It is patched on Sierra, this was part of the 2017-002[0] security update on the 6th of December.

That link shows Meltdown in reference only to High Sierra, not Sierra. What am I missing?

You're right, can't believe I missed that.

Edit: See the archive[0] apparently I'm not going mad and it used to say that the patch was applied to Sierra and El Capitan, but Apple has since changed that.

Thanks. I thought I was going nuts, too.
