Bought this ram to upgrade a 2011 Mac Book Pro. It works well, and have seen a definite improvement using both FCPX and Motion5 , and some general speed increases.
With Motion 5 , the number of layers you can work with improves a lot, but playback, still relies on the graphics card, so is not greatly improved.
FCPX, was working on something with a lot of keyframing, and the increased ram, means that it is now usable, and not 'paging - out' after about 20 mins use.
so far so good...
