Setting Locale in Mac

April 30, 2021

If you have faced issues in your Applications, especially, terminal based programs, with regards to invalid Locale setting, please read on to know how to fix it.


  1. First of all, check your current locale setting using the command: locale

  2. Then, check the locales available in your machine using the ‘all’ option: locale -a

  3. Choose an appropriate locale for you from the available list.

  4. The last step is to add the below two lines into your init scripts(.bash_profile, .bashrc, .zshrc e.t.c)

export LC_ALL=<your_preferred_locale>
export LANG=<your_preferred_locale>


The init script is usually located in your home directory.

For bash/sh shell, the init script is located at ~/.bash_profile or ~/.bashrc

For Zsh shell, it is located at ~/.zshrc

In my case, I mentioned en_US as my locale since that is one of the most supported locales.

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

PS: If you still face issues with any of the applications, try using one of the more generic locales like en_US. Your specific locale might not be compatible with all the applications.
