           I know you will be eager to try the newly released OS X Yosemite 10.10.  If you are already download the Yosemite installer app from the App Store, then proceed to the bootable usb creation steps, otherwise download yosemite installer first.

After downloading the app, you will need the following.

2. A Mac running machine.
3. The downloaded OS X Yosemite 10.10 .app file (saved in the folder "/Applications/")
