Instructions for performing a factory reset on a MacBook with Big Sur

Performing a factory reset on a MacBook running macOS Big Sur involves a few steps to ensure all your data is securely wiped. Here’s a detailed guide to help you through the process:

Step 1: Backup Your Data Before initiating a factory reset, it’s crucial to back up all your important files. You can use Apple’s built-in Time Machine feature or manually copy your files to an external drive or cloud storage.

Step 2: Sign Out of Your Accounts Deauthorize your Mac from any services like iTunes, iCloud, and iMessage. Open these apps, go to their respective settings, and sign out. This helps prevent any future complications with your accounts.

Step 4: Restart in Recovery Mode Restart your Mac and hold down Command + R ( ⌘ + R ) until the Apple logo appears. This will boot your Mac into Recovery Mode.

Step 5: Erase the Disk In Recovery Mode, open Disk Utility. Select your main drive (usually named “Macintosh HD” or similar) from the list on the left. Click on “Erase” and follow the prompts. Choose “Mac OS Extended (Journaled)” as the format, and give it a name. Click “Erase” to begin the process.

Step 6: Reinstall macOS Big Sur After erasing the disk, close Disk Utility. Choose “Reinstall macOS” from the Utilities menu. Follow the prompts to reinstall the operating system. This process will take some time, as it involves downloading the necessary files from Apple’s servers.

Step 7: Set Up Your Mac Once the installation is complete, your Mac will restart. Follow the on-screen instructions to set up your MacBook like you did when you first bought it.

Remember, performing a factory reset will permanently erase all data from your Mac. Double-check your backups and make sure you have everything you need before proceeding.

2. Selecting the Disk for Erasure: Inside Disk Utility, you’ll see a list of all connected storage devices. Locate and select the disk you wish to erase from the left-hand pane. Be extremely cautious at this step, as erasing a disk will permanently delete all data. Once the disk is selected, click on the Erase button in the menu bar. A new window will appear, prompting you to confirm the erase process. Here, you can also provide a new name for the disk if desired. After reviewing your choices, click the “Erase” button to initiate the process. Disk Utility will now proceed to erase the selected disk, giving you a clean slate to work with.
