    I was asked to build this. I could have sworn it used to be done the same way, but whatever. Here you go:

    1. Show hidden files by opening /Applications/Utilities/Terminal.app and typing the following:
    2. Right click Installer.app file and click Show Package Contents, Open Contents folder, then look in SharedSupport folder. You will see InstallESD.dmg.
    3. Mount InstallESD.dmg.
    4. Copy the BaseSystem.dmg file out to somewhere convenient.
    5. Do not mount BaseSystem.dmg. Just open Disk Utility and restore it to a flash drive.
    6. When that's done look in the flash drive you just restored to and go to /System/Installation/. In that folder you will see a white icon with an arrow called Packages. That's a broken alias. Delete it.
    7. Now go back to your InstallESD.dmg file. Inside is a folder weighing in at about 4.5GB called Packages. Copy that folder onto the flash drive in place of where the alias was.
    8. Go ahead and hide the hidden folders again by going back to the Terminal and typing:
    9. Done. Boot from the flash drive and get to work.

    As per usual, don't blame me if you screw up. If you somehow need these instructions simpler don't be afraid to ask. Lots of smart people around here.

    Awesome! Still no solution on the Developer Forum. You just saved me a bunch of time on a clean installation. Thanks so much.

    Did you use an SD card or a USB Thumb drive? Also what size do you recommend? It sounds like 8GB is needed, but I wonder if it would be better to get 16GB to allow for future growth.

    Either one will work. 8GB is plenty.

    Leopard Installer: 8GB
    Snow Leopard Installer: 7.5GB
    Lion Installer: 5GB
    Mountain Lion Installer: 5.5GB
    Mavericks DP1 Installer: 6GB

    I have a 64GB flash drive with every OS X Installer from Leopard to now on it. Each time a new OS comes out I make another 8GB partition on it.

    I don't see "BaseSystem.dmg" anywhere. The only files inside OSX Install.dmg are

    BaseSystemBinaries.pkg
    BaseSystemResources.pkg

    I am currently copying Restore - "OSX Install ESD" to my USB drive. Lets see if that works.

    Edit: That did not work.

    Found the solution.

    To see BaseSysemt.dmg, you need to

    1. Open terminal

    2. Enter "defaults write com.apple.Finder AppleShowAllFiles YES"

    3. Hold Alt keyboard button and click on Finder - choose rellaunch finder.

    4. You will then see hidden files and BaseSysemt.dmg

    Worked for me. Make sure to Relaunch Finder after that and re-open the package content

    This method does not create a recovery partition.

    Does anyone know how to make a bootable drive that will install Mavericks AND a recovery partition?

    I have the beta dmg file. I want to upgrade my 10.8 install to the beta without losing data. Is that possible or only a clean install?

    You can upgrade without losing any data.




    For me it appears as if

    defaults write com.apple.finder AppleShowAllFiles FALSE
    and
    defaults write com.apple.finder AppleShowAllFiles TRUE

    take effect without restarting finder (you do have to refresh the window though, going to a new folder and back for example)

    Circle With Slash

    I am able to build a bootable usb drive. It boots, I get the apple logo, and then eventually I get a circle with a slash.

    Anybody else run into this.

    Regards,

    Chris

    I've followed your guide, and it's worked great to create the bootable USB but I'm currently having some problems with the installation. I get to the point where I choose what disk i'm going to install to, and then it just comes up with "Signing into the App Store" which I've provided an image of below. Any ideas?

    Can you upload a screenshot of a Finder window that shows the file structure of your usb installer in list mode?

    This is not what the file structure should look like, but this is an example of the screenshot I need to see. http://forums.macrumors.com/showpost.php?p=17390685&postcount=113

    Mine never did that. I have no idea why it would.
