What is Bluetooth Handoff?
Bluetooth Handoff is a feature of OS X Yosemite 10.10 that allows you to pick up what you were doing on your iOS devices device with your mac. It works for Mail, Safari, iWork, Calendar, and Contacts. Sadly it does not work by default on Hackintoshes.
You must have iCloud working on your Hackintosh to enable handoff. For more information see Fixing iCloud and iMessage.
For Handoff to work at all, you first need Bluetooth working on your Hackintosh. Moreover, only certain Bluetooth chips appear to be working with the handoff. Here is a list of Working Adapters
The Azurewave AW-CE123H works best with this patch. If you are buying a Bluetooth adapter to use with the handoff, get one of these. It will fit PCI-e slots on desktops and laptops.
