Lets not allow this go stale. What is blocking it? Can the CI be bumped to check how it fits with recent movement of Cog branch. @eliotmiranda, are you satisfied with Ronnie's commit 6e1da75? @fniephaus, unless its blocking, lets move any macOS version bump to a separate issue. @johnmci, are you available to review? otherwise please advise us not to wait.
