Mac System Data Cleaner by Universally Thinking

Reclaim the space hiding in System Data.

Scan your Mac for caches, logs, developer leftovers, and other files that inflate System Data. Check exactly what to delete — unchecked items stay. Confirm with DELETE before anything is removed.

Mac System Data Cleaner showing scan results and delete selection — Scan, filter, and delete with checkboxes

What it does

An interactive Python tool (terminal or localhost web GUI) that finds common space hogs under your home directory, shows size and risk, and only removes what you mark — never silently.

Targeted scans

User caches, logs, crash reports, Xcode/Gradle/npm caches, Homebrew, iOS backups, Time Machine snapshots, Trash, and optional large Downloads.

You choose what goes

Checkboxes per item. Low-risk items can be pre-selected; high-risk paths need an explicit opt-in.

Safety first

Stays under your home directory (plus Homebrew cache / TM snapshots). Blocks top-level folders like Documents. Requires typing DELETE.

Terminal or web GUI

Run mac-clean in the terminal, or mac-clean-web for a localhost UI at port 8765.

What it scans

Caches — ~/Library/Caches, browsers, package managers
Developer tooling — Xcode DerivedData / Archives, Gradle, npm, pip, cargo, Android
iOS device backups and old Xcode device support files
Local Time Machine snapshots and Trash
Optional large files in Downloads
