my black macbook i abou 2 weeks old, and it has started ,mooing. is there something wrong with it that could damage it or is it just a simple problem. should i call apple or not. it really doesn't bother me that much
Mooing is harmless, but can obviously become an annoyance. I would take it back, even if it doesn't bother you because someday you might get annoyed by it and then it will be too late to return it.
