How to change the Chrome default language on OSX

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 AppleLanguages

If you see this:

The domain/default pair of (, 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 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 AppleLanguages

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