It is supported actually since MacOSX 11.0 (Big Sur)+. We should be more specific with the filter condition. Can you check on what pipelines did it fail originally? FYI our other DontFragment test only filters out iOS+tvOS+Catalyst, but not sure if it's correct:

That is weird since those machines are running on 12.7.4. Regardless, I think this PR changes things for the better so I think we can merge this and open a tracking issue for the MacOS problem.

macOS did not support DF for long time at all. It does not surprise me that it does not work on dual mode socket. FreeBSD (and others) may be on the same boat e.g. it may be better to make this to running only on platfoprms where we know it works instead of excluding macOS

I think it OK. small suggestion for the test. |
