When you normally delete your files in Mac OS X, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with Mac OS 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times.

Permanent Eraser provides an even stronger level of security by implementing the Gutmann Method. This utility overwrites your data thirty-five times, scrambles the original file name, and truncates the file size to nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means.

Work Great For Me

No nickname chosen.

I have always wanted a strong and simple secure deletion program that completly deleted files well beyond the point of recovery. Permenant Eraser fits the bill. I rely on it much more than I rely on OS X’s Secure Empty Trash function when needing to delete sensitive data. It is simple, lightweight, and even has Automator actions to delete files straight from the Finder window. All in all, It is a great app for the secure deletion of sensitive information.

Note that Permenant Eraser cannot delete files that you don’t have write access to. Check your file’s permissions before giving up.



For those people who claim that the app is not working: I got the same problem on Sierra, and undestood that original app released Feb 2012 must be adopted by developer to the current moment.
Just click «Permanent Eraser Support» link at top right corner at this window (Mac AppStore) and download updated actual version from developer’s page. And it’s 100% working. I love this small app because it can be added (in app’s preferences) to right-click Mac context menu to Services and therefore becomes very convenient and available directly from Finder list.

Works Better than Finder Empty Trash


Had been using "Secure Empty Trash" within finder for a long time now and found it to be slow and difficult to use. Permanent Eraser is faster, easier to use, and works great with an Automater iCal event to run it on a daily basis. Thanks for a great app and I would recommend this to anyone (and have).
