What is secure erasing a file on Mac?
Secure erasing a file is removing the file completely from your Mac. What this means is, is that a file that is securely erased cannot be recovered by you or any third-party applications; it's the ultimate way to completely get rid of files.
See, when you typically empty the Trash, you're just deleting the access point to the file. Think of it like… a file is written on paper (your Mac) in pencil, and you erase the file with an eraser — You can still see the marks that were made on the paper! But, when you secure erase, you rewrite gibberish over the original pencil marks, and then erase it: there's no way to read it (it can't be recovered)!
So, there are two ways we can securely erase a file: one is via a Mac utility with a secure eraser and the other is with the Trash.
How to securely erase files using the 'rm' command
Previously, you could securely delete files on your Mac using the “rsm” command in Terminal. Apple has eliminated this option with the introduction of the macOS Sierra. But, there is still a way to safely delete files using the “rm” command.
Firstly, you need to enable some settings in System Preferences.
- Open System Preferences (Apple menu > System Preferences)
- Select the Keyboard.
- Go to the Shortcuts tab.
- Enable New Terminal at Folder and New Terminal Tab at Folder.
Now, you need to go to Finder and find the folder that stores the file you want to delete securely. https://yellowgig322.weebly.com/how-to-uninstall-apps-on-macos-mojave.html. Right-click it and choose New Terminal at Folder. Now the Terminal window should open.
In the Terminal window:
- Enter
rm -P PrivateFile.txt
command, but instead of “PrivateFile” use your file name. Instead of “txt” use the extension your file has. - Press Enter.
And your file is gone!
When entering your file name in Terminal, make sure you write it correctly. If your file name has a space like, My File, you need to put the name in brackets like this “My File.docx”

- Open Disk Utility (Applications > Utilities > Disk Utility).
- Select your drive in the External category on the left. Make sure you don’t erase your internal hard drive. It contains all your data and you won’t be able to restore it once erased.
- Click the Erase button.
- Type a name for your drive and choose a format. Apple recommends using ExFAT format.
- Press Erase to confirm. If you drive is successfully erased, you should see a message like this:
Safely erase multiple files using an encrypted disk image
Disk images (.dmg) provide a secure way to store and share your private files. You can store your disk image in any cloud storage, on your Mac or external hard drive. And given the fact that you can encrypt the disk image, no one will be able to access your data.
If you want to delete multiple sensitive files and data in one go, you can use a disk image as well. You’ll need to create an encrypted .dmg file and transfer your files there. Then, you can lock the disk and delete it, making your data unrecoverable for anyone. Here’s how to do that step-by-step: Ds apps for mac os.
- Open Disk Utility (Applications > Utilities > Disk Utility).
- Go to File, select New Image, then, Blank Image.
- Type your disk name in the Save As field. Make sure to add the .dmg extension.
- Type size and choose format.
- Select the Encryption method. Apple recommends the first method (128-bit AES encryption).
- Provide a password to encrypt your disk image and press Choose.
- And press Save.
Now you can drag and drop the files you want to delete to the disk image. Then, right-click the disk image and press Eject to lock it.
Move this disk image to the Trash and you’re done. Though your files are now in the Bin, no one can access them without your encryption key. Empty the Trash to let your sensitive files be gone forever!

The majority of people believe that moving a file into Trash and emptying it will erase the file from their computer.
The harsh truth is that the computer does not completely erase that file, it just makes the file invisible to the user and marks that part of the disk the file was stored on as ‘available’.
This means the operating system is free to overwrite the file with new data and will do so in the coming days, weeks or months. But it is worth emphasizing that until that happens, your ‘deleted’ data is still on the disk and can be recovered with the right tools.

Security experts recommend encryption for flash drive users.
