How to Change your Chrome Default Language

Open up a Terminal window. (If you have never seen Terminal before, go to Spotlight Search and type "Terminal.")

In the Terminal box, try this:

defaults read com.google.Chrome AppleLanguages

If you see this:

The domain/default pair of (com.google.Chrome, AppleLanguages) does not exist

... don't panic. It just means that nobody else has used this method before. To change your language, do this:

defaults write com.google.Chrome AppleLanguages '(pt-BR)'

Capitalization of the language code you enter is unimportant; your system will normalize it to lower-lower-UPPER-UPPER.

Here I've chosen Portuguese as it is spoken in Brazil. Feel free to enter the IETF language code of your choice; some of my personal favorites are en-UK, fr-CA, and es-MX. For a complete list, see the Wikipedia entry.

Restart Chrome.

If Chrome knows the language you entered, the top menu will immediately switch; mine says Arquivo, Editar, and Visualizar when I switch to pt-BR.

To switch back, run the same Terminal command with your preferred language. And if you're ever confused about what language has been selected, do this:

defaults read com.google.Chrome AppleLanguages

... or use a Web inspector to enter console mode on any page and type this:

window.navigator.language

Doesn't seem to work for chrome 89. Crashes on open.

It's working for me right now on Chrome 90.0.4430.85, no crash. Sorry about that!

To remove the setting, execute:

defaults delete com.google.Chrome AppleLanguages

God bless you man!

This also works for edge by using com.microsoft.edgemac or com.microsoft.edgemac.Beta instead of com.google.Chrome

thanks,

Thanks, it works.

For the Chrome for Testing app, use com.google.chrome.for.testing.

And if you are running Selenium Python:

            if sys.platform == 'darwin':
                # run a command to set the language to English
                subprocess.run(["defaults", "write", "com.google.chrome.for.testing", "AppleLanguages", "-array", "en"])

God bless you :D

And for Chromium use org.chromium.Chromium
