[Solved] Handoff help needed after swap to BCM94352Z on MSI Z97I Gaming ACK

Hi,

So I have finally swapped my Killer Wireless N1525 to BCM94352Z (Dell DW1560 to be exact).
So far working:
+ WLAN 2,4 GHz
+ WLAN 5 GHz
+ AirDrop
+ Personal Hotspot (Internet working from my iPhone 6+ via Bluetooth)
+ Localization (Find My ...)

Not working:
- Hand-off

Hand-off do work with my Macbook Pro and iPhone 6+, but I do not get this to work at my custom iMac...
