How to delete your Mac Hard Drive and delete Mac Partitions 2021

Are you running out of hard disk space and need to delete partitions on your Mac?
Are other guides you watched out of date? Welcome to the 2021 guide in how to delete your Mac Hard Drive and delete Mac Partitions.
In this video I show you how to make space on your mac by deleting partitions on it. I also show how to create partitions on your mac as well.
Furthermore I show how to delete your hard drive e.g wipe your mac hard drive clean as well. This will erase everything off your hard drive.

I use Mac OS tool; Disk Utility to complete these tasks

I am showing this video whilst running Mac OS Mojave on a Mac Pro 5,1. However this technique can be used on Catalina, Big Sur and on any supported iMac, Mac Mini, MacBook, MacBook Pro or MacBook Air.

I liked your video Matt because I appreciate and valued the information you shared in it, and you reminded me to hit the button at the right time, rather than asking before even giving any info. Good quality stuff Matt.

I’ve been trying to remove a part ion without success. I’ll give it another go now.
Do you have any advice on moving apps to an ssd but leave files on the existing hd.
Think about this where excel is on the ssd but my spreadsheet files and workbooks are on the normal Hd.
Thanks in advance.

I am trying to reinstall after deleting it previously for a new owner for my laptop. Now I want to install the OS. It keeps on giving me error saying "an error occurred when preparing the installation".

Changed the date and time still nothing.

So I am trying to start from the beginning by erasing everything again. APFS is greyed out. When I choose Mac OS extended journaled, it gives me an error.

I’ve just been given a 27 inch iMac, I need to wipe the 1tb hard drive, I’ve gone into recovery mode and utility but the erase it grey and doesn’t do anything, I carnt partition anything because that’s grey and the 1tb is full, I wanted to run legacy core patcher but the hard drive isn’t formatted correctly to do it, I’ve got two macs and a Mac book all running Ventura with no issues so I know how to install legacy core patcher. I don’t know how to wipe the hard drive

I upgraded from Big Sur to Mac Monterey and when I check storage, I have only a flash storage with 121 GB and only 5GB available!! Should I erase the 2 "untitled" drives? One is "Untitled" and the other is "Untitled Data" thanks!

Not workin!!! In Catalina 10.15.3 the minus button is disabled. After updating to Catalina, it have created "Macintosh HD" & "Macintosh HD" - data named partition. Can you help me to identify & remove unwanted partition from these ones??
