I have a mid 2012 retina macbookpro with the 500 GB apple SSD that is now out of space. I logged onto OWC to see about getting a 1 TB SSD and am disappointed to see that the highest capacity drive you can put in the mid 2012 macbookpro retina (remember these are not standard SSDs to save space in the retina model) is 480 GB. This smells like Apple's built-in obsolescence in overdrive. Upgrading storage midway through a computer's life has been an upgrade option for computers since, well, there were computers. I am annoyed that I can't extend the life of this 2 year old machine by putting a decent 2014 sized SSD in it. While this could be that OWC just has decided not to make a 1 TB option for the 2012 model, I suspect apple has done something to the 2012 to prevent a larger drive from working. Very disappointing.
