How can I get ^C to show up when I do Control-C on a Mac terminal?
I'm not entirely sure of this, but for a different reason I upgrade the Bash on my machine (brew install bash) and this behaviour started to show up. This post is what I followed to update Bash. It would be good practice not to overwrite your old Bash but instead just use the new one. Brew puts the new Bash at /local/usr/bin/bash anyway.
