We experienced problems recently with RViz on OSX which hopefully should be resolved with this PR.
Could you try compiling RViz from source?

Also, I am closing this issue as because this ROS2 repo might not be the best place for it. For specific issues regarding RViz, I recommend opening tickets directly at the RViz2 repo.
