Making Bootable USB Flash Drive--Issues

[Icecoldak]

Hey guys Im trying to make a bootable USB disk so I can fresh install the new Mac Os. Im following the procedure outlined in the redmond pie article, but I keep getting this message "You must specify both the volume and install application path." Not sure what Im doing wrong and seems others are having the same problem. Thanks for any help.

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled —applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction &&say Done

Is your USB key named Untitled like in the article?

Yes it is, but Im not positive its a capital U. I didnt change a thing and Im pretty sure it came up as Untitled

Try it with a copy and paste of this. I notice in your command in post #1 the -- after Untitled is joined into a hyphen.

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

I had everything correct but I had an external hard drive also into a USB port so that was throwing it off. I disconnected my ext drive and everything went well!! thanks for help!
