I have a mid-2012 Macbook Pro 13"with the original 4gb of RAM. I ordered 16Gb of memory from Crucial and, after three attempts and three returns I tried OWC. Same story, multiple returns and attempts with no luck. During my attempts with OWC they had me do a number of key stroke combinations. One of them corrupted my OS and had to have Apple do a clean install which wiped out my applications. I restored files from my back up which I do every day. A tech from OWC said this is a known problem with some mid-2012 Macbooks but they don't have a solution yet.
I'm going to upgrade to 8Gb and hope that it works. At this point, even though I have no problem swapping out memory modules, I'm going to let the Geek squad do it, so if it doesn't work it's their problem. I can bring my own memory but they have them there. I'm just tired of returning and working with tech support multiple times.
Any thoughts or opinions would be welcome.

It would be great if updates can solve the problem.
