I went in very optimistic feeling like I had found a great deal on this Macbook Air. I have owned many Apple refurbished products in the past and have always had had a great experience. I will mentioned, that all of those refurbished product where purchased on the Apple site and not Amazon. My previous Macbook Air is from 2010 and it was also refurbished at the time of purchase and it's still kicking to this day. I wanted to update my tools as I am an Interior Designer and am in constant in person meeting with clients. Today was such an embarrassing day thanks to my new Macbook Air. I received this computer a few days ago, I downloaded that latest IOS and synced it with my iCloud. I started to notice that every time the computer sat idle it would completely shut down and after booting up every app and document would be erased. This happened several times and after messing around with some settings it seemed to be ok. Well today it happen again during a client meeting and my computer shut down in the middle of a presentation and tried to reboot 7 times. Mind you, the computer was fully charged and operating very simple task, a PDF file.That is all to say that this will get returned ASAP. I thought I was getting a great deal on this computer but I guess I will have to keep purchasing from Apple directly.
