Summary: Finding the best way to delete files on Mac Hard drive permanently? This blog discusses the most effective ways to erase files quickly. You can also download a powerful file eraser tool, such as BitRaser File Eraser to wipe data from a Mac hard drive beyond the recovery scope.

In Mac systems, unlike Windows, you don’t delete but erase files. However, this file erasure in Mac is similar to file deletion in Windows.

In other words, when you erase a file in Mac, only the pointer location to the file is deleted from file system journal. However, the actual file and data remain on the Mac hard drive unless overwritten.

Thus, to permanently delete and secure erase data from a Mac hard drive, you need to overwrite it deliberately with the help of a secure data erasure standard such as DoD 5220.22-M, NATO, etc.

In Mac, you can do this via Disk Utility, Terminal Command, and by using a secure file erasure tool such as BitRaser for File Mac.

  1. Steps to Permanently Delete Mac Files with Disk Utility

IMPORTANT NOTE: With the first two methods—Disk Utility and Terminal Command—you can’t permanently delete individual files from Mac hard drive. These two methods can help you wipe a Mac hard drive volume (other than the system volume) or physical external hard drive with DoD 5220.22-M standard.

Thus, if you want to permanently delete or secure erase individual or only a few selected files from Mac drives, skip to the last steps to permanently delete files on Mac with secure file erasure software.

On your Mac system,

  • Click on Launchpad and open ‘Disk Utility’ under Utilities
  • Choose the hard drive volume that contains files that you want to remove
  • Click on ‘Erase’ button at the top
  • Enter a volume ‘Name’, choose a ‘Format,’ and click ‘Security Options…
  • Move slider to ‘Most Secure’ and click ‘OK.’

The ‘Most Secure’ security option is slowest. It implements U.S. DOD 5220.22M (7-pass) secure data erasure standard to erase every bit of information from your Mac hard drive.

  • Click ‘Erase

If Disk Utility fails to wipe the disk, use diskutil Terminal Command discussed in the next method to secure-erase files from a Mac hard drive.

  1. Steps to Permanently Delete Files on macOS with Terminal Command

IMPORTANT NOTE:With secure-erase terminal command, you can’t secure erase a particular hard drive volume. It securely wipes the entire disk. But you can use the Terminal to securely wipe empty storage space on a Mac hard drive volume.

  1. Go to Application> Utilities and open the Terminal app

CAUTION: Terminal is a powerful command-line tool in Mac. A minor typo in the command can lead to chaos and may turn your Mac machine into an expensive paperweight. Use it cautiously

  1. Type diskutil list

This command lists all the connected hard disks and volumes. Note down the disk number of Mac hard drive volume that you want to erase.

  1. Type diskutil secureErase 2 disk#

Replace # with the hard disk number. The command will erase the selected Mac hard drive with US DoD 5220.22M (7-pass) erasure standard

If you wish to wipe only free space on the Mac hard drive, enter the following command in Terminal window and press ‘Return’ key,

diskutil secureErase freespace 2 disk#s#
Again, replace # values with the hard disk volume number
