Whether you want to sell your computer, give it away, or simply fix some issues, resetting your Mac can be a great solution. In this article, we will show you how to reset your Mac to its factory settings or wipe out your personal data, step by step. Let’s get started!

Part 1: Resetting Your Mac to Factory Settings

If you want to reset your Mac to its factory settings, you will erase all the data and settings on your computer and restore it to its original state. This process is also known as a ‘factory reset’. This is a good option if you want to sell your Mac or if you want to start fresh without any previous data or settings. Here are the steps:

  1. Back up your data: Before resetting your Mac, make sure to back up your important files and documents. You can use an external hard drive, iCloud, or any other reliable backup method.
  2. Sign out of everything: Make sure to sign out of all your accounts and services, such as iCloud, iTunes, iMessage, and FaceTime. You can do this by going to System Preferences > iCloud (or any other service) and clicking on ‘Sign Out’.
  3. Restart your Mac: Click on the Apple menu and select ‘Restart’.
  4. Enter recovery mode: As your Mac restarts, press and hold the Command + R keys until the Apple logo appears. This will enter you into recovery mode.
  5. Erase your Mac: In recovery mode, select ‘Disk Utility’ and click on ‘Continue’. Then, select your disk and click on ‘Erase’. Choose a name and format for your disk and click on ‘Erase’ again. This will erase all the data on your Mac.
  6. Reinstall macOS: After erasing your Mac, go back to the main menu in recovery mode and select ‘Reinstall macOS’. Follow the instructions on the screen to complete the reinstallation process.
  7. Set up your Mac: Once the reinstallation process is complete, you can set up your Mac as a new computer. You can choose your language, location, and other settings.

Part 2: Erasing Your Personal Data

If you want to keep your Mac but erase all your personal data, you can do so by using the built-in macOS feature called ‘Erase Mac’. This is a good option if you want to keep your Mac, but with a clean slate. Here’s how:

  1. Back up your data: Before erasing your personal data, make sure to back up your important files and documents. You can use an external hard drive, iCloud, or any other reliable backup method.
  2. Sign out of everything: Make sure to sign out of all your accounts and services, such as iCloud, iTunes, iMessage, and FaceTime. You can do this by going to System Preferences > iCloud (or any other service) and clicking on ‘Sign Out’.
  3. Enable FileVault: FileVault is a built-in encryption feature that protects your data. Make sure to enable FileVault before erasing your personal data. You can do this by going to System Preferences > Security & Privacy > FileVault and clicking on ‘Turn On FileVault’.
  4. Erase your personal data: Go to System Preferences > Security & Privacy > General and click on ‘Set Password’. Then, restart your Mac and hold down Command + R until the Apple logo appears. This will enter you into recovery mode. In recovery mode, select ‘Disk Utility’ and click on ‘Continue’. Then, select your disk and click on ‘Erase’. Choose a name and format for your disk and click on ‘Erase’ again. This will erase all your personal data.
  5. Disable FileVault: After erasing your personal data, disable FileVault by going to System Preferences > Security & Privacy > FileVault and clicking on ‘Turn Off FileVault’.

Resetting vs. Erasing: What’s the Difference?

You might be wondering what’s the difference between resetting your Mac and erasing your personal data. The main difference is that resetting your Mac will erase all the data and settings on your computer and restore it to its original state, as if you just bought it from the store. Erasing your personal data, on the other hand, will keep your Mac’s original settings and only erase your personal data, such as your files, photos, and documents. Both options are useful depending on your needs.
