Unfortunately, today I wanted to update my operating system from Catalina to Big Sur. I had more than the approx. 12Gb required to installed (if I remember correctly I had around 21Gb available). Later, when only 2 minutes were left to finish the installation I had ´An error occurred preparing the software update - Big Sur´. This ended up in a loop after rebooting as described here: https://discussions.apple.com/thread/252038616
The problem is that apparently, the installation required way more than those 12G, so the only way I can think of getting out of this is to start in recovery mode, and use the terminal app to delete folders that I have in my desktop. Once this is done I hope the installation of Big Sur will work.
I am now in the terminal (bash 3.2) but I don´t know how to get to my desktop. After I type cd /Volumes I can see via ls that there are the files .fseventsd , Macintosh HD - Data , Macintosh HD and macOS Base System.
I assume that the files and folders in my desktop are in Macintosh HD - Data but I can´t access to it. I tried cd Macintosh HD - Data without result, the prompt out is ´cd: Macintosh: No such file or directory´.
I don´t know how to access the desktop and delete files from there.
