The OS X Mavericks released last month October 22, in Apple Special Event October 2013.
Now OS X is releasing in App Store only. So you can’t get install media such as DVD, USB Stick.
But I want install DVD.
Why?
・DVD is cheaper than USB Stick.
・Probably I think that I lose a USB stick. Because it is too small!

This is how to make Mavericks’s install DVD. If you want too, try it.

1. Make the install DVD
1. Download Install OS X Mavericks.app in Mac App Store.
2. Type bellow command in Terminal.app to show the hidden files (This process is performed for the work of the back).
$ defaults write com.apple.finder AppleShowAllFiles TRUE
$ killall Finder
3. Right click on Install OS X Mavericks.app and choose “Show Package Contents”
4. Double-click and mount the Contents > SharedSupport > InstallESD.dmg.
5. Then you may sea the BaseSystem.dmg. Right click on BaseSystem.dmg and choose “Open DiskUtility” (BaseSystem.dmg is hidden file).
6. Burn the DVD select with BaseSystem.dmg
7. Complete burn-in the disk, “OS X BaseSystem” will mount on your Desktop.

2. Install OS X Mavericks
8. Reboot by System Preferences > Startup Disk and choose “OS X Base System OS X 10.9″.
Rather minute later the install dialog will launch.
9. If your home network use static IP address, follow No.9 steps. If you use DHCP address then step No.10.
9-1. Run the Utility > Terminal, and type 9-2, 9-3.
