Oh, there's an installer app? I remember there being one in my launch pad for Mavericks but I couldn't find the actual install disk I'll give it and try and see if I can find it this time!Of course, just copy the installer app to the other mac and install there.
Yep. The trick is to grab the installer before doing the actual installation.Ah, after I downloaded Yosemite from the Mac App Store I checked in my Applications and there was an installer there. I just threw a copy in my public folder and downloaded it to the other machines! Worked great.
