I'm having trouble with the latest edition Matchbook Pro which I've had for around 4 months, The left fan is constantly making a grinding noise every time I turn it on and it won't stop. This is my first Mac and the noise is so unbearable that I can't use it. Anyone have any ideas because I use the Mac all the time, Thanks
