Is your Mac suddenly running hot while you code with AI — and you have no idea which tool is to blame? A new Mac app called WhoIsCooking answers exactly that question, showing which AI agent is heating your Apple Silicon Mac and offering a one-click way to cool it down.

The problem will be familiar to anyone who runs AI coding assistants. You start Claude Code, Codex or Cursor, the fans spin up, and Activity Monitor shows a wall of node and compiler processes with no temperature reading and no clear culprit. You know something is cooking your Mac, but you cannot tell what.
WhoIsCooking: See Which AI Agent Is Heating Your Mac
WhoIsCooking puts chip temperature in your Mac’s notch or menu bar, so the heat is visible at a glance. More usefully, it groups each AI agent session together with everything that session started into a single row. Instead of hunting through dozens of processes, you see one clear entry per agent — and you can tell at once which one is driving the temperature up.
That grouping is the app’s main trick. AI coding tools spawn helper processes, compilers and background jobs, which is why Activity Monitor feels unreadable during a heavy session. By rolling those children into their parent agent session, WhoIsCooking turns a messy process list into a simple answer: this agent, this much heat.
How to Cool Down Your Mac With WhoIsCooking
Once you spot the culprit, the fix is deliberately simple. WhoIsCooking includes a “Cool down my Mac” button that moves the busy work onto the efficiency cores of your Apple Silicon chip. Nothing is killed or frozen — the work keeps running, just a little slower, while the temperature drops.
The maker gives a concrete example from their own machine: on an M5 Mac, four processes running flat out went from about 83°C at full speed to about 48°C once cooled. That is a dramatic drop, and it shows why throttling to efficiency cores can be a better trade-off than letting a laptop roast through a long coding session.
There are honest limits to know before you buy. WhoIsCooking cannot cool GPU work or Apple’s own processes, and it requires Apple Silicon — M1 through M5 — running macOS 14 or later. It is also aimed squarely at people who actually run AI agents on their Mac; if you never touch Claude Code, Codex or Cursor, you will rarely see it do anything interesting.
WhoIsCooking Price and Availability
WhoIsCooking costs $5 as a one-time purchase, according to its Product Hunt listing. It is signed and notarized, and it needs no account to use. For developers who regularly leave AI agents running for hours, that is a small price for knowing — at a glance — which agent is turning their Mac into a space heater, and for having a single button to calm it down.
