everytime I run the command to create the bootable USB, I get the error: /Volumes/MyVolume is not a valid mount point. When I format the USB drive, using the Apple instructions, I chose 'MyVolume' as the name of the volume, so the name is correct. Why does this simple task need to be so freaking complicated. I've wasted hours and hours an hours already, trying to follow Apple's instructions to re-install the OS on my 2014 Mini after disk failure. I installed yosemite, but from that, I can't update to Monterey. So I am trying to install Sierra, which apparently can then be updated to Monterey, but that fails too. Apple, REALLY!!!! do you really have to make life **** for your customers!!!!
Lexs-Mac-mini:volumes Lex$ sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app
/Volumes/MyVolume is not a valid volume mount point.
and yet:
Lexs-Mac-mini:/ Lex$ cd volumes
Lexs-Mac-mini:volumes Lex$ ls

Lexs-Mac-mini:volumes Lex$
