What to do before you sell, give away, trade in, or recycle your Mac - Apple Support

While it's possible to erase personal data without affecting the OS, it's generally recommended to perform a complete erase and reinstall of macOS for better security and a fresh start. Here's an overview of both approaches:

To erase personal details and data while preserving the OS:

1. Back up all important data to an external drive or cloud storage.

2. Sign out of all accounts (iCloud, app stores, etc.).

3. Use the built-in disk utility tool to erase free space on your drive, which securely removes deleted files.

However, it's strongly advised to perform a complete erase and reinstall of macOS instead. This approach is safer and ensures all personal data is removed:

1. Back up your data.

2. Restart your Mac and enter the recovery mode.

3. Use the disk utility tool to erase the entire drive.

4. Reinstall macOS from the recovery mode.

This method is preferable because:

1. It guarantees complete removal of all personal data.

2. It eliminates any potential malware or system issues.

3. It provides a fresh, clean installation of macOS.

4. It ensures no lingering files or settings remain from your use.

By performing a full erase and reinstall, you can be confident that your personal information is securely removed, and the MacBook is ready for its next user or a fresh start for yourself.

1. Go to » System Preferences
2. Click "Erase All Content and Settings"
3. Start the erase and wait until it displays the "Hello" screen
