So disappointed
I suspect Apple is using a new factory in China or has a new production line. Sometimes there are many bugs to work out in these things. I purchased a IMac in 2008 and loved it. In 2011, I wanted to upgrade, as I'm a photographer and my files are getting larger. First I bought the most expensive Mac Pro laptop they sold, $3200. When I received it, the screen just blitzed. They declared it "dead on arrival and took it back, no problem. Then I went to the Apple store and bought an IMac again, as I had good luck with the one bought previously. Sad to say, it was no faster then the one bought in 2008. So I took it back and upscaled to a Mac Pro and 30" Cinema screen. On the advise of the store employees, I didn't upgrade with Apple ram, but purchased 16 gigs on-line. The computer had Major problems. Spinning wheels, slow performance etc. But I let the return date pass, so was stuck with it. Took it in for a fast drop, they kept it 3 days and after getting no call, I went to the store. Said they couldn't replicate the problem, but no explanation of why 3 days and no call. Felt they were blowing me off by this time. Did a diagnostics text myself, holding the D button down and it came up with a error message about the ram. The on-line company sent me new ram and the machine worked fine. But when I did another diagnostics, it just got stuck at 1 hour and 40 minutes. Called Apple care. Major Mistake! Admittedly I was upset, but their technique of handling upset customers is the pass them to other people and make the experience "UNPLEASANT" Each person I talked to "3" said they would explain the situation with the next so I wouldn't have to start from ground zero again. Next person would start with, "Heard you have a spinning wheel or something to demonstrate I would have to start over again. Thanks Apple Care, just what I need when in this kind of nightmare. Last "senior tech" said to call back in a while, but gave wrong call back number, "THANKS". When I did reach his extension, he had gone home for the day. THANKS APPLE CARE ! No one ever explained why it was stuck, just said let it run longer. Last A. Care person I talked to, seemed to take delight in pushing a phone button repeatedly, so I took that loud beep in my ear every 20 seconds or so. So finally I let it run 11.5 hours, and still stayed stuck. I e-mailed Apple, saying I would take a hit of $600 or so, if they would just take it back, but no response.
Again, this seems so unlike Apple, so I suspect a new production line or factory being used. As for Apple Care? The people are either poorly trained or simply don't care to use even the most basic decency expected from a business.
All statements based on my experience.
