One of the coolest software features Apple unveiled on stage during WWDC 2014 may not be available to all iOS and Mac users, German publication Apfeleimer speculates. “Continuity” / “Handoff” or the ability of iOS 8 and Yosemite users to pick up actions started on one platform and continue them on the other – including calling and full SMS support for Macs running Yosemite – may only be available to iOS and OS X devices that have Bluetooth 4.0 LE support, which is apparently needed to establish a connection between devices. Apple has not explicitly detailed how the feature works when it comes to the actual connection between devices, saying during the presentation that iOS and OS X devices need to be close for continuity features.
