How to Open on macOS in 5 Seconds
Because this is a private pre-release test build that hasn't gone through Apple's $99/year App Store signing yet, macOS Gatekeeper may show a warning when you open it for the first time. Here is how to open it:
System Settings (Fastest)
When macOS blocks it, open System Settings → Privacy & Security, scroll down to the Security section, and click "Open Anyway".
Finder Right-Click
In your Applications folder, right-click (or Control-click) Dave Cleaner, select Open, then click Open on the prompt.
Terminal (1-Line Fix)
Run this single command in Terminal to instantly remove the browser download quarantine flag:
xattr -cr /Applications/"Dave Cleaner.app"
Key Features to Test
Here are the key areas we would love your feedback on during this test run:
1. Ultra-Fast POSIX Deep Scan
Click "Run Scan" and observe the speed. Dave Cleaner uses low-level POSIX filesystem calls and concurrent queues to scan hundreds of thousands of files in under 2 seconds.
2. SHA-256 Duplicate Detector
Check the "Duplicates" category. Dave Cleaner groups identical files and provides an "Auto-Select Dupes" button to quickly clean up redundant downloads and copies.
3. Live Menu Bar Companion
Look at your Mac's top menu bar! Click the Dave Cleaner drive icon to view live Macintosh HD disk storage, live RAM memory pressure, and quick 1-click scan triggers.
4. Zero-Risk Trash Deletion
Test moving safe items to the Trash. Dave Cleaner never permanently deletes files; everything is safely recycled to ~/.Trash, and only pre-approved cache paths can be auto-cleaned.
