After Erasing Macintosh HD: A Step-by-Step Guide

When dealing with issues related to disk volumes on your Mac, it's essential to ensure that your data is safe and remove any redundant volumes properly. This article will walk you through the process of erasing a Macintosh HD volume using macOS Recovery.

To access macOS Recovery, follow these steps:

1. Select a volume, such as Macintosh HD from the sidebar, then click the First Aid button.

2. Click on View and select Show All Devices.

3. Select Disk Utility and click Continue.

4. After startup is complete, the macOS Utilities menu should appear.

Alternatively, if you are unable to boot into Recovery mode, you can try Internet Recovery by pressing and holding Option, Command (⌘), and R after turning on your Mac. Release the keys when the Apple logo appears.

Once in Recovery mode, follow these steps:

1. If prompted, enter your password for a user with admin status.

2. Turn on your Mac and immediately press and hold down two keys: Command (⌘) and R.

3. Shutdown your Mac by going to the Apple menu and selecting Shut Down.

Before erasing any disk volumes, it's crucial to have a recent backup of your Mac using Time Machine. If you're experiencing issues with one of your disk volumes, checking for errors using Disk Utility is a good starting point.

However, if you've determined that removing a redundant volume is necessary, follow these steps:

1. Identify the duplicate volumes and determine which ones are unnecessary.

2. Use macOS Recovery to erase the unwanted volume(s).

Remember to always make sure you have a recent backup of your Mac before deleting any disk volumes. For more information on backing up your Mac, see our article on How to Back Up Your Mac with Time Machine.
