Is the official Apple Discussion forum of any use? From what I have seen - and I dont want to generalise - it seems you are often encouraged to be all nice and sweet. And the answers are stingy. The advice is fine when it has to do with end-user questions and which can often be found in the MacBook guide. But the advice seems absent if it is about potential faults with the Mac or other, more specialised questions. In fact, the advice seems as tepid as the geniuses on Apple stores. At least that is my experience.
