How can I set my default shell on a Mac, e.g. to Fish? [closed]

I do not like to retype fish every time I start terminal. I want Fish on by default. How can I set the Fish shell as my default shell on a Mac?

1. sudo nano /etc/shells

2. add /usr/local/bin/fish to your list of shells

3. chsh -s /usr/local/bin/fish

From Terminal:

1. Add Fish to /etc/shells, which will require an administrative password:

   sudo echo /usr/local/bin/fish >> /etc/shells
   

2. Make Fish your default shell with chsh:

   chsh -s /usr/local/bin/fish
   

From System Preferences:

1. User and Groups → ctrl-click on Current User → Advanced Options...

2. Change Login shell to /usr/local/bin/fish

   

3. Press OK, log out and in again

You can use chsh to change a user's shell.

Run the following code, for instance, to change your shell to Zsh

chsh -s /bin/zsh

As described in the manpage, and by Lorin, if the shell is not known by the OS, you have to add it to its known list: /etc/shells.

These are applicable to macOS v10.12.5 (Sierra) (16F73) and probably some other recent and upcoming versions of macOS.

1. chsh is not enough to change the default shell. Make sure you press Command + , while your terminal is open and change the 'Shells open with' option to 'Default login shell.'

2. In case of Bash, make sure that you execute echo $BASH_VERSION to confirm you are running the intended version of Bash. bash --version does not give you correct information.
