First, a bit of old news. Apple (AAPL -0.57%) apologized to Chinese consumers last week for failing to live up to expectations for warranty and repair service. CEO Tim Cook promised to do better in a letter reminiscent of an earlier mea culpa over Apple Maps.

Why bring this up now? Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova also insists that Cook's apology -- his second -- reflects a broader trend at Apple, and one that should have investors concerned.

In the following interview with The Motley Fool's Erin Miller, Tim says that Apple may be losing the swagger that was so visible during Steve Jobs' tenure as CEO, replaced by Cook's easy, mollifying demeanor. Thus far, investors haven't seen any benefits from the shift.
