Solution 1Recommended

Exit Full-Screen Mode in Excel

Since this bug primarily triggers when Excel is running in full-screen mode, switching to a standard window is the quickest and most effective workaround.

Testing indicates that worksheet tabs located in the middle of the screen may fail to respond properly to right-clicks when the application is maximized to full-screen on a Mac. Adjusting the window size restores normal functionality.

1
Exit full-screen mode

Hover your mouse cursor at the very top of your screen to reveal the Mac menu bar and window controls. Click the green circle icon in the top-left corner of the Excel window to exit full-screen mode. Alternatively, press Control + Command + F on your keyboard.

2
Right-click the worksheet tab

Navigate to the bottom of your workbook and right-click the centered worksheet tab again. The standard Excel context menu should now appear instead of the Finder menu.

Exit Full-Screen Mode in Excel
Temporary Workaround: This immediately resolves the overlap issue. You can resize your window manually to fill most of the screen without officially entering full-screen mode.

Frequently Asked Questions

Why does Finder open when I right-click an Excel tab?

This is a known interface rendering bug in Microsoft Excel for Mac. It typically occurs when the application is running in full-screen mode, causing right-clicks on centered tabs to misregister and interact with the macOS desktop or Finder running in the background.

Does using multiple monitors cause this Mac Excel tab issue?

Multiple monitor setups can sometimes complicate how macOS renders full-screen applications. If you use dual monitors and experience this bug, try moving the Excel window to your primary display to see if the context menu works properly.

How do I report the right-click bug in Excel for Mac?

You can report the issue directly to Microsoft by opening Excel, clicking 'Help' in the top menu bar, and selecting 'Feedback'. Be sure to mention that the bug occurs when right-clicking tabs in full-screen mode.
