Changelog

1. Version 1.1.0

   September 28, 2026

   What's new

   JClean now runs on Windows and Linux, with the same safety rules as on the Mac.

   Windows 10 and 11

   • Finds temporary files, crash dumps, the Recycle Bin, browser and app caches, and every developer cache the Mac version knows about.
   • Clears Windows Update downloads, the Delivery Optimization cache and old versions of Windows components, and removes a previous Windows installation (Windows.old) with Windows' own Disk Cleanup. These ask for administrator approval once per clean.
   • Never downloads OneDrive files that are only in the cloud, and never follows links out of the folders it cleans.
   • Mica behind the sidebar on Windows 11.

   Linux

   • Finds ~/.cache, the Trash, thumbnails, Flatpak and Snap app caches, and the developer caches.
   • Clears the APT or DNF package cache, trims the system journal to the last two weeks, removes old Snap versions, and finds data left behind by Flatpak apps you've uninstalled. System items ask for your password once per clean.

   Everywhere

   • Buttons have stronger contrast, so their text is easier to read.

   Download

   • Mac: JClean_macos_universal.dmg. Apple Silicon and Intel, macOS 12 or later.
   • Windows: JClean_windows_x64_setup.exe. Windows 10 or 11, 64-bit. Installs for your account only, no administrator needed.
   • Linux: JClean_linux_amd64.deb for Ubuntu, Debian and Mint, or JClean_linux_x86_64.AppImage for any other distribution. 64-bit.

   Checksums are in SHA256SUMS.txt.

   Opening JClean the first time on a Mac

   This version isn't notarized by Apple yet, so macOS asks you to confirm once:

   1. Open the DMG and drag JClean into Applications.
   2. Open JClean. macOS says it can't verify the app. Click Done (not "Move to Trash").
   3. Open System Settings → Privacy & Security, scroll down to "JClean was blocked to protect your Mac", and click Open Anyway. Confirm with your password.
   4. JClean opens. From now on it opens normally.

   Installing on Windows

   The installer isn't code-signed yet, so Windows SmartScreen may say it "protected your PC". Click More info, then Run anyway. You only see this when installing; updates install from inside JClean.

   Installing on Linux

   • .deb: sudo apt install ./JClean_linux_amd64.deb
   • AppImage: chmod +x JClean_linux_x86_64.AppImage, then run it. On Ubuntu 22.04 and later, install FUSE 2 first: sudo apt install libfuse2t64 (libfuse2 on 22.04).

   Both update themselves from Settings → Updates. On GNOME, the tray icon needs the AppIndicator extension (Ubuntu has it already).

   JClean is open source, reads only file sizes and dates, and never sends anything off your computer.
