Have folks had experience installing 16 GB RAM in their Macbook Pros? I have a 15 inch late 2011 model (Intel Core i7) and I want to upgrade the memory. Apple's website says the limit on the model is 8 GB, but I see on some forums people talking about a place (Other World Computing) that sells 16 GB of memory for those models. I assume Apple is right? I would like to have the maximum amount of memory so i can run Logic smoothly.
