How to Factory Reset a MacBook

If you are selling your MacBook, trading it in, or passing it down to a family member, you must completely wipe the hard drive. Simply dragging your files to the Trash icon is not enough. You must securely erase the cryptographic keys that protect your data, sever the computer’s connection to your Apple ID, and reinstall a fresh, clean version of macOS.

The method you use to factory reset your MacBook depends entirely on how old the computer is. Apple fundamentally changed the process when they released macOS Monterey.

Method 1: The “Erase Assistant” (For MacBooks 2018 or Newer)

If you are running macOS Monterey (or any newer version like Ventura or Sonoma) and your MacBook has an Apple Silicon chip (M1/M2/M3) or an Intel T2 Security Chip, the factory reset process is now identical to wiping an iPhone. It takes less than two minutes.

1. Click the Apple Logo in the top-left corner of the screen.
2. Select System Settings (or “System Preferences” on older versions).
3. Click on General in the left sidebar.
4. Click on Transfer or Reset on the right side of the screen.
5. Click the button that says Erase All Content and Settings.
6. A new window called the “Erase Assistant” will open. It will immediately demand your Administrator password. Enter it.
7. The assistant will warn you that this process will delete your Apple ID, Touch ID fingerprints, Bluetooth pairings, and Apple Wallet cards. Click Continue.
8. The Security Check: You will be prompted to enter your Apple ID password. This is critical. This step disables “Activation Lock.” If you skip this, the next owner will never be able to use the computer.
9. Click the final red button labeled Erase All Content & Settings.

The screen will go completely black, and the MacBook will reboot several times. When it finally stops on a screen that says “Hello” in multiple languages, the computer is fully wiped and ready to sell. You can hold down the power button to shut it off.

Method 2: Disk Utility Recovery Mode (For Older MacBooks)

If you are using an older Intel MacBook (from 2017 or earlier), it does not have the modern security chip required for the instant “Erase Assistant.” You must manually format the hard drive using macOS Recovery Mode.

Step 1: Manually Sign Out of Everything

Because the automated assistant isn’t here to do it for you, you must sever the connections manually to prevent locking the next owner out of the machine.

1. Open System Preferences.
2. Click on Apple ID.
3. Click Overview (or iCloud) on the left, and click Sign Out at the bottom right.
4. Open the Messages app. Click Messages in the top menu bar > Settings > iMessage > Sign Out.

Step 2: Format the Hard Drive

1. Click the Apple Logo and select Shut Down. Wait for the computer to turn completely off.
2. Press the Power Button to turn it back on, and immediately press and hold the Command (⌘) + R keys on your keyboard.
3. Hold the keys until you see the Apple logo or a spinning globe.
4. A “macOS Utilities” window will appear. Click on Disk Utility and click Continue.
5. Look at the sidebar on the left. Click on Macintosh HD (or whatever you named your primary hard drive).
6. Look at the toolbar at the top and click the Erase button (it has a minus symbol).
7. A prompt will appear. Ensure the Format is set to APFS (or Mac OS Extended (Journaled) if APFS isn’t available).
8. Click the red Erase button.

This completely nukes everything on the hard drive, including the operating system itself.

Step 3: Reinstall the Operating System

1. When the erase process is finished, close the Disk Utility window by clicking the red X in the top left corner.
2. You will return to the main macOS Utilities menu.
3. Click Reinstall macOS and click Continue.
4. Follow the prompts on the screen to download a fresh copy of the operating system from Apple’s servers. (You will need to connect to Wi-Fi in the top right corner of the screen).

When the installation completes and you see the Setup Assistant asking you to select your region, do not proceed. Press Command (⌘) + Q to shut down the Mac. It is now ready for the new owner.
