Yes, once we have a replacement (10.14 or ideally 10.15) in the CI. Unless you’re suggesting we drop macOS as a platform entirely?

We don’t have it in the CI due to problems virtualizing it, so it’s tested manually though developers working on that platform, and though user feedback.

As Oliver says, we should get 10.14 in ASAP, by possibly blacklisting failing test. This is something I’m looking at.
