Mac High CPU Usage? Find What’s Causing It — Then Fix It

If your Mac feels slow, warm, or the fans start spinning loudly — and Activity Monitor shows high CPU usage — this video walks you through how to diagnose it correctly and fix it safely.

High CPU on a Mac isn’t automatically a problem. What matters is which process is responsible, how long it stays elevated, and whether it stabilizes under a light workload.

In this video, you’ll learn:
• How to read CPU usage properly in Activity Monitor
• What 100% CPU actually means on multi-core Macs
• How to identify which process is causing sustained load
• The correct fix order (quit → reopen → restart → update)
• How Login Items and background agents affect CPU
• Why browser tabs and extensions are common causes
• When high CPU is normal — and when it deserves deeper investigation

This is controlled troubleshooting — not cleaner apps, not aggressive tweaks, and not panic resets.

Applies to Apple Silicon and Intel Macs running modern versions of macOS.
