How to Switch the Default Shell to Bash on macOS

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.

bonben@Killer ~ % chsh -s /bin/bash
Changing shell for bonben.
Password for bonben: 
bonben@Killer ~ % 

Killer:~ bonben$ bash
bash-3.2$ bash --version
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin21)

bash-3.2$ 

Change the default shell back to Zsh by running this command the reopen the Terminal window.

chsh -s /bin/zsh

You can see a list of included shells you can select by running the following command:

cat /etc/shells

bash-3.2$ cat /etc/shells 
# List of acceptable shells for chpass(1).
# Ftpd will not allow users to connect who are not using
# one of these shells.
/bin/bash
/bin/csh
/bin/dash
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh

3. Right-click your user account’s name in the left pane and select Advanced Options.
