Bevor ich ein Apple Fans bin,habe ich 4 Notebooks von Sony Vaio,nie solche Problems passiert.Und jetzt soll ich mal denken,für mein Macbook,Imac,Iphone,Ipod produkte,vielleicht brennt es,oder auch nicht.

Gruesse,

Ja, das stimmt.
Oursde is asking about a magsafe connector with a short circuit. "Had nobody seen it, might it have burned the whole room?"
The MacBook power supply does carry a CE mark and an Underwriters' Labs mark. Both certifications suggest the device has had to endure rigorous testing for safety. We hope the power supply has a safety fuse and self-extinguishing plastics that would fail to a safe mode before a fire.
Apple did publish a technical note about the magsafe connector:

What happens is the pins can get dirty and not make firm contact with the socket on the computer. The weak contact force creates a higher electrical resistance. The power supply compensates, keeping the current it feeds at a constant value. The current passing through the high resistance causes heat and melting of the connector.
What I can not answer with certainty is: does the over-heating always self regulate before a serious condition results. As far as I know, there has never been any report of fire even though the magsafe connector has been in use for several years.
