Factory resetting a Mac is a big decision since it erases all your files. So, it's important to fully understand what happens if you reset a Mac to factory settings.

How to factory reset a Mac

In detail, Mac factory resetting involves three parts:

  • 1. Back up your files on Mac hard drive
  • 2. Erase Mac hard drive

What You Should Know About Factory Resetting Mac:

Resetting a device can be very beneficial and useful in the following situations:

  • Repair of a malfunctioning device with software problems and operating system errors.
  • Removal of a virus or a file which is very hard to remove.
  • Clearing storage space on computer hard drives or memories of other digital devices.
  • Removal of all user data on the device before selling, donating, giving away or trading in it.
  • Removal of all user data on the second-hand device before you become the new user.

But before taking advantage of device resetting, most people get stuck in a problem: "Should I do a hard reset or a factory reset?"

Factory Reset VS. Hard Reset

You may have heard of factory reset and hard reset and want to if they have any difference. Actutally, the factory reset, hard reset, hardware reset, and master reset, literally mean the similar thing.

But for some electronic devices like laptop and desktop computers, Android phones, iPhones and tablets, factory reset is an option on your device while a hard reset is a physical button accomplished by a combination of power, volume, home or other buttons.

Either a factory reset or hard reset will restore the device to the state when it left the factory and delete all your personal data on it.

What about resetting a Mac?

There is no physical hard reset buttons on Mac. To reset MacBook Pro and any other Macs, you need to reformat the startup disk and then reinstall macOS on the Mac.

It means all data on the startup will be deleted and wiped out, including email accounts, apps, contacts, personal files, third-party programs, all preferences and user data associated with the operating system.

Therefore, think twice before you are going to perform a factory reset because you can't undo it once factory reset is done.
