Exercise 4.3: Create an OS X Install Disk
Prerequisites
- You need an erasable external disk with a capacity of at least 8 GB.
- You must have created the Local Admin account (Exercise 3.1 or 3.2).
In this exercise, you will create an OS X Install disk, which not only includes the OS X Recovery environment and tools, but also a full set of installation assets. With a disk created by this method, you can reinstall OS X Mavericks without needing to redownload the installer application from the Internet.
Acquire a Copy of the Install OS X Mavericks Application
If you upgraded to OS X Mavericks following the instructions in Exercise 2.2 and saved a copy of the installer application, you may use it and skip this section. If you are performing these exercises as part of a class, the instructor may have provided a copy in the StudentMaterials folder. Otherwise, you can redownload the installer with the following procedure:
- From the Apple menu, choose App Store. Note that the Mac App Store is discussed in more detail in Lesson 19, “Application Installation.”
- In the search field of the App Store window, enter Mavericks and press Return.
- Find OS X Mavericks in the search results, and click the “DOWNLOAD” button under its name.
- Click Continue in the confirmation dialog that appears, then wait as it downloads.
- Quit both Install OS X Mavericks and the App Store.

)
When it finishes downloading, the installer application will open automatically.
Reformat the External Disk
Follow the instructions in the “Reformat the External Disk” section of Exercise 4.2, giving the disk a descriptive name (such as “Install Mavericks v10.9.0”) between steps 7 and 8.
Create an OS X Install Disk
- Open Terminal from the Utilities folder.
- Switch to the Finder, and open the Applications folder. You can do this by choosing Go > Applications, or with the keyboard shortcut Command-Shift-A.
- Control-click the Install OS X Mavericks application, and choose Show Package Contents from the shortcut menu that appears.
- Inside the installer package, open the Contents folder, and then open the Resources folder inside that.
- Drag the file named createinstallmedia from the Finder window into the Terminal window.
- Switch back to Terminal, and press Return.
- Begin another command by typing “sudo ” (note that there must be a space at the end), but do not press Return until step 13.
- Drag createinstallmedia from the Finder window into the Terminal window again.
- In Terminal, enter the text “--volume ” (note that there are two dashes at the beginning, and a space at the end).
- Drag the “Install Mavericks” (or whatever you named it) volume icon from the desktop to the Terminal window.
- In Terminal, enter the text “--applicationpath ” (again, there are two dashes at the beginning, and a space at the end).
- In the Finder, navigate back to the Applications folder, and drag the Install OS X Mavericks application to the Terminal window.
- Switch to Terminal, and press Return.
- Enter the Local Administrator account’s password (ladminpw, or whatever you chose when you created the account), and then press Return. Note that nothing displays as you type.
- Since this operation will erase the disk, you are prompted to confirm the operation. Verify that the volume name (listed after “/Volumes/”) is the one you intend to use, and then enter “Y,” and press Return.
- Wait as the Install disk is prepared. This may take several minutes.
- Quit Terminal.
Packages are discussed in Lesson 14, Reference section 14.2.
This inserts the full path to createinstallmedia into Terminal.
This executes createinstallmedia as a command-line program. It prints a usage summary, explaining how to use the program.
At this point, the Terminal command should look something like this (although the lines may wrap at a different point):
)
This operation requires admin access, so it prompts for your password.
When the process is complete, it prints “Copy complete.”, followed by “Done.”
Test the OS X Install Disk
Follow the instructions in the “Test the OS X Recovery Disk” section of Exercise 4.2, but note that the disk will have the name you gave it in the previous section.
