Making a 10.9 Installer

There is now bundled with the 10.9 installer app a command line tool for creating the installation media. Browse to /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/ and you will notice a file called createinstallmedia. This is the command line tool needed to create the media and its basic output with no options is…

admin$ /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia

Usage: createinstallmedia –volume –applicationpath [–force]

Arguments–volume, A path to a volume that can be unmounted and erased to create the install media.

–applicationpath, A path to copy of the OS installer application to create the bootable media from.

–nointeraction, Erase the disk pointed to by volume without prompting for confirmation.

Example: createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X Mavericks.app

This tool must be run as root.

Great. So now I have partioned an external with a small 10Gb disk called installer. The name doesn’t really matter as after the tool creates the media the disk is renamed.

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Installer –applicationpath /Applications/Install\ OS\ X\ Mavericks.app

After a small wait I have a 10.9 USB installer I can take around in my pocket and complete my upgrades.
