Every time a new OS is released I always see dozens of questions about how to create bootable USB disks with the new OS in the fastest way possible. As such, here is the fastest way I have found – it will install a fully functional Mavericks system on a USB 3.0 (or Thunderbolt) drive in less than 5 minutes (disclaimer: may take up to 20 minutes with USB 2.0).
- Download Mavericks from the App Store (it’s free!)
- Connect your USB 3.0 drive (≥8GB)
- Use Disk Utility to erase the drive (Mac OS X Extended, Journaled), and name it Untitled
- Run this command from Terminal.app:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
That’s it! You should have a fully bootable Mavericks USB drive (or installer) in about 5 minutes.
