[Microsoft Office][MacOS] Ribbon Tabs UI Bugs

Hi @Gordon Fang

Thank you so much for contacting Microsoft Q&A Forum.

Based on your description, I understand that after the recent Office for Mac update to version 16.102.1, the Word toolbar now improperly cuts off or overlaps the Ribbon Tabs when you enter full-screen mode.  

I have tested this in my own environment and can confirm that I am seeing the same behavior. Here are a few workarounds you can try: 

Method 1: Roll Back to a Previous Version  

This method depends on how you installed Office. 

+If you installed Office from the Mac App Store: You cannot roll back to a previous version. Your only option is to uninstall the App Store version of Office, and then reinstall it by downloading Office from the Microsoft website (see link below): 

Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac  

+If you installed Office directly from the Microsoft Website (Retail/Web Download): 

You can roll back > Uninstall your current version of Office > Go to the "Update history for Office for Mac" page and download the installer package for a stable older version, such as 16.100 or 16.99. 

Method 2: Adjust macOS Dock Settings  

Some users have reported that changing the Dock's behavior can help. 

Go to System Settings on your Mac > Click on Desktop & Dock >Find the setting "Automatically hide and show the Dock" and turn on "Automatically hide and show the Dock" > This will hide the dock when you do not move the mouse near bottom of the screen > Then, in Word app, you move the mouse to full screen button until it shows many options for screen mode, and you choose the fill option (look image below): 

Method 3: Use Word on the Web  

As a temporary alternative to keep your work going, you can use the web version of Word by logging into office.com.

We apologize for this inconvenience and thank you for your patience.

Try using Focus View instead [Shift+Control+Command+F to toggle if on/off]

When in Focus View move the pointer to the very top to expose Ribbon & Menu Bar, to the very bottom to display Status Bar. You also can press Option to display only Ribbon & QAT.
