Apple is now using Zsh as the default shell on macOS. But the trusty old Bash shell is still included with macOS, and you can quickly switch back to Bash if you prefer. Zsh became the default in macOS Catalina and higher version of macOS.
Change to Bash Shell from the Terminal
To change a user account’s default shell on macOS, simply run the chsh -s (change shell) command in a Terminal window.
Change the default shell to Bash by running the following command:
chsh -s /bin/bash
You’ll have to enter your user account’s password. Finally, close the Terminal window and reopen it. You’ll be using Bash instead of Zsh.
