Logic board replacement confirmation
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.
