Hello guys,
I'm trying to make a bootable USB with Sierra. It's using the "GUID partition map", and is formatted to "Mac OS Extended (Journaled)" with the name "MyVolume". The "Install MacOS Sierra" is in my applications folder and I'm entering this command into terminal;

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app

No matter what the message "/Volumes/MyVolume is not a valid volume mount point." comes up.
I have no clue where I'm going wrong, any help is massively appreciated!
