CoreGuardRecorded incidents, scrubbable minute by minute.
The home page recorder replays three real-shaped Mac incidents. Here each one gets its own page you can link and cite — the numbers, the fans, and the plain-English explanation moving together. One is a real danger, one is heavy but harmless, and one is a healthy Mac that only looks scary — because the whole point is that you can't tell which is which from the noise alone. Every value is a recorded, hand-authored example — CoreGuard observes and explains, never a verdict.

Replay the incident → healthy — only looks scarythe export that only looks scary
A long Final Cut Pro export drives the CPU to ~700%, the die to 96°C, and the fans to a full 6,200 RPM. This is a recorded replay of a completely healthy Mac doing exactly what it's built to do — and how to tell that apart from trouble.
Replay the incident → dangerous — and silentthe silent SSD write storm
No heat. No fan noise. Nothing sounds wrong — and a runaway sync helper is quietly writing hundreds of gigabytes to your SSD, spending endurance you can't see. This is the incident type that hides from your senses.
