Steps to Delete Files from Your Mac and Restore It to New Condition

Deleting unwanted files and restoring your Mac to a clean, factory-like setup can help optimize performance, free up storage, and enhance your user experience. This guide will walk you through the necessary steps to delete your files, encode your startup disk using FileVault, and restore your Mac to its default factory setting.

What to Do Before Selling, Giving Away, or Trading in Your Mac

Before you consider selling, giving away, or trading in your Mac, it's essential to take a few crucial steps to ensure your personal data is protected. Here’s what you need to do:

Transfer Any Data You Want to Keep

Start with transferring all the files, photos, documents, and videos that you want to retain off your Mac. You can use cloud storage services, external hard drives, or USB drives. Ensure you have backups to prevent loss of important information.

Starting the macOS Restoration Process

Once you have transferred all your necessary data, you can proceed to restore your Mac to its factory default settings. The process can vary depending on whether you have a hard disc or an SSD, as well as whether you have previously enabled FileVault.

Turning on FileVault

If you haven't enabled FileVault, doing so now is recommended. FileVault encrypts your startup disk, providing an additional layer of security for your data.

Note: This process can take several hours to complete, but you can still use your Mac while it runs in the background.

Using Disk Utility to Erase the Disk and Reinstall macOS

Once the disk is encrypted, you need to boot into Recovery Mode and use Disk Utility to erase the disk and then reinstall macOS.

Booting into Recovery Mode:

1. Restart your Mac and hold down the Command (?) R keys until you see the macOS Recovery screen.

2. Once in Recovery Mode, open Disk Utility and select your startup disk.

3. Erase the disk and reinstall macOS: - Click the Erase button. - In the "Security" drop-down menu, select the highest security option. (For macOS Big Sur and later, you can use the Secure Erase feature under Disk Utilities.) - Click Erase again to confirm the action.

4. After erasing the disk, you can choose to install the latest version of macOS from the App Store.

Using macOS Recovery for Older Machines

If your Mac has an older OS, it may not support FileVault. In such cases, you may need to use a secure erase method that can work with hard discs but is not recommended for SSDs. You can use third-party tools like Recovery Requester to perform a multi-pass secure erase on your SSD.
