Follow @statropy Getting started with zsh I just recently made the switch from bash to zsh. I started trying zsh after updating my mac to Catalina and getting this message: 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. I had pretty much only used bash to that point. I started slowly with zsh, not changing the default right away as I wasn’t quite ready to give up on bash just yet.
