Closing :observer.start() window on macOS doesn't kill the app

I‘ll go away once you close the iex session.

What if I’d like to reopen :observer? Do I need to kill entire iex session?

@hauleth

It is because of the architecture of macOS and the limitation that only root PID can create window

Do you mean this is the case with other mac apps as well?
