My 2011 Macbook Pro died i7 Quad core/nvidia. It has 16gb and a 500gb SSD. Now I'm trying to optimize a replacement. I'd like to get at least a 2012 with 2x Thunderbolt ports. I want to be able to use my SSD drive and memory. Depending on the web site I visit it is really hard to tell if the 2012 will take my memory and SSD drive. I'm looking for a definitive yes/no. I know the 2013 Apple soldered in the memory and went with the newer "chip like" SSD. It isn't so clear in the 2012 model. At least I've found enough conflicted web sites it beings me here to ask. Some, of these web sites must me wrong, but without being able to look at one myself and take it apart I don't know which is correct.
