Nein, es funktionieren sogar alle beworbenen Funktionen. Aber wie!
Um von Skype auf iTunes umzuschalten muss man unter dem Bluetooth Symbol in der Menüleiste von "Headset" auf "Kopfhörer" umschalten. Unpraktisch, aber gerade noch nachvollziehbar.
Damit die Programme Skype und iTunes das Umschalten mitbekommen muss man sie neu meist starten. Aber auch das klappt nicht immer. Die Töne kommen gar nicht, oder aber nur teilweise, z. B. nur Klingeltöne, aber keine Sprache. iTunes verstummt gerne nach einem Titelwechsel. Neu booten ist angesagt. Das Ganze wird gelegentlich garniert mit einem Farbrad über dem Bluetooth Symbol, mit dem Symbol "Bluetooth nicht verfügbar", oder einer leckeren Kernel Panic.
Windows 98 feeling!

Mit Bluetooth Handys hatte ich übrigens bisher keine Problem.
Wenn ich ein bißchen in der Konsole schmökere:

... lese ich da immer SIMBL, obwohl mein Ordner Library/Input Manager/Simbl leer ist.

Nachdem sich auch die Skype Gesprächspartner über Aussetzer beschwert haben, werde ich das Teil wohl zurückschicken müssen.
