Quick Answer

To factory reset a MacBook, back up your files, sign out of important accounts, use Erase All Content and Settings if available, or start macOS Recovery, erase the internal drive, reinstall macOS, and confirm the setup screen appears.

What You Need

  • MacBook and charger
  • Reliable internet connection
  • Admin password
  • Apple ID password
  • Backup drive or cloud backup
  • Time to reinstall macOS

Safety Precautions

  • Back up important files before erasing.
  • Know your Apple ID password before starting.
  • Sign out of accounts if selling or giving away the MacBook.
  • Keep the MacBook plugged in during reset.
  • Use Apple instructions for your chip type and macOS version if screens differ.

Step-by-Step Instructions

  1. Step 1

    Back up your MacBook

    Use Time Machine, cloud storage, or another backup method for files you need.

  2. Step 2

    Check for Erase All Content and Settings

    On supported macOS versions, use System Settings to erase data more simply.

  3. Step 3

    Sign out if transferring ownership

    Sign out of Apple ID, Messages, and other accounts as needed.

  4. Step 4

    Start recovery if needed

    Use macOS Recovery when Erase All Content and Settings is not available.

  5. Step 5

    Erase the internal drive

    In Disk Utility, choose the correct internal drive and erase it using the recommended format.

  6. Step 6

    Reinstall macOS

    Return to recovery tools and choose Reinstall macOS.

  7. Step 7

    Stop at setup screen

    If selling the MacBook, leave it at the welcome/setup screen for the next owner.

Practical Example

Example: Before selling your MacBook, you make a Time Machine backup, sign out of Apple ID, use Erase All Content and Settings, and stop when the setup assistant appears.

Common Mistakes

  • Starting without a backup
  • Forgetting Apple ID password
  • Erasing the wrong drive
  • Letting the battery die during reinstall
  • Setting up the Mac again before selling it
  • Ignoring Activation Lock or device management

Troubleshooting

Erase All Content and Settings is missing

Your Mac or macOS version may not support it; use macOS Recovery instead.

Recovery asks for Apple ID

Use the Apple ID linked to the MacBook or follow Apple account recovery.

Reinstall fails

Check internet, plug in power, restart recovery, and try again.

Mac is managed by work or school

Contact the organization before erasing or transferring it.
