM, disk, and network stats without leaving your current workspace.
Does it work on Apple Silicon?
Yes. System Info is Apple Silicon aware and shows efficiency vs performance core counts. It runs natively on M1, M2, M3, and M4 Macs.
Does monitoring affect performance?
No. System Info only collects stats while the popover is open. When you close it, monitoring stops completely. Zero background CPU usage.
How does it compare to iStat Menus?
iStat Menus is a dedicated system monitor ($14.99) with deeper metrics and its own menu bar icon. FavTray includes system monitoring plus 6 other tools in one icon for $20/6 months. If you only need system stats, iStat is more detailed. If you want system stats plus eye rest, AI tracking, and more, FavTray is the all-in-one option.
