brew install --cask tuguidragos/tap/peel
Dragging an app to the Trash leaves pieces of it behind. Caches, settings, containers, launch agents, and support files, scattered across your Library, sometimes gigabytes of them. Peel finds what an app left, tells you why each file belongs to it and how sure it is, and moves what you choose to the Trash.
Get the highlights.
Almost everything can come back.
What Peel removes goes to the Trash, and History puts it back where it was. The few exceptions are named before you confirm.
In your language.
English and 17 other languages, in the words macOS itself uses.
Mac settings, in plain sight.
Settings macOS already has, many of them out of sight, each one explained.
Terminal, set up.
29 dark themes, a prompt, and switches for settings zsh, Git, and ssh already have.
No analytics. No account.
On its own, Peel goes online only to check your apps, and itself, for updates, and you can turn that off.
Apple silicon and Intel.
On every Mac that runs macOS Tahoe 26 or later, and every release is tested by hand before it ships.
Uninstall
Every leftover.
With a reason.
Peel searches the places apps keep files, and gives each one the reason it matched, such as the app’s bundle identifier, its signing team, or a Homebrew cask that names it.
-
Selected with care.
What Peel finds to be the app’s alone is selected for you, unless it has a reason to hold it back, such as something inside that may exist nowhere else. A file another app also uses is shown, but never selected for you.
-
Review Before Removing.
What Peel is less sure of, what another app also uses, and what Peel holds back wait there, and the note beside each file says why.
-
Several ways in.
Choose an app in the list, drop one on Peel’s Dock icon, or Control-click it in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.
-
Reset instead of remove.
Make an app forget its settings without uninstalling it. Peel copies them first, so you can put them back.
-
Updates for your apps.
Peel checks each app through its own update feed, the App Store for apps bought there, or Homebrew for apps it installed, and shows what’s new.
-
Watch the Trash.
Turn it on and allow its notifications. While Peel is open or in the menu bar and has Full Disk Access, an app you drag to the Trash yourself brings a notification that takes you to what it left behind.
Space
See what fills your disk.
How full your disk is, then the places that take the most room, each with a note on what it is. What you select stays selected while you look at the other pages, iCloud Drive aside, and Move to Trash moves it all at once, as one entry in History.
-
Orphaned Files
Files left behind by apps you already removed, which no app on this Mac claims.
-
Build Artifacts
What builds left in your projects, like
node_modules,DerivedData, ortarget, each only when its tool’s own file proves it. -
Duplicates
Files and whole folders with identical contents, compared with SHA-256. One copy is always kept.
-
Installers and Backups
App installers in Downloads, Desktop, Documents, Public, and Shared, macOS installers, device firmware, unfinished downloads, updates waiting to install, and what your iPhone and iPad backups hold. A disk image may be one you made, so nothing is selected for you.
-
iCloud Drive
Files already safe in iCloud that are also downloaded to this Mac. Remove Downloads takes away only the copy on this Mac.
-
File Search
Large or old files, found through Spotlight by name, kind, or size, and narrowed by age.
Developer
Caches, folder by folder.
What each of your developer tools keeps. What you may want again is listed but never selected for you, and toolchains or anything holding an account are never listed.

Tweaks
Small tricks.
A little easier every day.
40 settings macOS already has, many of them out of sight. Each tweak says what it changes, and turning it off puts back what was there before, or leaves it to macOS.

- Typing

Terminal
Set up Terminal.
Choose a theme and a prompt, and turn on settings zsh, Git, and ssh already have, each with its own switch. There are 29 dark themes, all built on Apple’s own Clear Dark.
Hadal
-
Themes
Choose one, and Terminal opens with it in every new window. Put Back gives Terminal the profile it had before.
-
Terminal
Leave out the “Last login” line, keep Terminal from reopening its windows, and in the Peel theme you use, make Option the Meta key and silence the bell.
-
Shell
Use Peel’s prompt or keep the one you have, and turn on what zsh already has, like history shared between windows.
-
Git
Turn on what Git already has, like rebase when pulling. Turn All Off puts back what Peel changed, and returns the rest to Git’s defaults.
-
SSH
Keep connections alive, and more of what ssh already has, each with a switch.
-
Tools
Command-line tools worth having, with the Homebrew command and what each needs after, such as the lines to add to
~/.zshrc.
A cleaner should never cost you something you wanted.
Nothing of yours is deleted without asking first. What Peel removes goes to the Trash, and History puts it back where it was.
-
The Trash, never deletion.
Only four things Peel starts can’t be put back that way: Homebrew’s own uninstall and cleanups, resetting an app’s privacy permissions, and Force Quit for an app that won’t quit. Peel says so before you confirm them, and warns before it moves an app that deletes its own settings when it goes, like Mullvad VPN.
-
Protected places stay protected.
iCloud Drive, keychains, your SSH and signing keys, the keys of crypto wallets, Mail, Messages, Safari, Contacts, Calendars, Notes, photo and music libraries, iPhone and iPad backups, and the Desktop, Documents, and Downloads folders themselves. No selection can override it.
-
Crypto wallets are never selected for you.
A browser profile holding a wallet extension Peel knows, or Brave’s own wallet, stays where it is, so uninstalling a browser never takes the wallet with it.
-
Checked again at the last moment.
Peel looks at each item once more right before it moves, so something swapped in the meantime stays where it is.
-
Your exclusions, everywhere.
Nothing you exclude is ever moved, and neither is a folder holding something you excluded. An excluded app still appears in Applications but gets no removal plan, and the folders named with its identifier, such as its caches, leave every page. To keep its other files, exclude them too.
-
Every decision explained.
When Peel holds a file back, the row says why. A folder it couldn’t measure or read is shown as unknown, never as empty.
Privacy
No analytics.
No account.
On its own, Peel goes online only to check your apps, and itself, for updates, and you can turn that off. Each check asks about one app alone, through its own update feed or the App Store, and doesn’t send its version, your macOS, or your languages; the App Store is told only your Mac’s region. Release notes are asked for in your language when the feed offers them in several.
Settings > Privacy shows what Peel sends, and every address it or Homebrew may contact.
The peel command
Much of Peel,
from Terminal.
Every command that moves your files asks first, and takes --dry-run to only show the plan. What it moves goes through the same checks as in the app, into the same History.
-
peel leftovers Obsidian - # the files an app leaves behind, and why
-
peel uninstall Obsidian --dry-run - # only show the plan
-
peel orphans - # files of apps no longer installed
-
peel duplicates ~/Downloads - # identical files and folders
-
peel history - # what Peel moved to the Trash
-
peel restore <id> - # put one of them back

Questions.
What is Peel?
Peel is a free, open source app for macOS that uninstalls apps together with the files they leave behind, and tells you why each file belongs to the app. It also frees disk space, looks after Homebrew and what runs in the background, changes settings macOS already has, many of them out of sight, and sets up Terminal.
How do I completely uninstall an app on a Mac?
Open Peel, choose the app under Applications, look over what Peel found, and click Move to Trash. The app and its leftovers go to the Trash together, and History can put them back. You can also Control-click the app in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.
Can Peel delete something I need?
Peel moves files to the Trash instead of deleting them, and History can put them back while they’re still there. What can’t be undone, such as Homebrew’s own uninstall, Peel names before you confirm it. It never selects a file another app uses, and refuses to move iCloud Drive, your keychains, Mail, Messages, and photo libraries.
Why does Peel show a smaller size than Finder?
Peel shows what moving an item to the Trash would free, and Finder shows the space it takes. The two differ when files share their space: a copy Finder makes on an APFS disk shares its blocks with the original until one of them changes, and a file can have a second name somewhere else, which keeps it. Peel counts only what would really go.
Why does Peel ask for Full Disk Access?
macOS keeps other apps’ data, and the Trash, out of sight of any app without it. Peel works without it, but can’t see everything an app leaves behind.
Does Peel collect any data?
No. Peel has no analytics and no account. On its own, it goes online only to check your apps, and itself, for updates, which you can turn off. Homebrew goes online when you ask it to do something.
Is Peel really free?
Yes. Peel is free and open source under the GNU General Public License, version 3 or later, with no paid edition, no ads, and no account.
Can I install Peel with Homebrew?
Yes. Run brew install --cask tuguidragos/tap/peel in Terminal. It installs the same release as the download on this page.
Does Peel work on Intel Macs and older versions of macOS?
Peel runs on macOS Tahoe 26 or later, on any Mac that runs it: every Mac with Apple silicon, and the few Intel Macs from 2019 and 2020 that Apple lists for macOS 26. It doesn’t run on earlier versions of macOS: each version moves where apps keep their files, so every release is tested by hand before it ships, on macOS 26 and every version since.
How do I uninstall Peel itself?
In Settings > General, choose Remove Peel. Peel removes its helper and its login item, moves itself, the files that are certainly its own, and its folder in Application Support to the Trash, all but the Terminal settings zsh and ssh read, and clears its settings. What you set in Tweaks and on the Terminal page stays as it is. If you installed it with Homebrew, Settings shows the Homebrew command to run instead.
