Furthermore, how do I know which shell My Mac is running?
To do that, go to System Preferences | Users & Groups then right click your name and choose advanced options. There you should see a dropdown menu listing the available shells from /etc/shells. Pick the one you want. To find out what shell it's using, just launch Terminal and look in the title bar.
Additionally, how do you switch shells? To change your shell with chsh:
- cat /etc/shells. At the shell prompt, list the available shells on your system with cat /etc/shells.
- chsh. Enter chsh (for "change shell").
- /bin/zsh. Type in the path and name of your new shell.
- su - yourid. Type in su - and your userid to relog in to verify that everything works correctly.

Why did Apple switch to zsh?
The reason Apple has not switched to these newer versions is that they are licensed with GPL v3. bash v3 is still GPL v2. zsh , on the other hand, has an 'MIT-like' license, which makes it much more palatable for Apple to include in the system by default. zsh has been available as on macOS for a long time.
How do I change my default shell?
