Oh i am not so happy, i got the new iMac and guess what. After 2 days it started making this interesting noise also.
I work in complete silent most of the time so i can hear it, no concert here.
I have still not sent back the "old" iMac, but i think i figured out how to fix that one at least. I changed the power cable to a old black one i had at home.
I feel like more people then me should have this problem if it is so common, what do you guys think?
(Both imacs have similar serial numbers.)
Thank you
