If you do not want FileVault, and want a srm tool, then follow the suggestions from sesser and install your own flawed tool, which keep Apple libel free. This will get even better when the new file system in Sierra is more commonly used by Mac users. Accidentally or mistakenlly deleted files from trash or directly emptied the Trash bin without checking the detailed files.
If you are concerned about sensitive data, you should be using System Preferences -> Security -> FileVault, so that deleted files are just a bunch of random bits. Earlier models of Mac, prior to the software update macOS Sierra, enabled users to permanently and securely delete files with the click of a button: Secure. Step 3 Drag a file from Finder to the Terminal window, then hit Enter button. Step 2 Type the command: srm -v followed by a space. Step 1 Go to 'Finder' > 'Applications' > 'Utilities', find and open up Terminal. SSDs never write to the same place twice, then constantly remap pre-cleaned sectors to the old logical offset, and SSD bad block replacement moves a bad sector out of service, and again can be read with the right software.Ī company like Apple, that gets sued because they have money in the bank, cannot afford to have a service or utility that claims it provides a secure delete if it does not 100% provide that service. Whatever the reason is, there is a way you can force empty trash on Mac. A rotating disk will do bad sector replacement, but data can be read from bad sectors with the right tools. When you 'securely empty' the trash, your computer will write a series of 0s over the old data, effectively destroying it. Because of how modern disk drives work there was NEVER a way to truly secure delete.
