This article tells you how to format the startup disk (built-in) of the M2 Mac with Apple Silicon M2 chip and show the right method to permanently erase data on a M2 Mac.

Back up your Data before erasing your M2 Mac

Before doing anything, you should look to back up your Mac files. You can do it by copying the files from Mac to an external drive. However, if you're using iCloud, your contacts, mail, photos, and documents should automatically be backed up in your cloud storage.

But, we recommend you back up the Mac files through Time Machine. In this way, you'll be able to transfer the backed-up files to a new Mac as Time Machine is a built-in tool of Mac that performs better than any other tool.

You also can try disk cloning software - such as DoYourClone for Mac to help you create a bootable clone backup for your M2 Mac.

Unlink Your Apps

You'll need to unlink some apps manually before saying goodbye to your M2 Mac. Some third-party apps need a license to work on any computer, so you need to consider the license you might have purchased.

Similarly, it is recommended to de-authorize the iTunes account from the device as it helps remove its access to the content you purchased from the App Store, iBook Store, and iTunes Store, including books and apps and TV shows, movies, and music.
