I have 3 Mac's. (Macbook, Macbook Pro and iMac) Do I need to download El Capitan 3 times?
II have downloaded El Capitan on 1 15" Macbook pro. Is the downloaded file somewhere that I can copy it to my other 2 Mac's in order to save downloading another 12 gig?
MacBook Pro (Retina, 13-inch, Early 2013), iOS 9.0.2
