Okay so first off I am on GM on my iPad Air and iPhone 5. I also have the newest dp on my macbook pro retina So handoff is working between every device to all devices. It works between iDevices, and stuff from my Mac will show up on my iDevices, however if I have an email open on my phone or iPad it doesn't show up in my dock on my macbook. Does anyone else having working 100% Basically long story short. Handoff is working 100% accept for switching from iDevice to Macbook. Anyone have any ideas.
