macOS-SnapCleaner

SnapCleaner is a lightweight macOS tool that automatically deletes local Time Machine snapshots as soon as they are created.
It is designed for users who want to avoid local disk space being taken up by snapshots while still using Time Machine for external backups.

⚠️ Note: SnapCleaner has been tested on macOS Tahoe. Other versions may work, but are untested.
