Creating a Mavericks bootable install disk

So Apple released Mavericks yesterday, the 10th version of OS X.

Since Lion, Apple has done away with install media like DVDs and USB drives.

However, there are ways to make your own. This involves extracting the InstallESD.dmg file from the OS X install package and copying it to another disk.

If you have downloaded Mavericks you may have noticed that the InstallESD.dmg supplied is no longer bootable.

However all is not lost. Apple has supplied a way of making a new bootable disk via the command line.

Assuming you have downloaded the Mavericks installer application, run the following command in the terminal:

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

Now, just replace INSTALLDRIVE with the name of the disc you want to copy to.  The destination disk should be at least 8GB in size.

It will take a while but once it’s completed you should have a fully working bootable install disk.

If you are a bit wary of the command line, an easier way is to use a third party app called DiskMaker X.

This is a GUI tool that builds bootable drives for Lion, Mountain Lion and Mavericks. You can download it here.
