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: Last login: Tue Sep 15 17:42:23 on ttys000 The default interactive shell is now zsh. To update your account to use zsh, please run chsh -s /bin/zsh. For more details, please visit https://support.apple.com/kb/HT208050. MacBook-Pro:~ [My Name$] After all this time, should I be suspicious?
