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:

  1. From the Apple menu, choose App Store. Note that the Mac App Store is discussed in more detail in Lesson 19, “Application Installation.”
  2. In the search field of the App Store window, enter Mavericks and press Return.
  3. Find OS X Mavericks in the search results, and click the “DOWNLOAD” button under its name.
  4. Click Continue in the confirmation dialog that appears, then wait as it downloads.
  5. When it finishes downloading, the installer application will open automatically.

  6. Quit both Install OS X Mavericks and the App Store.

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

  1. Open Terminal from the Utilities folder.
  2. 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.
  3. Control-click the Install OS X Mavericks application, and choose Show Package Contents from the shortcut menu that appears.
  4. Packages are discussed in Lesson 14, Reference section 14.2.

  5. Inside the installer package, open the Contents folder, and then open the Resources folder inside that.
  6. Drag the file named createinstallmedia from the Finder window into the Terminal window.
  7. This inserts the full path to createinstallmedia into Terminal.

  8. Switch back to Terminal, and press Return.
  9. This executes createinstallmedia as a command-line program. It prints a usage summary, explaining how to use the program.

  10. Begin another command by typing “sudo ” (note that there must be a space at the end), but do not press Return until step 13.
  11. Drag createinstallmedia from the Finder window into the Terminal window again.
  12. In Terminal, enter the text “--volume ” (note that there are two dashes at the beginning, and a space at the end).
  13. Drag the “Install Mavericks” (or whatever you named it) volume icon from the desktop to the Terminal window.
  14. In Terminal, enter the text “--applicationpath ” (again, there are two dashes at the beginning, and a space at the end).
  15. In the Finder, navigate back to the Applications folder, and drag the Install OS X Mavericks application to the Terminal window.
  16. At this point, the Terminal command should look something like this (although the lines may wrap at a different point):

  17. Switch to Terminal, and press Return.
  18. This operation requires admin access, so it prompts for your password.

  19. 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.
  20. 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.
  21. Wait as the Install disk is prepared. This may take several minutes.
  22. When the process is complete, it prints “Copy complete.”, followed by “Done.”

  23. Quit Terminal.

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.
