Create Bootable macOS Sierra drive



You’ll need the following

  1. USB drive 8GB+
  2. macOS Sierra

The easy way to create a bootable macOS drive is by executing the following command.  This assumes your USB drive is named USBDrive and your macOS Sierra installer is in the Applications folder.  Change if needed.

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

It’ll ask you for confirmation and then proceed to wipe the USB drive and put macOS on it.  Do note that it will erase the contents of the drive, so make sure you don’t have anything important on it.

Non interactive

You can add the option “–nointeraction” to have it not ask for confirmation.

Example :

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