Are you looking to erase your Mac computer? Whether you’re selling your computer, giving it away, or simply starting fresh, it’s important to properly wipe all of your personal data from the device. In this tutorial, we will guide you through the steps to erase a Mac and ensure that your information stays private.

Before You Begin

Before you start erasing your Mac, make sure to:

  • Back up your data: Before wiping your computer clean, it’s essential to back up all of your important files and documents. You can use Time Machine or manually transfer your data to an external storage device.
  • Sign out of iCloud: To prevent any issues with activation lock or Find My Mac, sign out of iCloud on your Mac.

    Go to System Preferences > Apple ID and click on the “Overview” tab. Then click on “Sign Out”.

Erase Your Mac Using Recovery Mode

To completely erase your Mac computer, follow these steps:

Step 1: Restart Your Mac in Recovery Mode

To enter recovery mode, press and hold the Command + R keys immediately after restarting your Mac. Continue holding until the Apple logo or a spinning globe appears.

Step 2: Erase the Startup Disk

  1. In recovery mode, select “Disk Utility” and click “Continue”.
  2. In Disk Utility, select your startup disk (usually named “Macintosh HD”) from the sidebar.
  3. Click on the “Erase” button at the top of the window.
  4. A pop-up window will appear. Choose a name for your disk and select the desired format (usually “Mac OS Extended (Journaled)”).
  5. Click on the “Erase” button to begin the erasing process.
  6. Once the process is complete, close Disk Utility.

Step 3: Reinstall macOS

  1. In recovery mode, select “Reinstall macOS” and click “Continue”.
  2. Follow the on-screen instructions to reinstall macOS on your newly erased startup disk.
  3. Once the reinstallation is complete, your Mac will restart with a fresh copy of macOS.

Final Thoughts

Congratulations! You have successfully erased your Mac computer.

Remember to set up your Mac with a new user account and restore your backed-up data if needed. By following these steps, you can ensure that your personal information remains secure when parting ways with your Mac.

Note: It’s important to note that erasing a Mac permanently deletes all data from the hard drive. Make sure you have backed up everything you need before proceeding with these steps.
