Systematic Cleaner

Install

System requirements

  • macOS: 12 or later, on Apple silicon or Intel.
  • Windows: 10 or 11, 64-bit.
  • Linux: 64-bit, on x64 or ARM. Tested on Ubuntu 22.04 and later.

Systematic Cleaner is free. It needs no account and shows no ads.

Install on macOS

  1. Download the .dmg for your Mac: Apple silicon for M1 and later, Intel for older Macs. Not sure? Open the Apple menu, choose About This Mac, and look for Chip (Apple silicon) or Processor (Intel).
  2. Open the .dmg and drag Systematic Cleaner to Applications.
  3. Open it from Applications. If macOS asks you to confirm the first time, open System Settings → Privacy & Security and choose Open Anyway.

Install on Windows

  1. Download the installer (.exe) and run it.
  2. Windows asks for administrator permission: the app installs for every user of the computer, in Program Files.
  3. Open Systematic Cleaner from the Start menu or the desktop shortcut.

A portable version runs without installing. It does not update itself and cannot start with Windows; to update it, close the app and replace its files with the newest portable download. Your settings are kept.

Install on Linux

  • Debian, Ubuntu and similar: download the .deb and install it with sudo apt install ./SystematicCleaner-*.deb, then open it from your applications menu.
  • Any distribution: download the AppImage, make it executable with chmod +x SystematicCleaner-*.AppImage, and run it.

Every Linux download: x64 .deb, x64 AppImage, ARM .deb, ARM AppImage.

First launch

  1. Choose your language: English, French or Arabic. The app starts in your computer's language when it is one of these. You can change it any time in Settings.
  2. Recommended setup: choose whether the app starts with your computer, keeps running in the tray when you close it, and cleans automatically every Monday at 9:00. All three are optional.
  3. Home opens with live use, free space and the state of every check.

Administrator rights

Some tools change the system and need administrator rights: the registry cleaner, services, drivers, system file repair and some privacy settings. When the app is not running as administrator, those pages show a Relaunch as Admin button. On macOS and Linux, the system asks for your password when a change needs it.

In Settings, Prefer administrator on launch asks for these rights every time the app starts. It is off by default.

Your first clean

  1. Open System Cleaner and choose Scan.
  2. Review the results. Each category lists what it found and its size; open a group to see every file, or search by app, file name or path.
  3. Untick anything you want to keep, then choose Clean and confirm.

Nothing is deleted without your confirmation. Files changed in the last hour are skipped, the Recycle Bin is protected, and folders you exclude in Settings → Exclusions are never touched. You can change all of these in Settings. Each cleanup is recorded under Activity.

Updates

The app checks for its own updates in the background and installs them on the next restart. Turn this off, or choose how often it checks, in Settings.

Uninstall

  • macOS: quit the app and move it from Applications to the Trash.
  • Windows: open Settings → Apps → Installed apps, choose Systematic Cleaner and Uninstall.
  • Linux: sudo apt remove systematic-cleaner, or delete the AppImage.

Registry and context-menu backups stay in Documents/Systematic Cleaner Backups until you delete them.
