Keeping a Mac cool while AI agents do the work.

Why your Mac overheats when AI coding agents run
AI coding agents like Claude Code, Codex CLI and Cursor spawn builds, tests and dev servers that max out your CPU. Here is why a MacBook gets hot, how to find the culprit, and how to cool it.
How to check your Mac's temperature on Apple Silicon
macOS has no built-in temperature display. Here are the ways to check CPU temperature and thermal pressure on M1 to M5 Macs, from Terminal commands to apps.
How to cool down a Mac without stopping your work
Run heavy processes on your Mac's efficiency cores to cut heat and fan noise while builds, renders and AI agents keep running. Terminal method and one-click app.
WhoIsCooking vs Activity Monitor, iStat Menus and Stats
Compare WhoIsCooking with Activity Monitor, iStat Menus and Stats for Mac temperature and CPU monitoring when running AI coding agents. What each does best.
Codex turning your MacBook into a furnace: how to fix it
Codex CLI runs builds, tests and scripts that keep every core busy and heat up M1 to M5 MacBooks. Find which Codex session is the cause and cool the Mac without stopping it.
Cursor overheating your MacBook: causes and fixes
Cursor can make a MacBook Air or Pro hot through indexing, extensions, language servers and agent runs. How to find the cause and cool the Mac while you keep working.
MacBook hot but the fan is not spinning: why
Your M-series MacBook Pro feels hot but the fan stays quiet. Why Apple Silicon fan curves wait so long, what is normal, and how to cool it earlier.
Running parallel AI agents on a Mac without overheating
Several Claude Code, Codex or Cursor agents at once can overload a MacBook until it throttles, freezes or shuts down. How to cap the load and keep every agent running.
How to avoid MacBook Air throttling on long tasks
The fanless MacBook Air slows down under sustained load. How thermal throttling works, how to check it, and how to keep long builds, renders and AI agent runs faster for longer.
