Apple accepts Macbook sparks is a fault!
This is significant.
Following from my earlier posts.
Apple replaced the first sparking Macbook. BeforeI took delivery I asked the Apple technician to check the replacement and it had the same problem.
Apple then 'shut me out' by trying to tell me it was normal, then telling me it was due to my third partY equipment - this despite their own technician's report that it was due to the computer itself and the fact that my equipment did not cause the problem on my son's identical Macbook.
I eventually took Apple Pty Ltd to the Victorian Civil and Administrative Tribunal (VCAT). (Australia). It took many months but eventually I got a phone call from Apple wanting to 'discuss' the problem - as they had just received the paperwork from VCAT telling them they were going to have to front up in court.
So guess what, they offered me my money back, but I wanted the extra costs as well, which I got. Apple did not want to appear in court for obvious reasons.
So the lesson is this.
THERE IS A REAL PROBLEM WITH MACBOOK USB SPARKS. THIS IS ACCEPTED BY APPLE, SO IF THEY TELL YOU THEY HAVEN'T HEARD OF IT BEFORE, DON'T BELIEVE THEM. REFER THEM TO THESE POSTS.
DON'T GIVE UP! APPLE WILL DO EVERYTHING THEY CAN TO AVOID ADMITTING THERE IS A PROBLEM, AND TO AVOID PAYING OUT FOR FAULTY PRODUCTS.
DON'T TRUST APPLE. THE TECHNICIANS SEEM HONEST, BUT THE 'CUSTOMER RELATIONS' PEOPLE ... WELL THE LESS SAID THE BETTER.
