Thank you Paul. I didn’t really think it was me but since nobody else had reported it here I entertained the possibility.

Over time, Apple has made more and more use of autolayout inside of its own interface objects. I (and I’m sure many others) have learned through hard experience that doing almost anything that affects the autolayout system on any thread other than the main thread is a recipe for crashes or other forms of aberrant behavior. As new versions of core libraries make more use of autolayout code for previously existing object classes, it becomes necessary for users of those objects to ensure that their code also runs on the main thread. These messages are simply informing us that this isn’t happening (which at some time in the future might turn into a runtime error) and the stack trace can help to identify the relevant code. As a matter of course I now do all interface code inside a call to ccl::call-in-event-process.
