How to Factory Reset a Mac Before Selling or Handing It Off

Before you sell, donate, or recycle your Mac, it’s crucial to erase all your data securely and restore the system to factory settings. Macs store sensitive personal data, from Apple ID credentials to documents and photos. A full reset ensures your privacy is protected and prepares the device for a new user. Depending on your Mac model and macOS version, the reset process can vary, but this guide walks you through each method clearly.

For Macs with Apple Silicon (M1, M2, M3) or T2 Chip Running macOS Monterey or Later

If your Mac uses Apple silicon or has an Apple T2 Security Chip and is running macOS Monterey (version 12) or later, the process is fast and automated using Erase Assistant.

Steps:

1- Click the Apple menu  > System Settings (or System Preferences in Monterey).

2- Navigate to General > Transfer or Reset.

3- Click Erase All Content and Settings.

4- Enter your administrator password when prompted.

5- Review the summary showing what will be erased: user accounts, apps, settings, and Apple services.

6- Follow the prompts to sign out of Apple ID, Find My Mac, iCloud, and iMessage.

7- Confirm to proceed. The Mac will erase all content, restart, and display the setup screen.

8- To leave it ready for the next user, press Command + Q and shut it down.

Note: If you’re trading in or recycling your Mac, this step is sufficient to ensure the system is clean and secure.
