How to Fix Mac Overheating

First: is it actually overheating?

A warm MacBook is normal. A hot MacBook that throttles, has loud fans, or becomes uncomfortable to touch — that's overheating. The threshold is roughly 95°C for CPU temperature. Below that, your Mac is working as designed, even if the bottom feels hot. Apple's aluminum chassis is literally designed to conduct heat away from internal components, which means the case gets warm by design. But if your Mac is slow AND hot, that's a real problem.

The usual suspects

Nine times out of ten, overheating is caused by a process eating CPU. Open BreezeKit's Processes tab and sort by CPU usage. Common culprits: kernel_task (macOS's own thermal management — ironic), WindowServer (happens with external displays), mdworker (Spotlight indexing), and browser processes. If you see something consistently above 100% CPU, that's your heat source. Sometimes the fix is as simple as restarting the offending app.

Hardware fixes that actually work

Blow compressed air through the vents (especially on Intel MacBooks — they accumulate dust inside). Use a laptop stand or elevated surface — lying flat on a desk blocks the bottom vents on most MacBook models. Don't use your MacBook on a bed, couch, or blanket. If you use a closed-lid setup with an external display, your Mac has zero natural airflow — a stand that props it vertical helps enormously.

The BreezeKit approach

Use fan control proactively. Before starting CPU-heavy work, switch to Smart mode or manually bump fans to 4000+ RPM. Cooling the Mac before it gets hot prevents thermal throttling entirely. Monitor the Thermal section during heavy work — if you see CPU approaching 90°C, increase fan speed immediately. I run my fans at 3500 RPM baseline during development work. The noise is barely audible, and my CPU stays under 75°C even during builds.
