  • When I took my Apple 27-inch iMac mid-2011 into my local Apple retail store recently the Genius who was helping me said that “theoretically the four slots in my iMac could support 32 Gb, even though the technical specs say 16 Gb”. I am not sure if this is because the 8Gb RAM modules are the same physical size as the 4 Gb RAM modules, or not. Because if my iMac was designed to only access 16 Gb of RAM, I am not certain if it can actually use the 32 Gb even if it is present. I could not get further clarification on this question, and am waiting to order memory until I do.

    Good question. Please post the answer if you find it out for certain.
