Very similar to the process we covered with Disk Utility, this makes it nearly impossible to recover or open once deleted, and it works for individual files, not just all free space on the disk.ġ3 Terminal Commands Every Mac User Should Knowĭelete files securely in Mac OS X Leopard Incinerator is a free Mac application that will write over your files up and beyond 50 times before deleting it. You can use a file "shredder" program to securely remove individual files from your computer. This method should only be used if you are sure the files you delete are not vital to the system itself or you could cause irreparable harm to your Mac. If you want to delete a volume, like a Time Machine backup, replace that with -rfv. If you're deleting a folder, add in -rf like before. For a file, use srm followed by a space and then -s for one-pass overwrite, followed by another space, and then your file.įor max overwriting, don't use anything, just be prepared to wait if it's a large file. To securely erase the files from Terminal, use the command for secure remove. It doesn't overwrite the files like Disk Utility and "Secure Empty Trash" does. This will remove any file you want from your computer regardless of any error it may cause.īut, these two options above only delete them like you're emptying your trash. If you need to delete a folder, input rm followed by a space and -rf (to force it to work) followed by another space, then drag and drop your folder (it also works with files). Unlike using the Trash can, you can't undo this, so be careful. Then just hit enter/return and the file should be removed from your computer. If you have some top secret files that you really want to get rid of, remove them completely from your computer by using the "Secure Empty Trash" option instead of just "Empty Trash". Simply emptying the trash will still allow you (or someone else) to recover those files with a file recovery program. While emptying the can will free up space on your hard drive, those files are still on your device, just waiting around until they are eventually overwritten by newer data. But, there is one problem with emptying the trash can-it does not actually delete it. I empty my trash on a daily basis because I simply hate having that crumbled up piece of paper in the bin. Here are just a few ways that I found to go beyond simply tossing files into the recycle bin and trashing them on your Mac computer. So, I figured it was time to add some Bond to my daily life by beefing up on my data deletion know-how, since I have a lot of spy-worthy (and embarrassing) content on my Mac that probably shouldn't be there. Don't get me wrong, it was a solid flick, but only made me jealous with all its super spy hacker stuff. This Mac 911 article is in response to a question submitted by Macworld reader Vince.I was kinda disappointed with last year's James Bond movie, Skyfall. Select Delete Immediately and confirm the deletion. Select one or more files in the Trash and Control-click. However, it’s changed further: you can no longer trigger it anywhere in the Finder except in the Trash folder. Within the Trash folder, you can delete items without any further ado. Apple added this option in El Capitan after it ditched Secure Empty Trash There’s a last-resort method you can use: Delete Immediately. However, sometimes a file just doesn’t want to go, and you’ve done everything else. In Terminal, type lsof | grep -i followed by a space and part of the file name, and see if it shows what app or system component still has its hooks in. You can also use the Terminal command lsof, which tracks all files in use by even the lowest of low-level parts of the system.
