Who knows pursued at Apple prices, the memory expansions are disproportionately expensive. Memory expansion to 16GB would cost 300. But the Kingston memory fits easily and with just under 75 and a working time of less than 2 minutes, it is a very worthwhile alternative to having ordered memory. I had ordered 2 single bolt, because the sets currently could not be ordered by Prime. In retrospect, I noticed that the 2 were together cheaper than a set of the same memory. Likewise, problems in a MacBook Pro 13 "(Mid 2012)
