This is to confirm that a KINGSTON KTL-TP1066/4G x2 will work on a MacBook Pro (MacBookPro7,1) – mid 2010.
Although there is no sign on the internet that this will work on a Mac, I had to take the risk and test it myself (having to order one from US all the way to Qatar). It works like charm, and my Mac is super fast again running the latest version of OS X.
Here they upgrade a Ram for around 215$, I ordered the 8Gb sticks for 65$ only! You can also order other types of Rams online just make sure you have the same specifications as the one mentioned in your current installed Ram. Feel free to ask me about the model you have on the comment section.
Happy upgrading folks.
