Problem of handoff between iMac 2013 and iPhone 6 Plus
I have three devices: iMac 2013, Macbook Air 2012, iPhone 6 Plus.
All the Mac has been upgraded to Mac OS X Yosemite from AppStore.
And iPhone 6 Plus is on iOS 8.1 beta 2.
Now I have a problem, I can use handoff feature from MacBook Air <-> iMac, or MacBook Air <-> iPhone 6 Plus.
However I can't handoff between iPhone 6 Plus and iMac.
Did someone has the problem?
iMac (21.5-inch, Late 2013), OS X Yosemite (10.10)
