Erase Your Mac with Disk Utility: A Step-by-Step Guide

Are you looking to erase your Mac's hard drive? If so, this guide will walk you through the process using Disk Utility.

Before You Begin

Before you start, make sure you have backed up all your important files and data. Erasing your hard drive will permanently delete all content on it.

Starting Disk Utility

To open Disk Utility, restart your Mac and immediately hold down the power button until you see the startup options window. Select 'Disk Utility' from the Utilities window.

Erasing Your Hard Drive

Once you're in Disk Utility, select 'Macintosh HD' in the sidebar. Click on the Erase button in the toolbar, then enter the requested details:

* Name: Enter a name for your erased drive.

* Format: Choose APFS or Mac OS Extended (Journaled) as recommended by Disk Utility.

* Scheme: Select GUID Partition Map.

Confirming Erasure

Disk Utility will ask if you're sure you want to perform the restore function. Click 'Erase' to confirm.

Resolving Common Issues

If Disk Utility fails to erase your hard drive, it may be due to a damaged Partition Table on your Mac operating system. In this case, you can try running First Aid on the Mojave partition using macOS Recovery.

Using macOS Recovery

To start up from macOS Recovery:

1. Restart your Mac and immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.

2. Select your language and click 'Continue'.

3. In the Utilities window, select 'Disk Utility' and click 'Continue'.

Troubleshooting

If you're stuck in a boot loop after a failed update to Mavericks, you may need to erase your disk and set it up again.

Erasing your Mac's hard drive using Disk Utility is a relatively straightforward process. However, it's essential to make sure you've backed up all your important files and data before proceeding. If you encounter any issues during the erasure process, refer to Apple documentation for more technical information.
