The other thing about Apple's software is that it neither fails gracefully nor does it warn the user. They give an appearance of "everything is fine" even when it isn't. They'd rather have an app crash and throw you to the homescreen rather than give an "app not responding" warning.
I seem to get such messages on v11.x. I also have applications that occasionally spontaneously exit, which I assume means bad error handling in the app, along the lines of "…else (exit);".
