Do you know the speed, timings and recommended DRAM voltage for the memory that is already in your mac? Need to know these values in order to recommend a compatible expansion kit.

I'm assuming you have free DIMM slots on the notebook's motherboard?

Either of those kits would work fine. If it were me I'd go with the least expensive of the two. Who needs "Apple/Mac" certified. Sounds like a marketing scheme to me
