System Monitor
A lightweight system monitor that lives in your menubar. Real-time CPU, memory, network, and thermal monitoring — everything you need to know about your Mac, always at a glance.
24-hr free trial · No credit card required
Watch every core individually. Beacon shows you exactly how your processor is being used — not just the average, but each core's contribution, split by user and system time.
Memory pressure tells you more than just usage. Beacon shows you the full picture — how much is actively used by apps, how much is locked in by the system, and how much has been compressed to make room.
Know instantly whether your Mac is downloading, uploading, or idle. Colour-coded sparklines give you a 60-second history of your network activity at a glance.
Know exactly how hot your Mac is running. Beacon reads every temperature sensor in your system and colour-codes them against defined thermal zones — cool, warm, hot, and critical.
Beyond the percentage in your menubar. Beacon shows you the full health story — how many cycles your battery has gone through, its current maximum capacity versus when it was new, and whether it needs attention.
See exactly where your storage goes. Beacon shows used, purgeable, and free space for every mounted volume — including a breakdown of what macOS can reclaim if you need room.
Pay once, yours forever.
