Hi, I understand that users of mac OS 10 were notified that the Terminal default-shell had changed from Bash to zsh. I have not seen that message since. However, my current MacBookPro running OS26.6.2 has just popped up that old message:

The default interactive shell is now zsh.
To update your account to use zsh, please run chsh -s /bin/zsh.

After all this time, should I be suspicious?
