Hi How long will it take to exchange an iMac through Apple Support? I called Apple Support about my exchange to find out, but the representative on the phone told me that there was nothing that she could do and that I needed to wait for the Returns/Exchanges department to ship out the new iMac. I returned the iMac on Dec 7 and Apple confirmed the return on Dec 11 (during the morning hours). This was my second returned iMac. The reason for this return was that there was a dent/dimple about 2mm in diameter on the aluminum frame that borders the outside of the screen. I noticed it right after turning on the computer. The first iMac that I received had a faint vertical line down the center of the screen, underneath the glass. It was not visible while the computer was on, but very noticeable when light shined on the screen when the computer was off. A Mac genius at my local apple store confirmed the defect and pronounced in DOA and created a RMA # for me. All I needed to do was call Apple Support and report my RMA # so that they could signal FedEx to e-mail me the shipping label; once my return was confirmed by Apple they shipped the new iMac right away. I am assuming that the reason why it is taking longer for Apple to ship my second replacement is because they need to confirm my reported defect before shipping a new iMac…but, on average, how long will this take? I tried to schedule an appointment with a Mac genius to look at my second iMac (just like I did with my first) so as to speed up the exchange process, but when I tried to call my local Apple store, the person on the phone said that this was a “shipping related problem” and that I needed to contact Apple Support to deal with this problem. Thanks!
