How to Erase and Reset Your Mac Before You Sell It

Before you say goodbye to your old Mac and prepare to upgrade or sell it, take a moment to back up everything using Time Machine for a whole system backup. Then, use Migration Assistant to transfer files, settings, and other personal data to your new Mac. Finally, erase all content on the old device by signing out of Apple accounts and deleting personal information, ensuring your next owner won’t have access to sensitive data you want to protect. This process helps keep your digital traces safe while you welcome your new machine.
