Everything NythyCleaner does for your Mac
NythyCleaner is a comprehensive macOS utility that goes far beyond clearing caches. It covers your entire desktop lifecycle: storage analysis, exact duplicate detection (SHA-256), system maintenance, real-time monitoring, privacy auditing, extension management, and automated cleanup. One tool, zero fragmentation.
System cleanup
Scans and removes temporary files, user and system caches, logs, browser data, forgotten downloads, and accumulated clutter. See exactly what takes up space before deciding what to remove.
- 15+ categories: caches, logs, temp files, browser data (Safari, Chrome, Firefox, Edge, Brave, Arc…), iOS backups, Mail downloads, VM files.
- Donut and bar charts to visualize disk composition.
- Top 30 largest files detected in Documents, Desktop, and Downloads.
- Browser extensions listed with sorting by size, browser, or name.
- Weekly cleanup history chart to track progress over time.
Disk space and treemap
Maps every folder on a volume into an interactive treemap so you can see exactly where storage is used. Supports internal drives, external drives, and connected iPhones.
- Visual treemap proportional to each folder’s size with breadcrumb navigation.
- Volume selection strip for mounted disks, external drives, and iPhones.
- Large and inactive file scanner with customizable size and age thresholds.
- Volume actions: mount, unmount, eject, rename, verify, repair.
- External volume formatting (APFS, HFS+, ExFAT, FAT32) and expert diskutil sheet.
Exact duplicate detection (SHA-256)
Finds byte-for-byte identical files: walks folders you choose, buckets by size, then verifies with a full SHA-256 hash (native C++ pipeline). Analysis stays on your Mac.
- Works on any regular file above size thresholds (documents, archives, images, videos).
- Names and dates may differ; content is what matters.
- Auto-select protects at least one copy per group.
- Results cached for 24 hours for instant reload.
Xcode, Homebrew, and Docker cleanup
Reclaim tens of gigabytes of accumulated developer data: DerivedData, archives, simulators, package caches, provisioning profiles, and 20+ Xcode locations.
- 20+ Xcode categories in 6 groups: Build, Devices, Caches, Packages, Profiles, User Data.
- Purge unavailable simulators via simctl.
- Homebrew tab: dry-run analysis and developer dependency scanning (node_modules, venv, Pods…).
- Docker tab: containers, images, volumes, and docker system prune.
Real-time monitoring
Track your Mac’s performance live: CPU, memory, GPU, Neural Engine, network, disk I/O, thermal state, and battery. Live charts update every second by default.
- 10 tabs: Overview, CPU, Memory, GPU, ANE, Network, Disk, Processes, Battery, History.
- Adjustable refresh rate: 0.5, 1, 2, or 5 seconds.
- CPU core control: individual core offlining/onlining via cpuctl.
- Network diagnostics: DNS, ping, Wi-Fi signal (SSID, RSSI, channel, noise).
Privacy audit
Audits your Mac for sensitive traces left by browsers, the system, and connected devices. Privacy score from 0 to 100, selective cleaning, and secure file destruction.
- 4 parallel checks: browser data, app permissions, system traces, network history.
- Privacy score from 0 to 100 with color-coded gauge.
- Secure delete: Zero Fill (free), DoD 3-pass and 7-pass (Pro).
- Direct link to macOS Privacy & Security settings.
Complete uninstaller
Finds every installed application and detects their associated files scattered across Library. Select an app, scan for leftovers, then delete everything in one step.
- Auto-scan of Application Support, caches, preferences, containers, launch agents, daemons.
- Risk badges per file: safe, neutral, caution, danger.
- Batch uninstall and system app protection with warning.
System maintenance and updates
Dozens of one-click maintenance tasks: DNS, Spotlight, memory, permissions, Dock, Finder, developer caches, security. Plus update detection for all your apps.
- Tasks organized in 9 categories: System, Network, Finder, Privacy, Developer, Hardware, Screenshots, Keyboard, Security.
- Update detection via Homebrew, Sparkle, Electron/GitHub, and Mac App Store.
- Developer packages: 15+ managers (npm, pip, Cargo, Go, Flutter, Dart…).
Extensions and startup items
Lists everything that starts automatically or extends macOS: login items, Quick Look, Spotlight, launch agents, and launch daemons. Enable or disable each entry.
- 5 categories: Login Items, Quick Look, Spotlight, Launch Agents, Launch Daemons.
- Apple entries filtered automatically — system services never appear.
- Bulk actions: Enable all, Disable all, Remove invalid entries.
Scheduled cleanup
Automates recurring cleanup: caches, logs, temporary files, Xcode, Homebrew, and Trash — without manual intervention.
- 4 frequencies: daily, weekly, biweekly, monthly.
- 7 categories in 3 groups: System, Development, Maintenance.
- macOS notification after each automatic run.
- Run now button for immediate cleanup.
