Mac OSX Mavericks 10.9

creating a USB install disk is super easy now.

1. Download the Mavericks installer
2. it should be located /Applications/Install\ OS\ X\
3. Open up terminal and navigate into the Resources section of the app
/Applications/Install\ OS\ X\
4. Run the following command:
sudo ./createinstallmedia --volume /Volumes/ToFormat --applicationpath /Applications/Install\ OS\ X\

* notice that we named our volume “ToFormat”, you must insert the name of the volume you want to reformat.
** there are some other instructions on the internet, which require you to search for the base system.dmg, but the issue with that method is that it does not automatically create a recovery hd partition, so that features like file vault are not available.
