Good news for those running the public bet, you can use one of the continuity features, AirDrop to send files between your iOS devices running iOS 7 and OSX 10.10 so there's no need for iOS 8.
It's working for me when sending from the iMac to the iPhone, but not the other way around. I had to turn on my iMac's wifi for it to work (I normally leave it off since I'm connected over ethernet).
