I have handoff setup among my three Apple products: 1. 2012 Mac Mini server running Yosemite 10.10 2. IPad air running iOS 8.1 3. iPhone 6 Plus running iOS 8.1 Everything works great between my iPhone and iPad air. When I open a handoff app on one device the other immediately responds with the expected handoff icon in the lock and multitasking screens. Everything also works great from the iPad Air and iPhone 6 Plus to my Mac Mini. I see the handoff icon to the left of the dock. But nothing works when I start a handoff compatible app on the Mac Mini, none of my other devices recognize the handoff and the icon never appears on the lock or multitasking screens. I have wifi turned on for all 3 devices and connected to the same network. Bluetooth is also on for all 3 devices. I've checked the options in system preferences and settings on all 3 devices to allow handoff, yet still nothing. I've signed in and out of iCloud on the Mac Mini but it's made no difference. It's like my handoff works in only one direction with my Mac Mini and that's to the Mini but not from it. Any ideas? This is driving me crazy.
