Sign out of your accounts
Once your files are backed up, it’s time to sign out of all your accounts. This includes iTunes(skip this step if using macOS Catalina or later), iCloud, and iMessage.
To sign out of iTunes, open the app and go to the “Account” menu. Account > Authorisations and then click “Deauthorise This Computer”
For iCloud, go to System Preferences > iCloud and click “Sign Out.”
To sign out of iMessage, go to Messages > Preferences and click “Sign Out.”
Use Disk Utility to erase your Mac
With your accounts all signed out, it’s time to erase your hard drive. To do this, we’ll use Disk Utility. First, restart your Mac and hold down the “Command” and “R” keys until you see the Apple logo. This will take you to the Recovery Mode menu. From there, select Disk Utility and click “Continue.”
In Disk Utility, select your hard drive from the left sidebar and then click the “Erase” button. From there, choose a name for your hard drive and make sure the “Format” is set to “Mac OS Extended (Journaled).” Then click “Erase” and wait for the process to finish.
Reset NVRAM and shut down
Once your hard drive has been erased, you’ll need to reset your NVRAM. This is important because it ensures that your Mac’s settings are reset and can help if you’re having trouble booting up after wiping your drive. To reset your NVRAM, shut down your Mac and then turn it back on while holding down the “Command,” “Option,” “P,” and “R” keys. Keep holding these keys until you hear the startup sound twice.
Finally, shut down your Mac and you’re all done! Wiping your hard drive might seem like a daunting task, but it’s actually pretty simple. Just make sure to back up your files, sign out of your accounts, and use Disk Utility to erase your drive. And if you run into any trouble, resetting your NVRAM can help.

This is important because it ensures that you won’t lose any data during the wiping process. Second, don’t skip any steps when signing out of your accounts.
