Dissectmac

Dissectmac is a Mac disk space analyzer and cleaner that draws every folder on your drive to scale, helping you find what's taking up space and clear it. It targets the hidden locations where macOS stores caches, developer build files, and leftovers from deleted apps — areas Finder doesn't surface.

Key Features

• Storage map drawn to scale: Every folder appears as a block sized by the space it uses, so the biggest space consumers are the largest shapes. Click into a block to go deeper.
• Search and filters: Search across your Mac by name, or filter to specific culprits such as Xcode, Docker, node_modules, disk images, archives, and iOS backups.
• App uninstaller with leftover cleanup (Pro): Remove an app together with the containers, caches, and preference files it leaves behind, and clear leftovers from apps deleted earlier.
• Delete inside the app (Pro): Select what you don't need and move it to the Trash from within the app; files go to the Trash first rather than being erased.
• Live monitor (free): View live CPU, memory, and battery stats alongside storage information.
• System Data visibility: Opens up the System Data (or Other) category folder by folder, showing what macOS hides behind the grey bar in Settings.

Typical Use Cases

• Reclaiming space from developer files: Find accumulated Xcode DerivedData, Docker disk images, node_modules copies, and local AI models across old projects in a single scan, then clear what's safe.
• Uninstalling apps completely: Remove an app and the support files, containers, and preferences it left in ~/Library/Application Support.
• Investigating System Data: See what's inside the System Data category, which is usually 10 to 30 GB, and clear the parts that are safe.
• Diagnosing a slow Mac: Use the live monitor to find what's consuming CPU and memory, then address it.

How It Works

1. Click Scan Full Mac; Dissectmac reads every folder on the drive, including hidden Library folders. A 500 GB drive takes about a minute.
2. View the drive as a map where each folder is a block sized by its space usage; click into blocks, search by name, or apply filters.
3. Select what you don't need and move it to the Trash from inside the app, or uninstall an app with its leftover files.

Who It's For

Dissectmac suits Mac users who want to understand where their disk space goes before deleting anything — particularly developers dealing with build artifacts, container images, and dependency folders, and anyone puzzled by a large System Data category. The free version maps the whole drive; Pro adds in-app deletion, the app uninstaller, and leftover cleanup for a one-time $12.99 payment with a lifetime licence and no subscription.

Dissectmac gives Mac users a clear, folder-by-folder view of their storage and the tools to act on it, making it a practical choice for anyone who wants to reclaim gigabytes without guesswork.
