I recently switched to zsh on my Terminal.app on my OS X machine successfully. The version number of zsh is 4.3.11.

FYI, zsh version 5.0.5 comes with Yosemite 10.10.2. – Fortyfive 27/4, 2015 at 23:10

Run upgrade_oh_my_zsh in the terminal – Sensorium 21/7, 2020 at 6:25

If you have Homebrew installed, you can do this.

# check the zsh info
brew info zsh

# install zsh
brew install --without-etcdir zsh

# add shell path
sudo vim /etc/shells

# add the following line into the very end of the file(/etc/shells)
/usr/local/bin/zsh

# change default shell
chsh -s /usr/local/bin/zsh

Until recently, I'd Homebrew but I choose to uninstall it on purpose since it was messing with gem installations and it was really frustrating to find a workaround. Thanks anyway. – Middlebrooks 15/7, 2013 at 12:55

@CanSürmeli Homebrew shouldn't mess with gem installations—I use both it and Rubygems all the time. Homebrew's very useful and it's worth fixing whatever problems you're having with it. That said, I don't know that I want to use it to replace Apple's zsh... – Embryotomy 3/12, 2013 at 16:0

The directions here aren't replacing Apple's old zsh, but showing you how to make the new version available. The old one will still be available to use if necessary. – Eastwards 1/2, 2014 at 16:54

Does anybody know what the --without-etcdir is for? – Copperhead 26/3, 2017 at 14:30

@MikeLi and @PhillipMöhler what is the purpose of skipping /etc/zshrc? It seems like a strange thing to skip to me. – Contributory 11/6, 2018 at 15:33

Be aware that you may need to install some softwares again (e.g. rbenv) after doing this. – Fribble 26/10, 2018 at 8:24

I'd also love to know why this brew install zsh should be done --without-etcdir – Lemaster 26/11, 2018 at 4:43

I'm guessing the --without-etcdir has something to do with manually installing this... (editing /etc/shells to add the path to the brew installed zsh) - anyway, this option is no longer available. – Lemaster 26/11, 2018 at 4:47

that option no longer seems to be necessary. My dotfiles repo's .zshrc file with zgen is working just fine following these commands. Although the option is no longer available, I think it's ok to attempt to use the option. It just ignores it. – Lemaster 26/11, 2018 at 4:54

The option is no longer ignored, but throw an error and halt installation. The CLI flag semantics appear to have been reversed. Now you have the option to --enable-etcdir See: github.com/Homebrew/homebrew-core/blob/master/Formula/… – Legendary 6/2, 2019 at 0:25

Did it exactly except I ran this instead: "brew install zsh" and nothing happens. "zsh --version" still gives 5.3 (default Mojave zsh version). Edit: nevermind a relaunch of the terminal window fixed it. If anyone wants to skip the trouble, just update to the latest Catalina, that comes with the latest 5.7.1 zsh. – Kicksorter 28/11, 2019 at 6:21

I needed to use brew reinstall zsh instead as my mac has a zsh installed by default. Then I used zsh in the /opt/homebrew/bin/zsh instead of /usr/local/bin/zsh. And that worked as expected. – Archiphoneme 10/8, 2021 at 8:3

If you're using oh-my-zsh

Type omz update in the terminal

Note: upgrade_oh_my_zsh is deprecated

While this is not the actual answer to the OP, this is the answer to the question I meant to be searching for. Solved my problem. – Alguire 5/4, 2018 at 17:7

upgrade_oh_my_zsh is deprecated, but it worked for me. and then I executed omz update which is the latest command to update. Hope this helps someone. – Chloric 15/11, 2021 at 6:40

If you have Homebrew installed, you can do this.
