I can't get handoff to work properly. I can make/receive calls/texts from my cMBP to my iPhone 5. However, I can't get Safari handoff to work on either. I don't see the icon on the dock of my cMBP or on my iPhone 5. Both are on the same Wi-Fi network, both have Bluetooth on (though the cMBP does not see the iPhone 5), both are using the same iCloud account, and both have Handoff enabled. Any thoughts?
