A Mac with at least Mac OS X 10.6.8 operating system.
How to proceed
- Go to AppStore and download Install OS X Mavericks.app
- Format the USB Flash Drive as "Mac OS Extended (journaled)" – The "Disk Utility" App can do the work.
- Open a Terminal Window
- Into the terminal window run the following command:
$ /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ Mavericks.app –nointeraction
Now you can use your USB Flash Drive to install Mavericks on other Mac's.
