Catalan user interface for Microsoft 365 on macOS???

Hello,

Since I noticed that you are communicating in English, I will also use English to keep our conversation clear and fluent.

Based on the information you provided, I understand that you would like to use the Catalan language in Microsoft 365 for Mac. However, according to Microsoft, Office applications are only available in a limited number of supported display languages, and Catalan is currently not one of the supported Office display languages for Mac.

You can review the list of supported languages here: What languages is Office available in? | Microsoft Support

I understand how frustrating this can be, especially when you and other users would prefer to work in your native language. Please be assured that Microsoft continuously works to improve the user experience and expand language support based on customer demand and feedback.

To help improve the product, I strongly encourage you to submit your feedback directly through the Microsoft Feedback Portal. When creating the feedback, you can select any Office application, such as Word, Excel, PowerPoint, or Outlook. The Microsoft development teams actively review customer feedback, and many enhancements have been implemented based on community input. 

If you decide to submit feedback, please feel free to share the link with us. I would be more than happy to support it, and doing so may also help increase visibility so that other users experiencing the same situation can find and endorse it. The more engagement a request receives, the higher the likelihood that it will be carefully reviewed. 

Thank you again for clearly documenting your concerns. I sincerely hope this feedback will be reviewed and upgraded by Microsoft in the near future.
