MMilkmaid v0.1
Free · No login

A free Mac tool from The Ideas Shed

What the fuck is eating your Mac?

Milkmaid scans your Mac locally, shows you where the space went, and explains what deserves a look. She was built for Marcus—founder of The Ideas Shed—because his MacBook Air kept filling up while he built software.

What the real Milkmaid does

This website

The front door

Explains Milkmaid and gives you the Mac app. A website cannot inspect your filesystem—and this one does not pretend it can.

The local Mac app

The actual milkmaid

Scans names and sizes on your Mac, locally. Nothing is uploaded. v0.1 can explain and reveal items in Finder; it cannot delete or move them.

Free. Local. Rather pink.

Milkmaid is a free, no-login, early v0.1 Mac tool. It runs locally, scans read-only, never deletes files and does not upload your filesystem analysis.

Built and dogfooded by The Ideas Shed on Marcus’s MacBook Air while he was building software and repeatedly running out of space.

Before you download

  1. Early Mac releasev0.1 for Apple-silicon Macs running macOS 13 or later. It is Mac-focused and not a universal compatibility promise.
  2. Local and read-onlyFilesystem analysis stays on your Mac. Milkmaid cannot delete or move anything; protected folders may remain partial.
  3. Apple security warningThis build is not yet Apple-notarised. The Ideas Shed is arranging the appropriate Apple Developer setup and notarisation, so browsers or macOS may currently show security warnings.

If something is unsupported: “Bugger. I couldn’t inspect that properly, so I’ve left it completely alone.”
