Have this memory, despite the limitation on the part of Apple bought to 8GB total memory, and am very happy with it! Works flawlessly and with Corsair has also simultaneously bought brand memory. Compared to my PC retailers of memory was just under 40% cheaper here. But I still allowed myself the Morning Express and could ruckzuck install the memory in my MacBook. Work is much smoother possible (Lightroom, Safari, Mail, VirtualBox simultaneously) and you can see the colorful "Wait ball" no longer so often ;-)
Thanks for the smooth handling and for the Top merchandise!
