Permanent Eraser
Permanent Eraser is a file-deletion utility for macOS that securely wipes files from your Mac using the Gutmann Method, which overwrites data thirty-five times before removing it completely. Unlike macOS's standard Trash, which simply marks files as deleted while leaving the data recoverable, Permanent Eraser makes files unrecoverable by traditional means. It supports erasing individual files via drag-and-drop, emptying the Trash securely, wiping rewritable CDs and DVDs, and integrates with Finder through toolbar buttons and contextual menu options. It is used by privacy-conscious users, security professionals, and anyone handling sensitive data who want military-grade file deletion.

1 suggestionPermanent Eraser has not been updated since version 2.9.1, released around 2010. The app remains Intel-only with no native Apple Silicon build, and the developer (Eden Waith) appears to have abandoned the project. The app will continue to run under Rosetta 2 today, but Apple is removing Rosetta from macOS 28 in September 2028, at which point Permanent Eraser will stop launching entirely. If you rely on secure file deletion, you should evaluate modern alternatives now. Permanent Eraser's core job — securely wiping deleted files — is partially addressed by macOS's own Secure Empty Trash feature (built into Finder), which is sufficient for most users. For users who want third-party tools, consider Permanent Eraser's successors like CCleaner (which includes secure deletion and runs natively), Trash It, or the simpler built-in approach of upgrading to a current macOS version where Secure Empty Trash is enabled by default in Finder's settings. Starting the transition now will give you time to move your secure-deletion workflow before Rosetta 2 vanishes.
