Privacy matters, especially when you are about to resell or donate your old Mac or hard drive. You never know where it's going to end up. If the person who takes your device is a computer geek, chances are he can recover your private data — even if you've deleted them.

That's why you'll want to make sure none of your personal information is retrievable. Of course, the most reliable method is to destroy the device, but its value would become zero.

The best way to do this safely and economically is by using a Mac shredder or eraser application. We've got three great options for your choices.

Why do you need a Mac shredder software?

Let's start with the basics. When you drag a file or folder to the Trash and then delete it there, or you delete it from an external hard disk drive, the file isn't removed permanently at least for quite some time. What happens is your file or folder is simply erased from the file directory of your Mac or external HDD. By using a third-party Mac data recovery program, you can usually recover it provided that it is not overwritten — i.e. you haven't added new files to your Mac or the external drive.

To make that file unrecoverable, you can either keep saving new large items to that drive manually or use a third-party app to do so automatically. The former option can be quite time-consuming and it's often not secure because you can't tell whether the space contained in that file or folder is occupied or not, particularly if your hard drive has a large volume. That's why a Mac shredder utility comes into play.
