A Comprehensive Guide to Wipe MacBook

Wiping your MacBook Pro/Air may seem daunting, but with the proper steps, it will become easy. With a few simple steps, you can guarantee all your sensitive data is erased from the device. Next, let’s dive in and explore how to wipe a MacBook Pro/Air effortlessly.

Step 1: Back Up Your Data for Future Use

Tip: If you have less personal data, you can also copy it directly to a USB drive. This will save you time.

Whether you plan to sell it or want to start over, erasing your MacBook is necessary. However, this process will delete all the information stored on it. If you have precious personal data in your MacBook, before you start, use Apple's built-in Time Machine application to back it up for future use. Here's a step-by-step guide:

  1. Plug the external storage device that holds the backup files into your Mac.
  2. Once your storage device is connected, go to "System Preferences" from the Apple menu in the top-left corner of your screen. Then, select "Time Machine."

  3. Click the "Select Backup Disk" button, choose your removable disk from the list, and click "Use Disk."

  4. Click "Options" and then the "-" button to remove files that do not need backing up.

  5. Click the clock icon in the top menu and select "Back Up Now."

Step 2: Sign Out of All Accounts

If you are giving away or selling your MacBook, you must log out of all accounts before wiping it for the following reasons:

Step 3: Clear Your Browser History and Cookies

Although Apple claims that the "Erase All Content and Settings" option will erase everything on your MacBook and restore it to its out-of-box condition. However, it may be beneficial to clear your browser history and cookies manually. Cookies save and store data you enter on a website, such as login information, which can pose a security risk if your MacBook Pro or Air falls into the wrong hands.

To clear them on Safari, you can follow these steps:

  1. Open the Safari application.
  2. Click "Safari > Clear History" in the top menu bar.

  3. Select "all history" and click "Clear History."

Step 4: Clears User Settings from Memory

Tip: If your MacBook is equipped with Apple silicon, please skip this step. If you're unsure, click here to find out about your MacBook Pro or Air.

On MacBooks equipped with Intel chips, the system uses NVRAM (Non-Volatile Random-Access Memory) to store specific settings, including display resolution, sound volume, startup-disk selection, time zone, and recent kernel panic information to speed up the operation. Therefore, we recommend resetting it before selling, giving away, or recycling. Here's how to do it:

  1. Restart your MacBook and immediately press and hold the "Option + Command + P + R" keys. You can release the keys after about 20 seconds, during which your device might appear to restart.
  2. Release the keys after the second startup sound.
  3. When the reboot is complete, NVRAM will be restored to its original state.
