A 2010 15" Macbook Pro 6,2 with Intel & nVidia Chipset will only support 8GB (2x4gb) in OSX - you can run 16GB (2x 8gb) in Linux or Windows - but there does not seem to be a workaround for OSX yet. Even with 1x 8gb you will find the same artifacts, random restarts and kernel panics. Here's a popular thread on Apple forums: https://discussions.apple.com/thread/276... Its long - but basically, there are no confirmed cases of 16GB running on a 6,2 MBP 15" w/ both Intel and nVidia Graphics in OSX.
