I want to upgrade all my home computers (4 macbooks running 10.8) to the new Mavericks OS.

I have a download cap, so i dont want to download it 4 times. How can i download it once and install it on all computers?

To quote Bryan Luby from "Re-use Mavericks install file"

Download the update from the App Store. Once the file has finished downloading, check your Applications folder for the "Install OS X Mavericks" icon. Copy this installer to your other computers before going through the install process. The installer will delete itself after the install is finished.

I recommend distributing the file between computers via AirDrop (if all your computers support it) or via File Sharing (from the Sharing pane of System Preferences).

Note: Running the update from /Applications/Install OS X Mavericks.app will DELETE the installer upon completion! Be sure to distribute the file to all your machines before installing it.

As an alternative to copying and running the installer from within Mac OS X, you can also create a bootable USB flash drive to install Mavericks on a Mac without any prep.
