Mac Cleaner Download

Built for developers

Know your Mac's health.
All in one app.

Xcode, simulators, Android SDKs, node_modules, Docker, five Node versions and a Postgres you forgot about. Disk Cleaner finds what's eating your disk, what's out of date and what's exposed, then helps you fix it — with a preview before anything changes.

One app instead of five

Cleaner, version checker and security audit in one window.

Clean

Get the disk back

Build products, simulator runtimes, SDKs, package caches, Docker layers, large files and duplicates.

 Toolchains

Know what's out of date

Every Node, Python, Ruby, JDK and Go on your PATH, graded against official end-of-life dates.

 Security

Spot what shouldn't be there

System protections, launch agents and daemons, unsigned or orphaned background code.

 Network

See what's listening

Firewall, sharing services, proxies — and dev servers or databases open to the whole Wi‑Fi.

Clean

Tens of gigabytes that rebuild themselves.

Every item says what it is, how big it is and what happens after it's gone. Try it on a typical iOS and React Native disk.

A typical developer disk

— free of 494 GB

Point at a tile to see what it is and whether it comes back on its own.

  • Rebuilds itself
  • Probably safe
  • Your call
  • Your files — never selected for you
Xcode & simulators
DerivedData, previews, device symbols, archives, runtimes you no longer target and devices whose runtime is gone.~/Library/Developer/Xcode/DerivedData
Packages & toolchains
npm, Yarn, Bun, pnpm, CocoaPods, Gradle, SwiftPM, Cargo, Maven, Go, pip, uv, Homebrew, Metro and Expo.~/.npm, ~/.gradle/caches, ~/.cargo/registry
IDEs & SDKs
Android Studio and the Android SDK — NDK versions, system images, build tools — plus JetBrains, VS Code, Cursor and Zed.
Docker
Build cache, stopped containers and unused images through the Docker CLI. Volumes are never touched.
Your files
Large files, byte-identical duplicates and a map of any folder — never preselected.
Applications
Every app with its size and when you last opened it, plus app caches, logs and updater leftovers.

Toolchains

Five Node versions. One of them reached end of life.

Disk Cleaner finds the runtimes you installed through Homebrew, nvm, fnm, Volta, pyenv, rbenv, asdf and rustup, and grades each one against its official release schedule.

  • Rates each one update now, soon or when convenient — and says why.
  • Gives you the exact command for your install method. You run it; nothing changes behind your back.
  • Works offline until you press Check Online. Your versions are never sent.

Rust rustup1.82.0 Up to date

Security & network

The audit you'd run by hand — in one click.

Years of SDKs, installers and helper tools leave background code behind. Disk Cleaner reads what macOS starts at login and what's listening on your network, and explains each finding in plain words.

  • System protections — SIP, Gatekeeper, FileVault, device management.
  • Launch agents & daemons — unsigned code, programs that no longer exist, anything that runs from a folder anyone can write to.
  • Network — firewall and stealth mode, Screen Sharing, SMB, AirPlay, proxies, and Postgres, Redis, MongoDB or a dev server exposed beyond localhost.
  • A launch daemon runs from a folder anyone can write to Any app could replace that file and have it run as root.
    Critical
  • Firewall is off Incoming connections reach every service that listens.
    Warning
  • PostgreSQL on port 5432 is open to your network Bind it to 127.0.0.1 unless others need it.
    Warning
  • Two launch agents point to programs that no longer exist Leftovers from uninstalled updaters. Safe to remove.
    Info
  • SIP, Gatekeeper and FileVault are on
    OK

Knows your stack.

Built not to break things

Confident, because it's careful.
