    Update Sierra on iMac 27" Late 2013 to which MacOS?

    Hi all, I'm thinking of upgrading my MacOS Sierra on my Late 2013 27" iMac to a more recent OS. The main question I have is which version of Mac OS should I upgrade to that will maintain both functionality and speed. I have already upgraded the RAM to 20Gb. Thanks Simon. :)
