Looks like the correct type. Crucial have an application that can scan your system, give that a go to be sure.Thanks.. I don't understand is this 1600mhz ?
You might also check Amazon. I know they have lower prices in the US on Crucial and other brands. I bought 8 gb for my MBP from a discount computer store for $59.99 USD from $79.99 normally. If you have one of those you might do some comparison shopping.Yes sorry my bad it's not the rMBP as I wanted to be able to upgrade parts i.e RAM - all order today
