I have a program that invokes the say command line utility on my mac that stopped working after I upgraded to macOS Sierra.

When I try to run the /usr/bin/say command from the command line, it just hangs (requires a ctrl+c).

If I run as root, it works just fine. I can’t figure out what changed in Sierra that would cause this odd behavior.

It was a compatibility issue with tmux. Works as expected outside of tmux sessions.

Make sure the reattach-to-user-namespace program installed and add lines like the following to your ~/.tmux.conf, when you run "say" utility inside of a tmux session.

brew install reattach-to-user-namespace

# In .tmux.conf:
set-option -g default-command "reattach-to-user-namespace -l zsh"

# To kill your existing tmux server (and everything running “inside” it!):
tmux kill-server
