FULLY change Mac's default language (ex: recovery mode)
Hi,
I bought a used MacBook Pro 13" (early 2015). It is a french MacBook, meaning it has a French keyboard. However, I fully formatted it through a USB key with El Capitan pre-loaded, and chose English as my language throughout the setup. However, for some reason, some elements remain in French. For example, recovery mode is still in French by default. Also, oddly enough, the names of the tags in Finder are also in French, even though the whole computer and keyboard are set up in English.
Anyway to FULLY change the default language of my MacBook to English? I tried the sudo languagesetup command but that didn't fix it. I'm running 10.11.4.
Thank you!
MacBook Pro with Retina display, OS X El Capitan (10.11.4), 13-inch, Early 2015
