JClean Download

Download JClean

Version 1.1.0 · released September 28, 2026 · for Mac (Apple Silicon and Intel), Windows and Linux.

Opening JClean the first time on a Mac

JClean isn't notarized by Apple yet, so macOS blocks it the first time. This is expected, and you only have to do it once. It takes about 30 seconds.

  1. Step 1

    Open the downloaded DMG and drag JClean into Applications.

  2. Step 2

    Open JClean. macOS says it can't verify the app. Click Done.

    Don't click "Move to Trash".

  3. Step 3

    Open System Settings → Privacy & Security, scroll down to "JClean" was blocked to protect your Mac, and click Open Anyway. Enter your password when asked.

  4. Step 4

    JClean opens. From now on it opens like any other app.

    Updates install from inside JClean (Settings → Updates) and don't need these steps again.

Why the warning? Apple charges developers to notarize apps, and JClean is a free project. The code is open on GitHub, and you can check the file you downloaded against the checksum below.

Installing on Windows

The installer isn't code-signed yet, so Windows SmartScreen may stop it the first time. This is expected, and you only see it when installing.

  1. Step 1

    Open JClean_windows_x64_setup.exe. If Windows says it protected your PC, click More info.

    Don't click "Don't run".

  2. Step 2

    Check the publisher line says Unknown publisher and the app is JClean, then click Run anyway.

  3. Step 3

    The installer puts JClean in your account only, so it doesn't ask for an administrator password. JClean opens when it's done.

    Updates install from inside JClean (Settings → Updates) and don't show this warning again.

"Smart App Control blocked an app that may be unsafe"?

Some new Windows 11 PCs have Smart App Control on, which blocks every app that isn't code-signed and has no Run anyway button. JClean's installer will be signed in a future version. Until then it can only be installed with Smart App Control off (Windows Security → App & browser control → Smart App Control). On most versions of Windows 11 it can't be turned back on without reinstalling Windows, so only do this if you're comfortable with that.

Installing on Linux

Pick one: the .deb for Ubuntu, Debian, Mint and Pop!_OS, or the AppImage for any other distribution. Both update themselves from Settings → Updates.

.deb (Ubuntu, Debian, Mint, Pop!_OS)

  1. Step 1

    Open your Downloads folder in Files, right-click an empty spot and choose Open in Terminal.

    Double-clicking the .deb may open App Center, which can't always install downloaded packages. The terminal always works.

  2. Step 2

    Install it with apt and enter your password. apt also installs anything JClean needs.

    sudo apt install ./JClean_linux_amd64.deb

  3. Step 3

    Open JClean from your apps. That's it.

AppImage (any distribution)

  1. Step 1

    Install FUSE 2, which AppImages need and newer systems leave out. Without it, nothing happens when you open the file. 

    # Ubuntu 24.04 and newer
sudo apt install libfuse2t64

# Ubuntu 22.04, Debian, Mint
sudo apt install libfuse2

# Fedora
sudo dnf install fuse-libs

  2. Step 2

    Allow it to run: right-click JClean_linux_x86_64.AppImage, choose Properties, and turn on Executable as Program.

    Or in a terminal: chmod +x JClean_linux_x86_64.AppImage

  3. Step 3

    Double-click it to open JClean. Keep the file somewhere permanent, like a folder called Applications in your home.

Tray icon on GNOME: it needs the AppIndicator extension. Ubuntu includes it; on Fedora, install AppIndicator and KStatusNotifierItem Support from Extension Manager.
