I have an iPhone and iPad running iOS 13 but my older Mac Mini (2010) and MacBook Air (2009) are no longer compatible with Apple Continuity or Handoff.
Everything worked fine in iOS 10 and Yosemite. At some point Apple ‘broke’ this feature for older Macs without low energy compliant Bluetooth compatibility. I’ve tried rolling everything back to before but it seems like Apple changed the ‘rules’ somehow and now this feature no longer works.
I’d like to just have the Macs broadcast or advertise or handshake (whatever the protocol requires) as if they are low energy devices. Neither Mac operates without being plugged in so I really don’t care about the energy consumption or any additional radiation since the Bluetooth is always on anyway.
