Set the Language
You can set which language the Parallels Desktop interface uses by doing the following:
- Quit Parallels Desktop.
- Choose Apple menu > System Preferences > Language & Region.
- Drag the language you want to the top of the list. If you don't see the language you want to use in the list, click the Add button .
- Open Parallels Desktop.
If the primary language you chose is supported by Parallels Desktop, the menus and interface text appear in that language. If the primary language you selected isn't supported, menus appear in the first language listed that Parallels Desktop supports.
