Buy the Crucial and save the money. I have never found any difference between name brand memory and Apple memory except the cost. This assumes your Crucial kit contains 1600 Mhz DDR3 SDRAM--if it does not find a kit that does. As far as warranty is concerned save the memory you remove and replace it if you need warranty work--I do that all the time to make sure I don't loose the memory I purchased.

One other possibility if needed--good luck.
