ShredIt X

You cannot shred a file, if you are using an SSD. You might not be able to shred a file (completely), if you're using a Fusion Drive. Even if you're using an HDD, you might not be able to shred a file, if you're using a journaled HFS+. If you use APFS, you cannot shred a file. There is a very good reason why Apple removed "Secure Empty Trash" and the srm command line program from macOS, because they don't want to give their customers a false sense of security: shredding is probably impossible with modern devices and modern filesystems, and users should be aware that they are buying products from snake oil salesmen, if developers claim they can "shred" your files. Use File Vault 2 whole disk encryption instead and just delete/rm your files the normal way.

To MacUpdate: Shredit.app version 6.0.3 is only Intel. Valid for OSX.6 Snow Leopard. Not for OSX.5 (Universal Binary, valid on PowerPCs or Intel Mac).

PREVIOUSLY REGISTERED USERS: note that this version of the app seems to implement a new two-field registration scheme. a single (old) registration code no longer works.

Pretty much works perfect and the schedular is great you can leave it to do a free space wipe during the night while you sleep. Yeah good app and does what it says on the box. I tested it with some recovery software it does mess up recovery. You run this those files are really gone forever. BTW I see a unix command put here NEVER USE THIS COMMAND unless you know about unix. That one is a crazy command! :) I am not sure on OSX rm does a secure delete? Don't you need to pipe to a program like shred/gshred like on Linux/BSD?

Get On My Command contextual menu and choose delete files 7 up to 32 times. You can delete any files or folders anytime.

This is exactly what I needed. Thanks. Great app! :)
