    Hi there,

    I'm looking at upgrading my iMac's RAM (27 inch, Late 2012, 8GB). I just checked on Crucial and it is saying I can upgrade it to 16GB, but my iMac has four slots, so why is 32GB not being offered as an option?

    Any advice, as always, greatly appreciated.

    Thanks

    I don't know for sure obviously but I've heard that you can upgrade beyond that limit. I'm going to be doing it with my iMac 21 inch late 2011 model. Once I do I'll confirm on here.

    32 GB is the maximum supported. Actually, the Crucial site shows a 16 GB Kit (8GB x 2) .

    I've the same as Proteus Zero, with a 3 TB Fusion drive (replaced with the Seagate Apple recall).

    I ordered two 16 GB kits the moment I finished placing the order for this late 2012 unit. They got installed before it ever saw the power cord when it was new.
