My reply to "helpme05" was intended to suggest to him that there may BE such a product from OWC in the future, because iFixIt's teardown of the newest MacBook Pros shows that the SSD still plugs into a (mecahnically and logically different from that on the 2012 and early 2013 machines) motherboard socket. Of course, that's not relevant for the OP, who has a late 2013 MacBook Pro and wants a bigger SSD. I may not have been clear enough in my post OWCs SSDs will NOT work in the late 2013 MacBook Pros (they've clarified their website product description to make that abundantly clear) the newest MacBook Pros use PCIe controllers, both for the SSD interface and for the SDXC slot the 2012 and early 2013 MacBook Pros use SATA the two are NOT interchangeable, and OWC doesn't make ANY SSD cards that will work in the newest MacBook Pros (yet).
