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 Are other guides you watched out of date?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.
