    Worked like a charm

    By CuriousMarc

    from CA

    Verified Reviewer

    As usual, the Crucial selector found the exact right memory for my aging 2011 iMac with only 4G stock. Plug in an extra 4G, and voila, works like new again on El Capitan.

    Works just as I expected. My OS Sierra upgrade slowed the 2011 iMac down, and the extra RAM from Crucial brought the speed back to what I'm used to.
