Permanent Eraser
Permanent Eraser is a secure file deletion utility for macOS that permanently overwrites files before removing them from the system. Instead of relying on the standard Trash deletion, which only removes file references while leaving data recoverable, Permanent Eraser uses the Gutmann Method to overwrite each file thirty-five times, scramble the original file name, and truncate the file size before unlinking it from the system. The utility integrates with the Finder toolbar and contextual menus, and can also erase CD-RW and DVD-RW media. It is used by privacy-conscious users, security professionals, and anyone handling sensitive data who needs stronger assurance of permanent deletion.
AI Recommendation
1 suggestionPermanent Eraser has not received a meaningful update since the late 2000s—the most recent version we could identify is 2.7, released around 2015, and there is no evidence of a native Apple Silicon build. The app will continue to run under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (September 2028), after which this Intel-only build will no longer launch. If you rely on Permanent Eraser for sensitive file deletion, you have two options: contact the vendor (Edenwaith) directly to inquire whether a native build is planned before September 2028, or migrate to an actively maintained alternative. For secure file deletion, consider using macOS's own Secure Empty Trash (built into Finder since macOS 10.3), which provides DOD-level overwriting for files in the Trash, or look at third-party utilities like Permanent Eraser's modern successors such as CleanMyMac X (which includes secure deletion features and runs natively on Apple Silicon) or secure-deletion utilities available on the Mac App Store. If you only need to securely erase free space on your drive, the command-line utility `diskutil secureErase freespace` offers a free native option.
