    Does exactly what it says on the tin

    Posted by Simon Uden on 18th Feb 2024

    I was a bit sceptical of buying this 32GB RAM pack, as Apple had stated that the 2011 iMac maximum was 16GB, but I was persuaded by various articles that it was okay and, indeed, the product description said it was okay for the Mac, so I went ahead. Very pleased as they work perfectly and now my old iMac has more memory than any of my other computers, and it's so cheap too!
