OneDown

Permanently delete files from the Finder toolbar.

OneDown adds a Delete Forever button to your Finder toolbar. Select files, click once, confirm — gone for good. No Trash, no recovery.

Companion to OneUp — the Go Up button for Finder.

Install

1. Download the DMG from Releases
2. Drag OneDown.app to /Applications
3. Open it — macOS will block it (no notarization). Go to System Settings → Privacy & Security → Open Anyway
4. The Delete Forever button appears in Finder toolbar automatically

How it works

• Main app installs DeletePermanently.applescript into ~/Library/Application Scripts/
• The Finder Sync Extension adds a toolbar button
• On click, the extension runs the script via NSUserAppleScriptTask (outside sandbox)
• The script asks Finder for the current selection, shows a confirmation dialog, then runs rm -rf

Requirements

• macOS 13.0 (Ventura) or later
• Apple Silicon or Intel
