MacTidy

See what fills your Mac. Clear only what's safe.

MacTidy maps every gigabyte on your disk, picks out the caches, build files and app leftovers you can safely remove, and moves them to the Trash so you can put anything back.

Coming soon How it works
  • $10.99 once, no subscription
  • Runs entirely on your Mac
  • macOS 14 Sonoma or later
Example scan Macintosh HD, 512 GB

An example scan of a 512 GB Mac: 72 GB of Xcode build files, caches, developer caches, app leftovers, Mail attachment copies and logs that are safe to remove, plus 89 GB of iPhone backups, simulators, Docker images and installers worth reviewing. Photos, documents, apps and macOS are shown but never touched.

Three steps, and you approve each one

  1. Scan

    MacTidy reads file sizes and locations across your disk. It doesn't open your files or upload anything, and a full scan takes seconds, not minutes.

  2. Review

    Every item shows its size, where it lives, and why it was flagged. Safe items are pre-selected. Anything that might hold your data waits for you to decide.

  3. Move to Trash

    Selected items go to the Trash, not straight to deletion. Changed your mind? Put them back from Finder. Empty the Trash when you're sure.

What it finds

Rules for each location are written and tested by hand, and they update without an app update when a tool changes where it keeps its files.

Disk map

A zoomable map of your whole disk, sized by the space files actually take up. Hard links and cloned files are counted once, so the totals match what macOS reports.

Developer leftovers

The biggest wins on a developer's Mac: build products, old simulators, device support files and package caches. MacTidy uses each tool's own cleanup command where one exists.

  • Xcode DerivedData
  • iOS DeviceSupport
  • Unavailable simulators
  • Swift Package caches
  • Homebrew
  • npm, pnpm, Yarn
  • pip
  • Docker build cache

App leftovers

Dragging an app to the Trash leaves its settings, caches and support files behind. MacTidy finds them by the app's bundle identifier, not its name, and checks no other installed app still uses a shared folder.

  • Application Support
  • Containers
  • Group Containers
  • Preferences
  • Saved Application State
  • Launch agents

Caches and logs

App caches, browser caches, Mail attachment copies and old logs. Caches that hold real data, such as offline music or downloaded maps, are left alone.

Large and old files

A sortable list of your biggest files and the ones you haven't opened in a year, with a Quick Look preview. Nothing here is ever pre-selected.

What MacTidy won't do

Plenty of cleaners sell fear. These are the lines MacTidy doesn't cross.

  • Claim to speed up your RAM

    macOS manages memory well on its own. Forcing it to drop cached data just makes apps slower to reopen.

  • Show scary warnings

    No red alerts, no "1,284 problems found". You see sizes and paths, and that's it.

  • Remove your photos, documents or mail

    They appear on the disk map so you know where your space went. MacTidy never selects them for removal.

  • Delete anything straight away

    Everything goes to the Trash first, so every cleanup can be undone until you empty it.

  • Watch what you do

    No analytics, no account. Your file list never leaves your Mac.

  • Charge you every year

    You pay once. Every 1.x update is included.

MacTidy is in development. The price above is the launch price.

Try before you pay

The free download scans your Mac and shows everything it would clean. A license unlocks cleaning and the uninstaller.

Who handles the payment

Checkout runs through Polar, which acts as the merchant of record: it processes the card, adds the right sales tax or VAT for your country, and sends your receipt and license key.

Moving to a new Mac

Deactivate MacTidy on the old Mac from its settings, or free up a slot from your customer portal, then activate on the new one.

Questions

Is it safe to use?

MacTidy only pre-selects items that apps rebuild on their own, such as caches and build files. Anything that could be your data is marked "Review first" and is never selected for you. Removed items go to the Trash, so you can put them back until you empty it.

Why does it ask for Full Disk Access?

macOS protects some folders, such as Mail and other apps' containers, from every app by default. Without Full Disk Access, MacTidy still works on everything it can read and tells you which folders it couldn't see. You can turn the permission off at any time in System Settings, under Privacy & Security.

Will it make my Mac faster?

It frees disk space. If your disk is nearly full, macOS slows down and updates fail, and freeing space fixes that. If you already have plenty of free space, a cleaner won't make your Mac noticeably faster, and MacTidy won't pretend otherwise.

Which Macs does it support?

Any Mac running macOS 14 Sonoma or later, with Apple silicon or Intel.

Does MacTidy collect any data?

No analytics and no file lists. The app contacts our servers only to activate your license and to check for updates. The privacy policy lists exactly what those requests contain.

Can I get a refund?

Yes. Ask within 14 days of purchase and you get your money back, no questions asked. See the refund policy.

Why isn't it on the Mac App Store?

Mac App Store apps run in a sandbox that blocks them from reading other apps' caches and leftovers, which is most of what a cleaner does. MacTidy is signed with an Apple Developer ID and notarized by Apple instead, so macOS checks it the same way.

Who makes MacTidy?

Zeus Olivar, an independent developer who has shipped six apps on Apple's platforms. Questions and bug reports go straight to him through the support page.
