Oh, Thanks @TParsons, I should mention that the issue is (and was) MacOS specific, at very first time.  
I am sorry.

Have you tried PsychoPy’s new Keyboard class?[https://www.psychopy.org/api/hardware/keyboard.html](https://www.psychopy.org/api/hardware/keyboard.html) It supersedes the event module and provides much better timing. I’m not sure if it will handle the actual returned characters any differently, but at least it is more likely that we can get changes made to the source code if required.

Pushing the A key results in a letter a unless the shift key is held down, when you get a A. If you push either ctrl or command then no letter is typed at all, and a quite different event occurs. PsychoPy, meanwhile, is operating at a very low level, being concerned with things like when a particular key is pushed, and also when it is released. We don’t wait for the …

Now the issue seems resolved, but unexpected crash after several random key inputs.  
(I tried to figure out the rule, but couldn’t find.)
