I bought this laptop, it worked well for a year, then it suddenly did not turn on. I took it to mac store and they say it was the motherboard, so they ordered a new one and my extended warranty covered it. Once they returned it back to me, a week later the screen was not working. So I took it back, and it has been months and still they have not returned me my laptop even tho its still in warranty period. They say they can't find that screen and there is a shortage worldwide for that screen. What is the point of buying a $3,500 laptop if I can't even use it.So they finally sent me the piece and got it fixed and gave it back to me. After one day of use the screen won't turn on again, and I took it again today. Now they tell me its the mother board AGAIN! I still have the warranty so they will change it but it will take time to get the piece again! So in total the laptop has been more time in the repair apple shop than with me. This is really bad! I will never buy an apple product again. $3500 dollars down the drain.In the end they gave me a new laptop because they could not fix mine, so I will keep buying apple products. It took 5 months tho, if your job depends on the laptop then its hard. But overall satisfied. Thanks.
