Content
I cannot reproduce the problem on macOS 10.13.3 with python 3.6 (but haven't spent much time on this). The combination of GUI code with multiprocessing is a known source of problems on macOS, the system libraries are hostile to that. Changing the start method from "fork" to "spawn" or "forkserver" should help with this, using multiprocessing.set_start_method(). This should be changed before doing anything that might Apple system frameworks related to GUIs.
