Erasing all content and settings on a Mac is a significant process that should be undertaken with caution, as it will completely wipe out all data, applications, and customizations. This process is often necessary when selling, giving away, or recycling a Mac, to ensure that personal and sensitive information does not fall into the wrong hands. In this article, we will guide you through the steps to completely erase all content and settings on a Mac, ensuring that your device is restored to its factory settings.
Preparation is Key
Before you start the process of erasing all content and settings, it is essential to prepare your Mac.
