Hi @tcam

started this before I left today will follow up in the morning to let you know if it installed. Double Check your syntax

Hi @tcam

It looks like you have the spaces in the installer application path escaped AND quotes around the path, but it should only be one or the other!

@tcam to echo what @crigby said, either escape the path with backslashes, or use quotes, but not both.

/Applications/Install macOS Sierra.app/Contents/Resources/startosinstall --applicationpath "/Applications/Install macOS Sierra.app" --volume "/Volumes/Macintosh HD" --nointeraction

edit: a typo.
