Language & Region preferences

Add and select the languages shown in OS X and in apps, and choose and customize the formats used to show dates, times, numbers, and currency.

To open this pane, choose Apple menu > System Preferences, then click Language & Region.

Preferred languages

The languages you want shown in OS X and in apps (for example, in menus and messages), and on websites (if available in a preferred language).

If OS X or an app supports the primary language, that language is used. If not, the other languages are used, in the order listed. You can drag languages in the list to reorder them.

If you add input sources, those languages are automatically added to the list.

Add and remove languages from the list.


The geographic region whose formats are used for dates, times, numbers, and currencies.
