A native macOS application for system monitoring, disk analysis, and cleanup. Built with SwiftUI for macOS 14+.

• Dashboard: Real-time system metrics (CPU, memory, disk, battery, Bluetooth devices)
• Cleaner: Scan and remove caches, logs, and temporary files
• Analyzer: Visual disk space analysis with interactive navigation
• Optimizer: System optimization tasks (DNS flush, Spotlight reset, font cache rebuild, etc.)
• Apps: View installed applications and uninstall with related file cleanup
• History: Track all cleaning operations
• Scheduled tasks: Automate cleanup routines

DodoTidy is a free and open-source alternative to paid macOS system cleaners like CleanMyMac X, MacKeeper, and DaisyDisk. It offers comparable features without the subscription fees or one-time purchase costs.

DodoTidy is designed with multiple safety mechanisms to protect your data:

All file deletions use macOS's trashItem() API, which moves files to Trash instead of permanently deleting them. You can always recover accidentally deleted files from Trash.

The following paths are protected by default and will never be cleaned:

• ~/Documents - Your documents
• ~/Desktop - Desktop files
• ~/Pictures, ~/Movies, ~/Music - Media libraries
• ~/.ssh, ~/.gnupg - Security keys
• ~/.aws, ~/.kube - Cloud credentials
• ~/Library/Keychains - System keychains
• ~/Library/Application Support/MobileSync - iOS device backups

You can customize protected paths in Settings.

Safe auto-clean paths (used by scheduled tasks):

• Browser caches (Safari, Chrome, Firefox)
• Application caches (Spotify, Slack, Discord, VS Code, Zoom, Teams)
• Xcode DerivedData

Manual-only paths (require explicit user action, never auto-cleaned):

• Downloads - May contain important unprocessed files
• Trash - Emptying is IRREVERSIBLE
• System logs - May be needed for troubleshooting
• Developer caches (npm, Yarn, Homebrew, pip, CocoaPods, Gradle, Maven) - May require lengthy re-downloads

Enable "Dry run mode" in Settings to preview exactly what files would be deleted without actually deleting anything. This shows:

• File paths
• File sizes
• Modification dates
• Total count and size

Set a minimum file age (in days) to only clean files older than a specified threshold. This prevents accidentally deleting recently created or modified files.

Example: Set to 7 days to only clean files that haven't been modified in the past week.

When "Confirm scheduled tasks" is enabled (default), scheduled cleaning tasks will:

• Send a notification when ready to run
• Wait for user confirmation before executing
• Never auto-clean without user review

DodoTidy operates entirely within user space:

• No sudo or root privileges required
• Cannot modify system files
• Cannot affect other users' data
• All operations limited to ~/ paths

The optimizer only runs well-known, safe system commands:

• dscacheutil -flushcache - Flush DNS cache
• qlmanage -r cache - Reset Quick Look thumbnails
• lsregister - Rebuild Launch Services database

No destructive or risky system commands are included.

The app uses a provider-based architecture:

• DodoTidyService: Main coordinator that manages all providers
• StatusProvider: System metrics collection using native macOS APIs
• AnalyzerProvider: Disk space analysis using FileManager
• CleanerProvider: Cache and temporary file cleanup with safety guardrails
• OptimizerProvider: System optimization tasks
• UninstallProvider: App uninstallation with related file detection

All providers use Swift's @Observable macro for reactive state management.

Access Settings from the app menu or sidebar to configure:

• General: Launch at login, menu bar icon, refresh interval
• Cleaning: Confirm before cleaning, dry run mode, file age filter
• Protected paths: Paths that should never be cleaned
• Notifications: Low disk space alerts, scheduled task notifications

• Primary color: #13715B (Green)
• Background: #0F1419 (Dark)
• Text primary: #F9FAFB
• Border radius: 4px
• Button height: 34px
