Hello Gwen,
Is there any news on this topic?
I am experiencing similiar issues with my mid 2012 macbook pro - MD104LL/A
On top of this issue, my MacBook Pro runs really hot. I created a clean user and it runs about 70°C to 80°C in idle – and I think both problems connect to each other.
So I couldn’t solve it right now, but might have identified the source of bad smell in my case.
I have to say, I already replaced the old thermal paste and my system is cleaned. Sadly this didn’t give the results I was expecting, as temperatures kept beeing hot.
But, I figured out the bad smell might come from the keyboard itself.
In the macbook the CPU and GPU heatpipes run under the bottom of the keyboard with little to no space left. So the bottom of the keypad plastic and electronics is getting really hot as well.
I didn’t take any pictures, but please check out this fine youtube video. There you can see clear marks left from the heatpipes to the black bottom plastic of the keypad. 2012 Macbook Pro 15" A1286 CPU Heat Sink Replacement
I think this is the source of bad smell.
Also in my system, the little silver-colored-patch in the bottom left corner below the logic board is peeling of.
My system has a really bad battery too. So I’m swapping the battery. Maybe it solves the temperature as well.
In the next step I will swap the heatpipes and swap the fans as well. Hopefully this will achieve full cooling again to the MacBook Pro.
I’ve fixed the smelling issue with my one. Rather than the plastic that is off-gassing it is the thermal pads below and on top of the memory slots.
They have gone bad and were pretty brittle I’ve removed them and that removed the bad smell as well.
