Hi. My rMBP 15" from mid 2012 was acting up for a long time and one day I ran into an article mentioning an extended repair program.so I took it to the closest Apple Store in Newmarket Ontario. They kept it and next day they called me saying they saw some issues with the video card and we’re keeping it to run some extensive test. A few days later I got a call and was told they replaced the logic board at no cost to me. When I picked it up I asked exactly what parts were on the board that were replaced. He said all of them. Apparently with the retina model everything is fastened down permanently. So in effect I got a brand new computer as the battery and track pad were replaced last year. The bill for the board repair would have been over $650. I asked if I went into About this Mac for a system report if I could confirm the repair was carried out. Well to my surprise nothing in the system info report gave me a clue about any parts when they were made. Not a single date of manufacture was listed. So I figured that Google would know how I could confirm that I actually got a new Logic board in my Mac. Not a single link to any help I could use. So here I am asking if anyone here knows how to confirm that my new Logic board is just that a new board with all new parts attached, processor 2.3 I7, 16 G of memory, 650 gt invidia video card etc. I also have a second question regarding the identity of the audio DAC built into the 2012 15" rMBP. I have a Schiit headphone Amplifier and was wondering about the quality of the DAC in the MAC. again no information on the Mac and nothing on Google. Although I did find out that 2014 models and on have an excellent unit. Again if anyone knows anything that can help me it is very much appreciated. Thank you so much for your attention. L.a.

There’s a out-of-warranty replacement program running indeed. Your 15"/2012 qualifies if the VGA fails. Once they determine that, they order and install a new logic board. Not to my knowledge a top case and battery which have nothing to do with the VGA. On that board, RAM, CPU, VGA are soldered. They are replaced for sure alltogether. The SSD is not soldered and I’m not sure they replace it, but I do know they usually make you sign a waiver for the data and usually install a fresh OS to avoid any issues from damaged OS. My 15" retina is suffering intermittently from video issues. A local Apple Certified Service Center tested it and it failed to qualify. They gave it back as is. In the meantime, I brought them so far 6 laptops 2011/2012/15" for my clients, and 5 of them qualified and had the logic board replaced for free (actually for a handling charge, as is common here). So when the laptop qualifies they say yes, and when it fails they simply give it back as is. No need or urge for them to make up a story about replacing it and make you wait 1 week for it. On the other hand, and that’s not uncommon, you could have another issue with your laptop that they missed and did not solve, such as a display issue. Or you could have software issues. When they got it, and saw it qualifies for the program, mays be someone assumed that was it, replaced the board and missed the remaining issues. It’s like when one goes to the doctor for some ailment and doctor finds cancer, forgets about the remaning stuff or pushes them back until cancer issue can be addressed.

Try downloading and running Coconut Battery. It will tell you the manufacture dates of the machine and the battery, how many load cycles it has. http://www.coconut-flavour.com/coconutba…

This is too much paranoia. No they do not build features into their operating system for people who do not trust that they replaced the board for you, that is a waste of their time! Is there any reason to not believe them? If this is that much of a concern to you, buy conformal coating pen like this http://www.all-spec.com/products/cw3300g… and put it under the wifi card where they can’t see it. If the green glob is still there when you get it back they didn’t replace your board.
