Upgrade of mid-2012 MBP to 16GB RAM actually work?

[Drew1]

Hi guys
I too bought the 16gb memery from crucial whicb worked fine while I had yosemite/Mavrick... the minutd I upgraded to El Capitan... the **bleep** broke loose! Even Apple at first could not find thd reason and blamed the motherboard and changed it for nearly £500.. it still did NOT work...
In the end Apple realised that the issue was with the combination of new operating system and old MacBook pro (2012 15 inch) which according to them is made to have max 8gb Ram!! So they refunded me for the motherboard and put. back 8 gb ram... now everything is working fine!!
Hope this helps... though I dont know whether the 16 gb ram would work with Sierra now... I am too scared to take that chance!!

Hi,

I have a MacBook Pro 13 inch (Mid 2012), Processor 2.5Ghz i5, and just upgraded from 4Gb memory (2Gb per slot) to 16Gb (8Gb per slot).

Running macOS Sierra prior to the upgrade and now - so far no problems to report at all.

All I can say is positive: Mac running like it should, no daisy wheel, no delay, no hiccups -just quick and smooth, the way it used to be.

3 days running and no issues. Keep your fingers crossed for me and my Mac

I am having an issue with my mid 2012 13" 2.9Ghz where the "bottom" sodimm slot is causing instability when it is full - started 2 weeks ago with the stock 2x4GB chips and i tried to upgrade to 2x8GB but the instability was still there. I read on another thread that removing the bottom chip (the one closer to the keyboard) could prevent the system crashes, and it seems to be working... Is it possible to get this mac to recognize a single chip of 16gb such as: http://www.crucial.com/ProductDisplay?urlRequestType=Base&catalogId=10151&categoryId=&productId=5745...
