actually doing.

Activity Monitor shows you the numbers.
MacStats explains what they mean.
When kernel_task spikes to 200% or mds_stores eats your CPU, Activity Monitor gives you a red number. MacStats gives you an answer.
What does kernel_task 189% mean? Why is mds_stores running?
kernel_task is using 189% CPU — this is macOS acting as a thermal governor. It intentionally consumes CPU to slow down other processes and protect your hardware from overheating. Uptime is 01-05:55:12.
