    As far as I know, \a uses a hardware speaker that PCs use to beep during start up, etc. Maybe Macs don’t have this?

    From http://en.wikipedia.org/wiki/Bell_character:

    Modern terminal emulators often integrate the warnings to the desktop environment (e.g., the Mac OS X Terminal will play the system warning sound) and also often offer a silent visual bell feature that flashes the terminal window briefly.

    Can you try running the exe from terminal and seeing if anything happens?
