ISSUE1 (Fixed in OSX 10.11) OSX Version: 10.9.3 and later including 10.10 Symptom: When a client device is not Bluetooth connected (i.e. the device icon is semi-transparent), the drag image doesn’t appear during dragging the device icon on Across Center. Cause: It comes from an OSX bug appearing on OSX 10.9.3 and later. The bug already had been reported to Apple and Apple had confirmed the bug. ISSUE2 OSX Version: 10.6 Symptom: It needs click-down for 1~2 seconds to start dragging a device icon and therefore dragging is not natural. Cause: The problem comes from OSX 10.6 itself. ISSUE3 OSX Version: 10.6 Symptom: The name of a client device cannot be changed. Cause: OSX 10.6 does not allow changing the name of a Bluetooth device and therefore you cannot change the name of a device even in the Bluetooth-pane of System Preferences.
