I have my Mac OS X Yosemite system configured in spanish, but I have an app with a horrible spanish translation, and I would like to run it (and just this app) in english. How could I do that?

  • On what device? And maybe in settings there is an option to set another language... – k1r8r0wn Dec 19 '14 at 9:34
  • Oh, sorry, I forgot to tell. It's a Mac OS X Yosemite system. I edited the question. And no, the app itself has no option to set the language. – César García Tapia Dec 19 '14 at 9:38
  • See the answer below – k1r8r0wn Dec 19 '14 at 9:44
  • Yes, it is a duplicate, I'm sorry. – César García Tapia Dec 19 '14 at 10:23

So... there is two ways: change the main system language for some time or use this freeware, Language Switcher, which helps to launch single applications with a different language. Also you can try this variant - App Language Chooser.


You may try to move translation files out of application bundle. First make a copy of Your app (just in case). Then go to the Resources folder inside this app-copy (right click -> show package content -> enter Content -> enter Resources). Here You'll probably find directory called like: es_ES.lproj/es_lproj/es_MX.lproj (or similar) - delete this dir. Launch this app-copy and check the language.

This is a bit overkill since You can use -AppleLanguages switch. Good answers in: Is it possible to launch a program in a specific language?
