During the latest update, I was stuck in a boot loop. It was saying there was not enough space.
Then I tried to boot from the Macintosh HD but it was always stuck after pressing Restart.
After that I did a forced shutdown and want to reinstall MacOS Catalina but cannot as it is showing I don't have enough space.
So, I want to format/re-partition and install but there are 2 APFS volumes now, "Macintosh HD" & "Macintosh HD - Data". What is the best way to do this without further messing up?
