Thanks @agueroveraalvaro
Your command worked for me and the /etc/shells file shows the new entry for /usr/local/bin/zsh
Also i executed chsh -s /usr/local/bin/zsh command
But echo $SHELL still shows me /bin/zsh instead of /usr/local/bin/zsh
Can you please help?

I had the same issue on Mojave 10.14.5, this was resolved for me by using the answer provided by @XerxesNoble above:
chsh -s /bin/zsh
thanks for this awesome docs
// register our zsh to the shells, idk why "sudo -s" is showing not below error on my mojave:
/bin/bash: echo /usr/local/bin/zsh >> /etc/shells: No such file or directory
// instead do register below to also avoid: "chsh: /usr/bin/zsh: non-standard shell"
sudo sh -c "echo $(which zsh) >> /etc/shells" && chsh -s $(which zsh)
Also, don't forget to re-open your terminal and re-setup all "recommended" zsh option.
Or if you want to re-configure/forgot to configure it, you run this command below:
The function will not be run in future, but you can run
it yourself as follows:
autoload -Uz zsh-newuser-install
zsh-newuser-install -f
Tried the OSX install script and got an error:
ruby -e "$(curl -fsSL https://raw.zshhubusercontent.com/Homebrew/install/master/install)"curl: (6) Could not resolve host: raw.zshhubusercontent.com
replace
zshhubusercontentwithgithubusercontent
I got this error when i try to install zsh, i dont know what I should do.
@DanielMarinBeltran your system seems quite mess up.
brew executable is not in your $PATH. I can see that you tried to add it, but it seems like something didn't work. Also, whenever you adapt .zshrc, you need to evaluate it again using source ~/.zshrc or (better) start a new shell/terminal. Did you even have zsh installed at that point? Because you try to install it below.brew couldn't download ncurses (which I think is required for zsh) because the SSL/TLS versions seem to mismatch. Make sure you have an up-to-date computer.
could someone help me please?
I downloaded home-brew and I keep trying to download ZSH but it keeps showing me this message
/Users/vanessarowe/.zshrc:source:75: no such file or directory: /Users/vanessarowe/.oh-my-zsh/oh-my-zsh.sh
vanessarowe@Vanessas-MacBook-Air ~ %
what do I do?
@vanessarowe Hm, it seems your system is a bit broken as well. The error message is not related to ZSH itself but to Oh my ZSH which is a plugin system for ZSH.
Because it complains about .oh-my-zsh missing in your home directory, I assume that you don't have Oh my ZSH installed but a reference to it in the ZSH config file .zshrc.
You could remove the Oh my ZSH reference from line 75 of .zshrc in your home directory and try again.
Thanks @XerxesNoble yours work for me
