How to set my default shell on Mac?

Question

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

Answer 1

This work for me on fresh install of mac osx (sierra):

1. Define current user as owner of shells

sudo chown $(whoami) /etc/shells

2. Add Fish to /etc/shells

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

3. Make Fish your default shell with chsh

chsh -s /usr/local/bin/fish

4. Redefine root as owner of shells

sudo chown root /etc/shells
