Creating OS X Mavericks Install Media

mavericksIT staff, and even consumers often want to have a physical bootable install disk for OS X.  In OS X Mavericks, Apple have provided a relatively simple command line tool for creating bootable install media.

To create the install media, mount a volume that you would like to use as an install disk.  This volume needs to be able to hold at least 5.36 GB of data to house the install media. Note that this volume will be erased and reconfigured as an OS X installer. With the desired volume mounted, open the Terminal application and execute the following command:

sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/TargetVolumeName --applicationpath /Applications/Install OS X Mavericks.app --nointeraction

Replace “TargetVolumeName” with the name of the volume you want to turn into a bootable OS X Mavericks installation disk.

See the screenshot below for the Terminal output from the command above.
