Hi, From what I know, the late 2011 models should be able to take 2x 8gb RAM. So I just got mine from Crucial today & put it in. Now the system (10.7) tells me I've got one bank of 8gb. And the other slot appears to be empty. Is this normal? I mean - is it just that the SYstem Profiler displays the wrong numbers, but I can actually use 16gb?
