I migrated Mac’s default shell from bash to zsh, so here’s a memo of the steps. (Last updated: 2014/11/19)

I don’t use the zsh that comes installed by default, but instead install the latest version with homebrew.

Preparation

Set the path to use zsh installed with Homebrew.

$ export PATH=/usr/local/bin:$PATH

Install zsh with Homebrew

$ brew install zsh
$ brew install zsh-completions

$ zsh --version
zsh --version
zsh 5.0.5 (x86_64-apple-darwin14.0)

$ which zsh
/usr/local/bin/zsh

Change Login Shell to zsh

$ sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells"
$ chsh -s /usr/local/bin/zsh

Creating .zshrc

Create and edit the .zshrc file to customize settings.

I mostly rely on oh-my-zsh, so I’ll install and configure oh-my-zsh.

Apply .zshrc Settings

$ source ~/.zshrc

That’s all.
