Your Mac, But Faster
A native macOS system optimization app built with SwiftUI and a high-performance Rust disk scanner.
30+ tools to monitor, clean, and maintain your Mac from a single dashboard.

- Home Dashboard -- Overview cards with system health insights, disk usage ring chart, and quick actions
- Memory -- Live memory pressure gauge, per-process RSS tracking, growing process detection
- CPU -- CPU-intensive process list with quit/force-quit, smart self-detection when scanning
- Battery -- Battery health %, charge cycles, thermal state, configurable auto-refresh (10s/30s/60s)
- Network -- Real-time upload/download bandwidth and active connections
- Disk Health -- S.M.A.R.T. monitoring for SSD/HDD status
- Quick Clean -- One-click safe junk cleanup (caches, logs, temp files) with single confirmation
- Cache Cleanup -- 18 cache categories with smart risk levels:
- App Caches, System Logs, Xcode Data, Package Managers (Homebrew, npm, pip, Conda, CocoaPods, Bun, Flutter)
- Browser Caches, Containers & VMs (Docker, Parallels, VMware, UTM, VirtualBuddy)
- JetBrains IDEs, VS Code & Cursor, Communication Apps (Slack, Discord, Teams, Zoom)
- Game Libraries (Steam, Epic), AI & ML Models (Ollama, Hugging Face, LM Studio, PyTorch)
- Installer Packages, Time Machine Snapshots, Temporary Files, Language Files
- Disk Analysis -- Rust-powered scan with sortable largest folders, drag-and-drop scan roots
- Duplicate File Finder -- SHA256-based detection with partial hash optimization (first 8KB + last 8KB)
- Docker Management -- Images, volumes, containers; bulk prune; disk usage stats
- File Shredder -- Secure 3x-overwrite deletion
- Maintenance -- System scripts (flush DNS, rebuild Spotlight, verify disk, repair permissions)
- Electron apps (Slack, Discord, Claude) marked as "Moderate" risk -- may require re-login after cleanup
- Pure caches (pip, Homebrew, Xcode DerivedData) marked as "Safe" -- auto-regenerate
- "Select All Safe" never touches login-sensitive data
- Every category shows "What breaks if deleted" info
- Login Items Manager -- Control startup agents and daemons
- Privacy Scanner -- Browser cache/cookie/history cleanup, app permission scanner
- App Manager -- Full app uninstaller with associated file detection
- Extension Manager -- Safari, QuickLook, input methods, screen savers
- Screenshot Organizer -- Find and clean up screenshots from Desktop/Downloads
- Startup Time Analysis -- Boot time analysis and startup contributors
- Disk Benchmark -- Sequential and random read/write speed tests
- Audit Log -- Full trail of all actions with timestamps, paths, bytes freed (exportable)
- Menu bar widget with compact gauges (Memory, Disk, CPU) and quick actions
- 5-step onboarding wizard for new users
- Multi-step confirmation dialogs for all destructive actions
- Light / Dark / System theme support
- Keyboard shortcuts (Cmd+1..9)
- Settings with configurable poll intervals and scan presets

Download the latest .dmg from Releases.
Note: This app is not signed with an Apple Developer ID. macOS will show a security warning -- this is expected for open-source apps distributed outside the App Store. The full source code is available on this repo for verification.
First launch (one-time setup):
- Open the
.dmgand drag MacOptimizer Studio to Applications - Try to open the app -- macOS will block it with a warning
- Go to System Settings → Privacy & Security
- Scroll down -- you'll see "MacOptimizerStudio was blocked from use because it is not from an identified developer"
- Click "Open Anyway" → enter your password → click "Open"
- You only need to do this once -- the app opens normally after that

- Every destructive action requires multi-step confirmation
- Smart risk levels per cache item (Safe / Moderate / Caution)
- All operations are logged to the Audit Log with timestamps and file paths
- Audit trail is exportable as a text file
