Securely Delete Files
Mac OS X, Security, Tips & Tricks - November 9th, 2009 - No Comments
You can securely delete files by going to the Finder menu and down to “Secure Empty Trash”, which actually writes zeros over the data rather than just freeing up the space. This is particularly useful for removing any sensitive data or files you don’t want anyone else to dig up, like when you’re transferring your Mac to a new owner. Note that deleting files in this secure manner takes longer than the typical file deletion method.
