I have the system crashing problem with this MBP;
MacBook Pro (15-inch, Mid 2010)
Processor 2.66 GHz Intel Core i7
Graphics NVIDIA GeForce GT 330M 512 MB
OS X Yosemite 10.10.2 (14C1514)
The system has always seemed flakey, though I thought it was due to software compatibility issues. I never believed it was due to faulty hardware. Recently the wife started using FCPX for editing HD video, the MBP would crash on her every time she would perform basic rendering. I started digging into MBP crashing problems and came across many discussions about Apple selling faulty logic boards in their products. I made an appointment at the local Apple store, explained the challenge we were experiencing. After the tech ran some tests, this appeared on the screen of my MBP.
He then went into the back room to discuss the situation with a few of the other techs at the store. At that time he suggested I can either purchase a new system, pay $640 for a replacement logic board or contact Apple Support to see if they would offer another solution. Even though he is aware of this problem, he explained that not enough 2010 MBP systems experienced the logic board failure issue for Apple to acknowledge a problem exists. I also spoke with Alex Marr in Applecare support, he repeated the same canned statements as the in store techs.
From what all the Apple reps have told me is it comes down to numbers. More 2011 MBP owners raised the faulty logic board issue than 2010 MBP owners. Therefore 2010 MBP's are not recognized as having a factory defect. Another huge problem is that people have had their logic boards replaced and the same failure occurs again with the replacement logic board. I do not want to pay $$$ for a replacment which will not last a reasonable amount of time; Apple only honors their work and hardware for 90 days. Apple reps are instructing customers to purchase new hardware every three years. I've never purchased any product this expensive or that was considered 'high-end' with the expectation I will need to replace it after three years. This is immoral, dishonest and should be illegal, though unfortunately it is not.
