    Hey guys,

    So I am currently running Mavericks 10.9.3, and I want to make an bootable USB installer so I can reformat my hard drive and do a fresh install of the OS

    I have an 8GB Ativa USB, which I formatted following this guide

    I set it to 1 Partition, GUID Partition Table, Extended (Journaled), and renamed it "Untitled"

    Then, using this guide

    I copied the terminal code in terminal to mount the Mavericks installer (which I just downloaded from the Mac Store), only to get a "/Volumes/Untitled is not a valid volume mount point" error.

    Note: I have administrator controls on this computer.

    Here are a couple of pictures to prove that I did everything right




    Can anyone help me with this?

    The following is real easy for me. Others may weigh in later ..

    Have Mavericks downloaded to the desktop from App Store. It may take a while. Leave it there, and do not touch it. I tried your way but for some reason the process stopped and gave me an error stating that Mavericks could not be found....So

    1. Plug in your USB drive and open Disk Utility.

    2. Select the USB drive in the sidebar and click on the Erase tab.

    3. Select Mac OS Extended (Journaled) in the Format box and name it Untitled.

    4. Click Erase, and wait for the format to finish.

    5. When it’s done, close Disk Utility and open Terminal. Type in correctly or copy and paste the following command and press Enter:

    sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction

    This command will officially make the USB boot drive, and it’ll take about 20 minutes.

    While it’s doing its thing, don’t mess with Terminal or eject the flash drive.

    Once done, it’ll say Copy complete. Finnished.


    After hitting enter with the above command, it will ask for your passcode. Enter that and press Enter. (Be advised, when you start to type in your Apple ID passcode into the terminal, you will NOT see it being entered. This is normal. Just enter it correctly)

    Or you can download this program to make a USB installer..

    I can save you some time - you probably don't need the USB installer, unless you're physically replacing the hard drive. Your Mac has a Recovery Partition already on it, that you can use to fully erase & reinstall OS X onto the primary partition.
