How to permanently erase data in macOS Big Sur? Deleting data from Mac OS is one of those steps that may be difficult for several reasons. One of them is because Mac OS has a fairly strict system that makes it difficult for users to permanently delete data.

If you are in the midst of permanently deleting data from Mac OS Big Sur system for some reason, such as wanting to sell your MacBook, then there are a number of steps you can take. One of the recommended methods is to use a macOS Big Sur data erasure tool - DoYourData Super Eraser for Mac. We'll see why this method is so safe and easy. But before that, let's cover the conventional method if you want to try it.

1. Format and Quick Format SSD under macOS Big Sur

You can use the conventional method, namely by using the SSD Format and Quick Format features on the Mac. The way to do this is as follows.

• Open Disk Utility, this is the built-in software from Mac OS which is commonly used to completely erase data without leaving any residue.
• After the software opens, please click on the Erase menu at the top. This menu will sweep all the contents of a folder or Drive that you select.
• Done.

This method has weaknesses. First, Disk Utility cannot format a drive containing a file system. So if you want to format the whole disk, you can't go this way. Second, Disk Utility does not permanently delete data. Even though it looks permanent, you can still recover data using Mac Data Recovery App. So, this method is not safe.
