At runtime: 10.9.5, 10.10.5, and 10.11.6. >The macro above only says “do this if I link against an SDK prior to >10.11” – that doesn’t handle what happens at runtime when you are on >10.10 or below.

Yes, I'm aware of these differences. I'm also aware, as you surely are, that sometimes behaviour depends (only) on what SDK you link against. If you scrub to around 43:37 here: <https://developer.apple.com/videos/play/wwdc2016/203/> you'll see they specifically refer to "linked on 10.11". Besides, I both build and run on 10.11.6 and yet I see these message-to-zombie crashes after removing the setDelegate:nil code.
