I'm interested in taking a look as macOS Mojave but am not willing to install it on my main production machine. However, I do not have another Mac to hand so have found myself upon this guide from Apple, walking you through the steps to install macOS Mojave on a seperate APFS volume on your normal Mac, easing many of the risks associated with running Beta software.
Whilst the guide makes it quite clear how to install Mojave on this new APFS volume, my question is: when I am done with macOS Mojave, how exactly would I remove this separate APFS volume and give it back to my normal installation of macOS High Sierra? Is this something easily done from Disk Utility or is is a slightly more complicated process involving the use of Terminal?
Thank you in advance for any help, Kind regards, Rocco
