I have a kit of 2x4GB Corsair Vengeance DDR3-1600 SODIMM laptop memory (CMSX8GX3M2A1600C9), will work with any laptop that can support atleast 8GB, including Macbook (2011 and up)
This is the exact same kit:
NCIX - Buy Computers, Computer Parts, Laptops, World's Leading Discount Computer Store
Reason for selling is this was a replacement from Corsair, but by the time I got the kit back I had already purchased another kit for my Macbook Pro.
Asking $50.
