Right now I am about to throw my Macbook out the window. It has had the high pitch buzzing sounds since new. When I take it in to the Apple service centre they can not here it. Both my mum and dad can here it so it is not me. CHEEKY BUGGERS. What I was just thinking is would it be a good idea in your mind if I update this other wise perfect computer to a newer model. Or another idea I had was buy a monitor and use it with the lid closed. Has this work for anyone else. CONFUSED. Or am I over reacting.
