- Overview: used and free space, a row per tool, your biggest folders, and your last clean-ups with Undo
- System Junk: app caches, logs and Xcode build data
- Trash & Downloads: empty the Trash and sweep out old downloads
- Large Files: big files and things you haven't opened in ages
- Uninstaller: remove apps together with their support files, caches and preferences
- App Updates: updates for apps from the App Store and the web
Every item comes with a plain-language explanation and a Safe to Remove or Review First label.
Plus memory, CPU, battery and network at a glance, and a menu bar helper.
Safety first
- Everything is moved to the Trash first, so you can always restore it.
- Only items that are already in the Trash are deleted permanently, and Fussel asks before doing it.
- Fussel never touches system files, Apple apps, or the top-level folders in your home folder.
- Nothing is selected in Large Files or Trash & Downloads until you choose it.
Privacy
Fussel works on your Mac and keeps what it finds to itself. There are no accounts, no analytics and no tracking. It only goes online for these:
- Its own updates: it asks GitHub whether a new Fussel is out (at most once a day, can be turned off in Settings) and downloads it when you choose to update.
- Updates for your apps, only when you check: it asks the App Store about App Store apps, and each other app's own update feed about that app.
- The speed test, only when you start it: macOS's built-in
networkQuality tool measures your connection with Apple's servers.
- Send Feedback opens a GitHub form in your browser, filled in with Fussel's version, your macOS version and your Mac's chip. Nothing is sent until you submit it yourself.
Scan results, file lists and your clean-up history never leave your Mac.
Install
- Download Fussel-Installer.zip from the latest release. Your Mac unpacks it to Fussel-Installer.pkg; open that.
- Fussel isn't signed with an Apple Developer ID yet, so macOS blocks the installer at first:
open System Settings › Privacy & Security and click Open Anyway.
- Click through the installer. Fussel lands in Applications and appears in the menu bar.
- Optional but recommended: give Fussel Full Disk Access in
System Settings › Privacy & Security › Full Disk Access.
Prefer drag and drop? Use Fussel.dmg, then run
xattr -dr com.apple.quarantine /Applications/Fussel.app once before the first launch.
Check your download
Fussel isn't notarized by Apple yet, so here's another way to be sure a download is the real thing: every release file is built by GitHub Actions straight from this repository, and GitHub signs a record of exactly which commit and workflow produced it. With the GitHub CLI installed, run this in the folder with the download:
gh attestation verify Fussel-Installer.zip --repo Dshamil/fussel
It works the same for Fussel-Installer.pkg, Fussel.dmg and Fussel.zip. A ✓ means the file is byte for byte what this repository's workflow built; anything else means don't open it. (Releases from 1.1 on carry this record.)
Fussel lives in the menu bar: click the fluff to open or close it, right-click for more.
It starts with your Mac; turn that off in Settings.
Requires macOS 14 Sonoma or later. Runs natively on Apple Silicon and Intel.
Build it yourself
scripts/build.sh 1.0.0 # builds dist/Fussel.app
scripts/package.sh 1.0.0 # builds dist/Fussel-Installer.pkg and dist/Fussel.dmg
Needs Xcode 15 or later (or the Swift toolchain that comes with it).
Every push to main is built by GitHub Actions. To publish a new release, bump the
number in VERSION (for example to 1.0.1) and push: a release v1.0.1 with the
installer, disk image and zip attached is created automatically. If release-notes/<version>.md
exists, it becomes the release text (a first line <!-- title: … --> sets the release title);
otherwise GitHub generates notes from the commits.

Who makes Fussel
