On Monday Apple finally unveiled to the world the next iteration of OS X, Mavericks. A developer preview of the new operating system is available now as a Mac App Store download for registered developers. Delivering Mavericks via a download is super conveient and easy for everyday users but can be unhelpful in several troubleshooting or advanced OS modification situations. The only way to obtain a bootable OS X Mavericks USB flash drive is to create your own:

The Marek Bell blog notes that creating a bootable flash drive of Mavericks is a bit more intricate than Mountain Lion because “it is no longer possible to simply restore the InstallESD.dmg to get a bootable image for USB / Flash drive installation.” But there is a way around this obstacle, which Marek outlines in his thorough walkthrough of creating a bootable OS X Mavericks flash drive. You will need at least a 8GB Flash Drive (USB 3.0 is obviously a better choice).

May 10, 2005  I am a Linux user and can burn bootable CD's from image files all day long, but this is just killing me and getting rather expensive. I have made sure to mount the dmg file for each of the 4 disks, tried just burning a data cd, then burned to an image and burned the image to cd, tried a mac volume, nothing seems to work.

1. You are going to need to see some hidden files for this. So start by opening Terminal.app and pasting in the following (don’t worry, we’ll undo this change when we are done)…defaults write com.apple.Finder AppleShowAllFiles YESkillall Finder
2. Download the installer as normal from the app store. (At time of writing this is only possible for those with access to the developer previews).
3. After download you will have the ‘Install OS X 10.9′ app in your /Applications folder. Right-click it and select ‘Show Package Contents’.
4. Navigate to the Contents/SharedSupport. There you will see the InstallESD.dmg file. Unfortunately, you can’t just grab it and restore it. Instead double-click it to mount it.
5. You should now see the normally hidden BaseSystem.dmg file in the mounted volume.
6. Open Disk Utility and restore the source BaseSystem.dmg to the destination of your USB drive.
7. Now open up the restored USB volume (default name is OS X Base System) and navigate to System/Installation. In there you will see an alias for Packages. Delete this alias.
8. Copy the full Packages folder from the root of the mounted InstallESD volume (the same place you got the BaseSystem.dmg file) to the USB volumes System/Installation folder. Basically, replace the Packages alias you just deleted with the real Packages folder from the original InstallESD volume.
9. The USB drive should now be bootable. So simply restart, hold down the Option key (Alt) when booting with the USB drive in your machine, and you should get the option to boot from the USB drive.
10. Remember, to rehide the normall hidden files just repeat step 1 but change YES to NO.

Once done, you will notice a new drive name will be displayed on the left side, the name that you given in the partition information. Now close the Disk Utility tool.

Show hidden files

Showing hidden files is required, because there are few hidden files in the OS X Yosemite installer package that you need to unhide first to write them on bootable USB drive.

Open Mac “Terminal” command line: press cmd+space keys and type Terminal in the spotlight, click the Terminal from search results or just open the Terminal from Applications > Utilities > Terminal.

Type the following two commands one by one:

defaults write com.apple.finder AppleShowAllFiles YES

Killall Finder

First command is going to show hidden files and the second one is to restart the Finder so we can see the instant effect of first command. Close the Terminal.

Open Applications, here you will see your downloaded OS X Yosemite file “Install OS X 10.10”. Cmd+click on it to view the menu, select “Show Package Contents”.

Open “Contents” > “SharedSupport” folder and here you will see “InstallESD.dmg” file, double click to open the file and OS X may starts verifying this file so let the verification process finished.

After that you will see a folder with the following content in it, “BaseSystem.dmg” is the file that we need and it was hidden, so now you know that why we show the hidden files in above steps.

Open the Disk Utility again from “Applications” > “Utilities” > “Disk Utility” or by using Spotlight search.

Load the “BaseSystem.dmg” file into the Disk Utility, right-click on the file and choose “Open With” > “Disk Utility” option. After doing that open the Disk Utility and you will see the file “BaseSystem.dmg” is loaded in the Disk Utility on the left side.

Restore Disk Image

Now we are going to restore “BaseSystem.dmg” disk image on the USB drive.
Select your USB partition that we created in previous first steps, then click the Restore tab.
Under Restore tab there are two fields, Source and Destination.
Click and drag the “BaseSystem.dmg” to Source field and “osxyosemite” usb drive to Destination filed, see screenshot below to get more idea. When done hit the Restore button and you need to confirm “Are you sure you want to replace the content on USB drive with the content of disk image” so click the Erase button to confirm, after that you may need to enter the administrator password. Restoring disk image is time taking process so be patient.

Once the restoring disk image process is finished you will see a folder like this. Here, open the “System” > “Installation” folders and move the Packages file to trash.

Copy the “Packages” folder from the folder where the “BaseSystem.dmg” exist. and paste it into the Installation folder that you just opened in previous step.
