5 things are holding this Mac back.

  • Chrome is using 9.8 GB of memory

    Apps are competing for RAM and macOS has started swapping.

  • Xcode kept the CPU busy for 10 minutes

    84% on average. Everything else is waiting for it.

  • Macintosh HD is 84% full

    macOS needs free space for swap and updates.

  • 3 dev servers idle since yesterday

    They hold 1.4 GB and ports 3000, 4321 and 8000.

  • 2 leftover startup items

    They launch programs from apps you already deleted.

Everything, one click away.

Click the heart in the menu bar. Score, CPU, memory, disk, network, GPU, battery, temperature and power, the apps using the most, and your dev servers. Right-click an app to quit it.

A closer look.

One score, and what to fix.

The Health page scores your Mac from 0 to 100 and lists every problem that costs points: memory pressure, swap, a full disk, idle dev servers, leftover startup items, a battery that needs service. Each one comes with its fix.

Space back, safely.

Finds what a developer's Mac fills up with: Xcode builds, old node_modules, package caches, Docker leftovers, big forgotten downloads. It says what each one is and whether it is safe, and moves it to the Trash so you can change your mind.

MacHealth Free Up Space page listing caches and old files by category with their sizes.

What your AI tools use.

Tokens per day and per model from Claude Code and Codex, what they would cost at API prices, your top projects, and how close you are to your Codex plan limit. Read from local logs only.

MacHealth AI Usage page with tokens per day, cost at API prices and usage per model.

Memory, by app.

See how much memory each app really uses, with all its helper processes added in, and how your RAM splits into app memory, wired, compressed and cache. Swap and memory pressure are right at the top.

MacHealth Memory page: memory in use, free and swap, memory by type, a live chart and apps sorted by memory.

Every core, every app.

Live load on each performance and efficiency core, and which app is keeping the CPU busy. Switch the chart to 12 hours, 24 hours, 7 or 30 days to see what happened while you were away.

MacHealth CPU page: CPU now, user and system load, per-core bars, a live chart and apps sorted by CPU.

Your ports, by project.

Every server listening on a port, grouped by the repo it runs in, with its memory and how long it has been idle. Open it in the browser or stop it. MacHealth always asks first.

MacHealth Dev Servers page listing local servers by project with their ports and memory.

Battery and energy.

Battery health against its original capacity, cycle count, temperature, and how many watts the whole Mac is drawing, with the energy each app uses.

MacHealth Battery page: charge, health, temperature, power draw, a live chart and apps sorted by energy.

Temperatures and fans.

CPU temperature, every sensor on the chip, fan speeds, and the battery level of your AirPods, mouse and keyboard.

Alerts when an app misbehaves
A notification when an app pins a CPU core, keeps growing in memory, or hammers the disk or network.

Every Monday morning: your average score, the heaviest apps of the week and the space you cleaned up.

Exact figures for system processes

Ask Claude Code why your Mac is slow. MacHealth answers with the score, the causes and the fixes, and can quit an app or stop a dev server once you say yes.
