Controlling Windows Input Language In macOS
While you're working with Windows or any Windows applications, Parallels Desktop shows the input language set in Windows in the macOS menu bar. While working with Windows in Coherence, you may find it useful when the guest OS desktop is hidden.
As soon as you switch to Mac, the input language in the macOS menu bar changes back to the language that was set before you started working with Windows.
Change Windows Input Language from macOS Menu Bar
To change the Windows input language from the macOS menu bar:
Click Windows or your Windows application to make it active.
Choose the language you need from the Input menu available in the macOS menu bar.
Note: The language you're selecting from the Input menu must also be available in Windows. To learn how to add a language to the list of input sources in Windows, please refer to the Windows help resources.
If the Input menu isn't available in the macOS menu bar, you can set it to show by doing the following:
In macOS, choose Apple menu > System Settings and click Language & Text.
Click Input Sources.
Select the language or languages you want to use from the sidebar.
Select Show input menu in menu bar.
