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.

Hide the system files again using this command
defaults write com.apple.finder AppleShowAllFiles NO
