I'm running Yosemite public beta on my Retina MacBook Pro and iOS 8 on my 5s and iPad Air yet none of the Handoff features seem to be working. The settings are turned on for each device yet they aren't reacting to each other at all. Edit: Handoff is not supported on the Yosemite public beta. Edit 2: That's weird. Handoff has JUST started working between all devices. Seemingly triggered by disconnecting from Wifi and connecting again on my MacBook Pro??
