The honest, open-source disk cleaner for macOS.
MacCleaner is for you.
MacCleaner is a powerful system utility. While it is designed to be safe by moving files to the Trash, the author is NOT responsible for any data loss, system instability, or accidental deletion of important files. Always ensure you have a full system backup (Time Machine) before performing any cleaning operations.
No ads. No subscriptions. No hidden tracking. Just a simple, powerful tool to reclaim your hard drive space safely. Built by a developer, for everyone.
