Create a bootable OSX / MacOS Mavericks on a USB stick / thumb drive
This way worked for me…
- Download the Installer from the App Store. You end up with a file called “Install OS X Mavericks.app” (5.34Gb) in your Applications folder (and the Install OSX application open)
- Format a USB drive. Use Disk Utility. Partition tab, 1 partition, options… GUID. Call it “Untitled”. Here's the bit… Check the mount point at the bottom of the screen! (Does it say /Volumes/Untitled?)
- Don't eject / unmount it.
- Open Terminal. Run the following command…<br />

If the mount point was /Volumes/Untitled then this command will work. If it was anything else, you will get an error. Change the name of the “–volume” attribute to what you saw as the mount point.<br /> If all goes well, be prepared to make a cup of tea and take your time drinking it…
