Summary: Before you sell or donate your Mac and your macOS is macOS Monterey or later, you can use a built-in feature - Erase All Contents and Settings to securely wipe out sensitive data and reset your Mac to factory settings. Learn how to use Erase All Content and Settings on Mac.

The "Erase All Content and Settings" option is one of the new additions in macOS Monterey. Like the iPhone and iPad, the newest Mac operating system makes it simpler to return to factory settings. This feature requires macOS Monterey or later and a Mac with Apple silicon or the Apple T2 Security Chip.

When to Erase All Content and Settings?

You'll need to reset your Mac to factory settings in several scenarios. Here are several frequent reasons to wipe all files and settings:

  • You've decided to part with your Mac by selling it or donating it to someone else.
  • There is a significant malware infection.
  • Your goal is to start over.
  • Fix system errors.

You should clean your Mac of all data and preferences before handing it over to a new owner. If you don't, the new owners could obtain access to all of your personal information. Securely wiping the device in macOS erases all data but does not affect the operating system so that the Mac can be handed off without further preparation.

How do Erase Content and Settings work?

The Erase Assistant, commonly known as Erase All Content and Settings on Mac, is a potent feature. Mac users now have the option to completely wipe their gadgets and return them to their original state.

Using the Erase Assistant, you can quickly and easily remove your personal information and apps without worrying about losing your data. Erase All Content and Settings is only compatible with later versions of macOS.

Erase All Content and Settings on Mac

Unlike previous methods of erasing all data on a Mac, this new method does not necessitate reinstalling the OS afterward. In the process of erasing user data, macOS is not lost. Before the release of Monterey, every time a user deleted their data and preferences, they had to reinstall the operating system. You can now resell your Mac without extensive preparation or technical expertise.

Note: please note that the data on your Mac is not lost forever after erasing all content and settings, and the lost data can be recovered by data recovery software.

Erase All Content & Settings is very self-explanatory. To save you from reinstalling macOS, it deletes all user-installed programs and data and resets all preferences to their factory settings. Still, it does not delete the operating system itself.

Your Mac will be as good as new and ready for a clean install when it's done. This feature comes in handy when you want to ensure all your personal information has been wiped from an old computer before selling or donating it.
