Dec 31, 2013 6:35 PM in response to lkvillaby davidnave,that's irritating. You have the correct command, but does it do the same thing if you do --applicationpath /applications/install os\ x\ Mavericks.app ? do you get the same error if you erase or repartition the drive manually?
diskutil eraseDisk JHFS+ Untitled disk1, where disk1 is the mount point for the removable media.
You can get the path, diskutil list and you'll get a list with /dev/disk0, /dev/disk1, etc.

Dec 31, 2013 7:23 PM in response to lkvillaby Linc Davis,The command doesn't work in 10.6. Make a copy of the installer application, then run it. Once 10.9 is installed, move the copy back into the Applications folder and run the command again.

May 5, 2014 8:03 PM in response to Linc Davisby Mac-Guyver,1) When you say, "make a copy then run it," a) why not run the original? b) where? I don't have another 5 GB of space on my internal drive
2) What do you mean "Once 10.9 is installed?" Where do you want me to install 10.9 to?
3) When you say, "move the copy back into the Applications folder," do you mean replace the original?
4) What does this accomplish? How does it prevent the 9999 error?

May 5, 2014 8:25 PM in response to Mac-Guyverby davidnave,1. If you leave the installer in the /Applications folder, the OS will delete the installer at the end of the install automatically.
2. The USB installer can only be created from a computer running 10.9. If you run the command in any OS earlier than 10.9, you will get the 9999 error. Not the most useful tool in the world, I admit.
3. Again, I think Linc was just trying to avoid having to provide a different path for the command. The way the article written, it presumes the Installer is in the /Applicaitons folder.
Hope that helps.

May 6, 2014 3:44 PM in response to davidnaveby Mac-Guyver,Oh,
createinstallmediaonly runs on OS 10.9! Oh! The 9999 is if you try to run it on an earlier OS! Oh! Linc means to update the current drive to Mavericks, and then one will be able to runcreateinstallmedia, if one has first saved away a copy of the installer.But if, like me, you are trying to create an installer to do a clean install on an empty drive, without replacing the earlier OS on your current drive, then...
You must use the slightly more complicated instructions you can find all over the place that look like
- Right click "Install OS X Mavericks.app" and show package contents
- Find a certain .dmg file and double click
- Find a hidden .dmg within the drive that mounts from the first .dmg
- Double-click or use "mount" on the hidden .dmg within the .dmg
- Use Disk Utility to "restore" the second disk image onto the erased USB drive
- Then replace an alias folder with a copy of a huge folder within the first disk image
I had success with the "Option 2: Use Disk Utility" section here.
